Prototyping Advantages and the process of Rapid Prototyping

Prototyping

Invention Prototype is a process of software development wherein physical objects are automatically constructed by means of SFF or solid freeform fabrication. In the process of rapid prototyping, a prototype or working model can be constructed quickly, and tested for its functionality, performance and output. The new features or ideas can be illustrated well in the prototype and early user feedback can be gathered with regards to the product. There are numerous advantages of rapid prototyping.

Benefits of Prototyping : Significant advantages of rapid prototyping include reduction of project cost and risk. Generally, one or more prototypes are developed in the process of software development in a series of incremental and iterative steps. Every prototype that is manufactured is based on the previous designs’ performance and it is a corrective process through which the past design defects or problems are corrected. The product is readied for production when the prototype is refined as per requirements and meets all the design goals like manufacturability, robustness and functionality.

Another great advantage of rapid prototyping is that it finds use and application in almost all the industries. The other advantages of rapid prototyping include the following.

Visualization capabilities are enhanced in the early designing phase with use of Invention Prototype . The user gets a fair idea of how the final product will look by observing the working model in early design stage.
The design flaws can be detected before manufacture process is initiated. 
Whats nice about rapid prototyping is that you can have active participation in the development from all parties involved. Communication with the end users of the product and the manufacturer is very important.
The user is able to get a higher output.
The development costs are reduced considerably, hence rapid prototyping proves to be quite cost effective.
Rapid prototyping increases the speed of system development.
With rapid prototyping, it is possible to detect deficiencies in the earlier prototype, coding activities and requirement analysis.
Rapid prototyping assists in refining the potential risks that are involved in the delivery
The different aspects of the prototype can be tried and tested and immediate feedback is possible form user.
Better communication is enabled between the users and designer as there is clear expression of requirements and expectations in the start itself.
Rapid prototyping enables easy delivery of high quality product.

Time and Cost Benefits: With Rapid Prototyping you really save a lot of time and development costs. Time can be saved by reducing the amount of time required to produce the prototype parts and tooling. Production costs are lowered as the mistakes regarding tooling are identified in the early stages and hence, the modification costs can be cut down in the actual production.

Advantage of Innovation: Rapid prototyping can be used in many innovative ways. Sometimes you can find firms that do even more innovative things with rapid prototyping so the possibilities are endless. The advantages of rapid prototyping in innovative applications are advancement of new testing procedures and analysis, production tooling manufacture, improved communications across production departments and support of customized manufacturing. The new technologies can be used in a cost effective and successful manner with innovative applications of rapid prototyping.

Prototyping vs Rapid Prototyping

Prototypes

Prototyping can be defined as the process of constructing physical objects automatically by making use of ‘solid freeform fabrication’. The initial techniques regarding Prototyping came into being in late 1980s. They were then used for producing prototype parts and models. In today’s world, they are being used for much wider applications. For instance- manufacture of quality parts. This technology is used by certain sculptors for producing complex shapes in order to display them in ‘fine arts exhibitions’.

Origin: Prototyping has taken virtual designs through ‘animation modeling software’ or ‘computer aided design (CAD)’. Thereafter, transformation into virtual, thin, horizontal cross-sections takes place. Each cross-section then gets created in the physical space. This process goes on till the model gets completed. It is better known as WYSIWYG process. Let's understand this process in detail.

WYSIWYG: WYSIWYG as the abbreviation for ‘What You See Is What You Get’. It is used in ‘computing’ for describing a system wherein content looks similar to final product at the time of editing. It is generally used in word processors. However, this use is in the form of HTML (Web) authoring. The popularization of this phrase was carried out by the comedian ‘Flip Wilson’. His character ‘Geraldine’ used to say this very often to give an excuse against her idiosyncratic behavior.

This expression came to be applied later to computer-based applications as practicality in technology arrived. At times, it is phonetically spelt as ‘Wizzywig’ or ‘Wizywig’. It has also been used as a brand name for a ‘lighting design tool’ utilized in theatre industry to pre-visualize the shows and 3D CAD.

The process further : The additional fabrication causes the machine to read data from CAD drawing. What you will find next, is that you will have layers of powder, sheet material or even liquid that are laid down. Likewise, a model gets built-up from a chain of cross-sections. Such layers, corresponding to CAD model’s virtual cross section, are then fused automatically or joined together for creating the ultimate shape. Real simply, the biggest advantage for additive fabrication is that you can really creating any shape or object by using this funtion.

The CAD software and machines are interfaced by the ‘standard data interface’ in the ‘STL file format’. The function of STL file is approximating the shape of an assembly or a part by making use of triangular facets. Surfaces of higher quality are produced by smaller facets.

The word ‘rapid’ can be used relatively. The construction of models using present-day methods could take time ranging from a few hours to a few days. This depends on the technique used, along with the complexity and size of the model. What is nice if you are pressed for time, the additive systems will take less time. They can produce models within some hours. Some techniques such as ‘solid freedom fabrication’ make use of two materials for construction of parts. Your first material will be called part material and the next material is known as support material. The removal of support material takes place by heat. It might also be dissolved with water or any other solvent. Plastic products that are going to be produced in large quantities you will find that injection molding is a cheaper alternative.

Spyware Removal Tools What To Look For

Computers which crash on a frequent basis can be very frustrating when we have taken measures to prevent them from crashing. Certainly, all the information technology that is at our disposal is used, but this doesn't necessarily help us. Staring a system off clean and requiring password access is usually the first step.

Then the programs that are needed for the business and the owner are uploaded, and these files are double checked to make sure they did not include any nasty secondary programs. An additional precaution is that any availability to the internet should be severely limited, as to prevent the downloading of harmful programs or connections that will bring additional problems.

While company email and networks are open to most workers, programs like internet messengers or online shared programs are not, which goes a long way in ensuring the productivity of the workforce. Truthfully, it is impossible to prevent employees from using office computers to chat or download files not related to office duties. Cyber industry's major pain is actually spyware and or adware, something that can cause major problems for your business.

Once the internet and computer industries began booming, spyware was not far behind them, the negative ramifications predictably following the positive ones. Sometimes negative actions become so popular that a large swell of people will choose to take part in these negative actions.

Though the person behind spyware may be a genius, they are also a traitor to all the victims, many of whom are unaware of its existence until it messes up their system. Spyware gathers information about a user without them knowing or consenting, and there is certainly nothing right with these actions. The tools used to accomplish this privacy invasion are, unfortunately, completely proliferating.

This software works by sending advertisements to pop up on your system, and material will be downloaded on the system whenever you try to close the ad or type anything in the box. This is a difficultly reality to get out of, and the best you can hope for is that the people responsible can be tracked down and made to stop their nefarious actions. Illicit programs and malware can come bundled with the legal programs and services of an entirely different company.

Though there are many adware spyware removal programs, their efficiency in removing adware or spyware is flimsy at best. You may find an adware spyware removal program that works, but you have a much greater chance of finding one of the dozens of con spyware removal programs that function instead as additional spyware waiting to be downloaded onto your system. Any adware spyware removal program that you have your sights are should be thoroughly researched, and once a keeper is found, that adware spyware removal program should be held on to with dear life, for they are rare specimens indeed.

CNC General Overview

CNC

You will find in different magazines that people rate a CNC Router as one of the best tools to have in your shop. This is a versatile tool that can make things a lot easier for the person using it.

CNC actually stands for computer numerical control and it is a machine that works through the use of a computer that reads a particular code called a G-Code to make certain parts. This computer does the work by cutting away materials that the code tells it to cut. The machine has certain parameters that it works within and these are determined by a software program.

Before CNC machines, there were NC machines which stands for numerically controlled and the problem with these were that you could not change their parameters that they worked within. As the popularity of these machines grew the DIY CNC came into being but used the old NC styled hardware. Eventually the programs became more sophisticated and used floppy disks instead of punched tape to transfer the codes to the machine until it eventually evolved to what is in place today.

CNC machines were responsible for changing the manufacturing industry. These machines could produce curves, straight lines or complex structures in 3-D without much human interaction. In fact, the machining steps that were required for a human to do were reduced to just a few steps.

As these machines continued to improve and automation began to be instituted in the processes for manufacturing, the CNC machine again improved and decreased the error frequency while improving quality. This automation helped the operator's production overall. With the CNC automation it brought more flexibility to the way parts were held in the process of manufacturing and it reduced the time it took to change the machine in order to produce different types of components.

Today, there are a variety of uses for the CNC Information machines and they are controlled through computer files that were created through CAM software packages. This enabled any part of the assembly process to go from design to manufacturing without a drafting plan created on paper.

CNC Machines also are something like a robot system because they can be programmed to do any kind of machine operation that has been programmed into them. They can also run 24 hours a day. If you are worried about a problem with the computer program there are systems out there now that will place a call when there's an issue.

Through the use of the software programming the CNC Information machine can cut curves, drill holes, tap, repeat the processes in a series --as an example a series of holes spaced so many spaces apart and it can support logical commands.
There are many different types of CNC machines including routers, wood routers, lathe machines, mill machines, plasma cutters and more. You have several options if you want one from buying one new to making one yourself; there are many plans on the Internet to show you how to build your own.

Basic Casting Information and Metal Casting

Casting Information

Home Metal Casting is an ancient technique that has a variety of applications and purposes. Civilizations from the dawn of time to present day have used metal working as a way of creating artistic, religious, and practical items. The process of metal casting involves melting metals at high temperatures and using molds to then shape the metal into new items. The furnaces used in metal casting helped pave the way for the Industrial Revolution, without which the course of history would be dramatically different. Metal casting is just one form of metal working that has seen a recent surge in popularity as resources are becoming more affordable and communities are springing up to share information, ideas, and projects.

Metal casting requires specialized equipment, knowledge, and some creativity. While metal casting is used on an Industrial level as the process cuts cost and proves to be highly efficient, many individuals participate in metal casting as a hobby and in artistic endeavors. Many people are drawn to metal casting for one reason or another, although there seems to be two main motivations that stand out. The first motivation that brings hobbyists to practice metal casting is need; people may need to create items or parts for other ventures. Metal casting is a great way to build hard to find pieces for models, restoration projects, and even just small replacement parts needed for common household items. Another reason for using metal casting is so you can create some very creative designs.

Whatever the reason, small scale Metal Casting is attractive because that it can be done right at home, either in the backyard or workshop. Individuals working in metal casting are able to create home made tools and equipment like furnaces and molds. Metal casting is only limited by the individual’s desire, so for those with the time and the need, virtually anything is possible.

The actual casting process in Home Metal Casting has several forms, the most popular being sand casting. Sand Casting uses a mold that you create and then pour metal into so you can make a certain shape. Next, the metal needs to cool for some time at room temperature and then the mold be removed. This type of casting proves to be the most economical, but other types of casting can provide fuller detail and higher quality results.

As you can imagine, you have to melt metal in order to do metal casting so it can be very dangerous if you aren't careful. The melting points of several metals are well above 1,000 degrees Fahrenheit, or 530 degrees Celsius. It is vital that anyone wanting to work with metal casting take all the proper precautions. Safety advice can range from simple  common sense such as "never look directly into a high powered flame" to more specific warnings such as "when molten metal contacts a nonporous surface with water it is liable to explode, splashing hot metal everywhere." The use of appropriate safety gear such as gloves and goggles is necessary as well.

With time, dedication, and some know how, anyone can practice the craft of metal casting. Metal Casting is a very enjoyable and rewarding craft but it does require a certain amount of education to get started.

The Basics of Casting Resin

Casting Resin

DIY Metal Casting is known and loved for the high temperatures, glowing molten metal, and the possibility to make nearly anything. Metal and their alloys are not the only things that can be used in casting. Casting in plastic, most notably resin casting, is becoming popular with artists and jewelers looking for something odd and unique.

Resin casting does not involve the use of furnaces, crucibles, or casting sand. In fact all one really needs for resin casting is a mold, some resin (of course), and time.

There are actually two forms of resin casting. The first kind is the one that more closely resembles metal casting, uses a mold and even gates and runners if it's complex enough. The second type of DIY Metal Casting is simply incasing an object in the resin. An example of this is using an ice cube tray and placing an object like a small pendant in one of the tray's cavities and then filling it with the resin solution. After the resin dries you can pop it out of the tray. The pendant is now encased in hard plastic. People of different ages and different experiences usually use this form because its really fun and easy. At the very least it's a great way to get rid of some of the clutter around your house and disguise it as art. You can cast leaves, coins, and other objects in the resin to make anything from charms to magnets.

Resin casting using mold is generally used by those who work with models and miniatures. Resin casting is a great way to make several pieces at once so you can avoid shelling out money you may not have and waiting several weeks for delivery of your items. Who has that kind of time anymore?

Like DIY Metal Casting , resin casting will require you to build a mold. If you are fortunate enough then you can easily find pre-made molds, especially if you are working with miniatures. If you don't feel like buying these pre-made molds or just like doing things the hard way, then you will have to make the mold yourself. Don't worry, it's still fun.

You will need to find a molding box this will hold the rubber that will be used to make the actual mold until it dries. Many who work with smaller objects find that working with toy building blocks to create this molding block work extremely well and will provide added convenience. A wooden box will work as well, of course. The box, or flask, will not have a top or bottom, just the four walls. Place molding clay at the bottom of the flask and insert your original. Make sure to add a way for the resin plastic to enter the mold. The funnel or cup as some casters call it should be put at the very top of the mold. You are going to prepare the silicone rubber and catalyst which will be used to create the mold. Follow the instructions on the labels since each type will vary. A process called degassing can be used which will remove all the air bubbles from the rubber. This is a fun process involving a vacuum pump.

Slowly pour the rubber into the flask, covering the original. This can take up to a day to dry, so be patient. Remove the molding clay and repeat the process using the bottom part of the flask, or drag. Of your two parts that you now have, its the original that is in the middle. When dry, remove the mold from the box and very carefully split the mold to remove the original.

Place the mold back together and prepare the resin solution, follow the instructions to the letter. The resin should be poured into the top of the mold where you put the cup. The set time for the resin should be stated on the bottle, but for most it will take up to 30 minutes. In order to remove the cast you need to crack the mold open when you are ready to see your cast.

Resin casting can be a great family craft project but just make sure to follow all of the safety guidelines. This type of casting can still be dangerous even though you are not dealing with molten metals. Often times, the solutions and chemicals used in resin casting are poisonous if consumed. Not to mention that resin casting can be a bit smelly so working outside or in a well ventilated room is advisable.

CNC Lathe Overview

CNC

A CNC lathe is a machine that can spins material to do a variety of operations like sanding, drilling, cutting or sanding. Usually a lathe is used for more intricate cuts and
Today, they replace the older multispindle lathes because they are easier to set up and operate.

A CNC Turning will use carbide tooling and is designed using a CAM process which creates a file that can be uploaded to the machine at a later time. The reason these are so popular is because you can set the machine once to do several pieces and it will continue to do them until you have programmed it to stop.

Each CNC lathe has a computer control that allows the machine to be controlled electronically, and this program can be modified to do a variety of things. When an operator runs a CNC Lathe they have to have a lot of skill to understand the programs and how the programs to do the work.

 You can work with wood when you use a CNC wood lathe or various metals depending on the project you are doing. The wood lathe can be used for wood but also for brass and
Aluminum. There are also metalworking CNC lathes or milling machines that cut metal. You can do tapered work with these, drill holes, and create screw threads and more with these lathes.

Some CNC lathes are portable and others are stationary. In many shops for people who do woodwork for a hobby you would find a lathe because it is capable of making a lot of different designs and intricate cuts for things like stair railings, trellis' or table legs.

The point of using a CNC lathe is to make a piece of material that is symmetrical and beautiful. This is done by placing the material in a machine and allowing that piece to be spun until it reaches the specification that was programmed into the computer. The cutting tools then move around it on the Z and X axis to cut away the material that isn't needed to make the piece.

The process that the CNC Turning does is called turning and it can do a variety of shapes when it goes through the full process. Many machines are used to create a plain surface to make contour shapes, to taper the ends of some pieces and it makes threaded surfaces. Sometimes people really want to make some creative metal shaps and you can do this and turn as much metal as you would like. In some industries they use a CNC lathe to fabricate parts that may have a cross section that is to move in a circular motion.

Any material can be used as long as it will hold up during the turning process while the software program is continuing its revolutions.

If you are looking for a machine that can turn a few peices in a rown that are the same size and shape, then you are good with a CNC Lathe. They do have their limitations but for the most part you can create nice pieces with this type of machine.

Learn about Lost Wax Casting, Casting Wax and the Basics of Lost Wax Casting

Casting Wax

Metal Casting is an ancient technique that has been used to create very complicated metal castings and involved pieces that would other wise be impossible either because of economic reasons or manufacturing reasons. Everyone from small jewelers to large industrial foundries can use Lost Wax Casting. This process is also called Investment Casting when it is used in commercial industries. There are a lot of people who use lost wax casting for their casting needs but usually its the jewelry makers who you see using lost wax casting.

DIY Metal Casting is the ideal and preferred method for artists who are interested in making items like sculptures or rings from a variety of alloys like bronze, steel, or copper. This process is quite involved but not all that complex as long as you have some kind of metal casting know-how. For anyone wanting to experiment with different casting methods Lost Wax Casting is a great option because it involves a few materials and methods that are not normally found in other methods like Sand Casting.

The most noticeable difference of Lost Wax Casting from other castings is exactly what's in the name; the wax. To use Lost Wax Casting you do not necessarily have to be an artists but some skill in sculpting might be nice. You are going to start off by creating a sculpture from wax that will be the original.

You will then create a mold of the original. The mold is usually created from plaster with latex lining to help preserve the details of the original. If this is your first attempt at Lost Wax Casting you may want to make an original without a lot of detail just to get the feel for the entire process and so you do not become discouraged if something does not work out. Remember metal casting is a skill that must be learned by research, trial, and error. Chances are that you will not be completely successful, the first time around. The original piece is usually lost after the construction of the mold. This is normal and if you do want to prevent this from happening you can create the original from material other then wax like a metal alloy.

When the mold is ready you are then going to pour molten wax, you're not ready for metal just yet, into the mold. The amount of wax that you need depends on the thickness that you need for your design. Once the copy is ready, you are going to remove it very carefully from the mold. You will remove any of the impurities from the copy. This is called chasing.

You will then sprue the copy. Spruing is the act of carefully placing paths that will let the molten metal in and air out. Afterwards, a ceramic shell is created around the copy. The shell isn't really ceramic but a combination of liquid silica and sand. Traditionally, and in some areas still, animal dung and dirt is used to create the shell. The choice of which shell material you want to use is up to you. The shell is hardened in the kiln and the wax melts out. If you want to reuse the wax then collect it during this step. Wax can be reused a number of times and if you are on a budget or are just trying out different designs and methods, collecting the wax is encouraged. Once the wax is gone and all that remains is the hollow shell you will want to run water through it to make sure there are no leaks. If there are then you will need to patch them before pouring the molten metal.

You are going to want to reheat the shell before pouring the metal to avoid shattering the shell. The shell is still on the sprue tree so pouring the metal is an easy process. When the metal has hardened, then break the shell carefully and remove the cast. Afterwards, it is up to you to finish the piece to your liking and preference.

Lost Wax Casting process is an enjoyable experience but it does use a few tools that you might need to purchase before hand, like the wax and spruing tree. At the very least, you might want to try Lost Wax Casting once or twice to get a feel for it. This way you have another casting process at your disposal.

Basic CNC Lath Parts Information

CNC

There are many components of a CNC lathe machine and they are important to the function of the process. As you could imagine everyone's CNC Lathe works differently because of the differences in what each person does.

All CNC lathe machines have at least a headstock, carriage, bed and tailstock. Many have stable bearing surfaces that are broad and they work with excellent precision. When the machine is stable it can manufacture parts that meet the requirements for both repeatability and tolerance.

Here are the major parts of the CNC Lathe and the function of each:

Headstock: There are many parts to the headstock and this is where many of the functional pieces of the machine reside. In this area you will find a few things, such as the spindle, the gears, and the speed change control. Within the headstock you will have a strong design because it has to cut with a variety of force. If it were light it would create problems with vibration that would distort the finished piece and destroy its quality.

Bed -- the bed is actually the base of the headstock and it allows connects to it. The bed helps set the carriage and the tailstock in perfect parallel alignment to the spindle axis. A part called a way holds the carriage and the tailstock onto the track. What is used in this situation is a rack and pinion system that travels along a carriage. It also includes a leadscrew that keeps it on am accurate pitch or it has a feedscrew.

Feed or Leadscrew -- both of these helps with the gears of the CNC lathe machine. The feedscrew is the drive shaft for the machine and works with the gears to drive the mechanism of the carriage. The feedscrew is also driven by either the quick change gearbox or the change gears. There are other gears that allow for the correct ratio so that the parts that are made are accurate.  The feedscrew and leadscrew work together with the spindle to make the correct amount of screw threads on the work that you are doing.
Carriage -- within the carriage is the tool bit that turns either in a perpendicular or longitudinal direction depending on how the operator controls it. The operator will set this on a CNC Lathe where it would use a handwheel on the older machines. The handwheels are there and can be used to manually move the carriage or to automate it. Also, the handwheels have calibrations on them for ease of use.
Cross slide -- this is a small part that sits on top of the carriage. It has both a main spindle axis and a leadscrew. The leadscsrew actually moves along the main spindle axis in a perpendicular fashion so that it can perform facing operations; only one direction can be done at a time.
Depending on the CNC Lathe you have, there will also be a computer component where you can program either the CAD or CAM program to do exactly what you want it to do. Although these machines seem complicated, they are not as difficult once you start to use it.

Simply Upgrades For A Faster Computer Or Laptop - How To Upgrade Your Memory

Technology never seems to stop racing ahead and before one product has even gone to market quite often it has been superseded by a newer faster model.

Technology geeks (I can say that because I am one myself) go out and buy the latest gadgets at the highest prices because they all have some new fangled function or a re sporting the latest colors or designs when they haven’t really used all the functionality of the one they already own.

When it comes to the family Pc however I think the technology giants like Intel, Amd, Hp and Dell for example are all missing the point when it comes to your average consumer.

A majority of computer users do not play games on their computers (they probably have a play station or a Wii), nor do they use massively processor hungry applications like computer aided design packages or finite element (fea) calculation packages.

Computer vendors would have us believe that we all need multi processor cores so we can multi task and have a finite number of applications running it the same time when in all fairness most users will never have more than three or four applications open at any on time.

One fact that is undeniable though is that when you go and buy your next Pc with all its raw computing power you will probably still need to by something extra to make it work efficiently within a short space of time.

A well rounded and efficient computer or laptop isn’t just about the processor speed, granted that does help but only up to a point, but your system does need to be in balance and, a majority are not.

What we are talking about here is the amount of memory in your Pc, or should I say the lack of it.

As Pc power increases programs get more complex, and as they get more complex they use more computer memory.

The more programs you install even if only working in the background i.e. virus software, music editing programs and other favorite utilities the greater the system memory will be used and so it goes on.

Simply put the more memory the programs have to access, the faster and more efficiently the Pc will work.

This is all well and good but the problem occurs when your computer runs out of memory and has to start using the hard drive as extended memory instead.

This is magnitudes slower performance wise than the system memory and will not stop your Pc from working but will certainly slow it down, sometimes to the point of almost stopping.

Computer memory upgrades are easily obtainable fortunately and something which you can do yourself. You can do an online computer memory scan to ensure and guarantee that the memory is indeed correct for your system and fit it yourself when it arrives a few days later if ordered on line.

To see how easy it is to install extra memory in your computer or laptop, simply visit the computer support and repair and watch the video.

Or you can contact you local computer repair professional who can also perform this inexpensive task if you have already purchased a new Pc or if your existing system is running slowly.

Learn About Iron Melting and Iron Furnaces

Iron Casting

Many believe that DIY Metal Casting is just simply out of reach for small furnaces but this is not the case. While alloys like aluminum are more prevalent in home foundries. Artists and hobbyists have also used brass, bronze, and even iron to fulfill their casting needs.

Industrial foundries commonly use iron for a variety of items like cookware, like cast iron pans, and even bridges. Casting iron provides an easy and effective method of making such large structural pieces and even smaller pieces for around the home.

The most common furnace type used by home foundries is the cupola furnace. The cupola is a basic furnace type that does not need a crucible as it allows the caster to pour the molten metal directly from the furnace into a ladle which is then poured into the mold. Cupola furnaces resemble smoke stacks and can be home made for those with enough confidence and some mechanical know-how to attempt it. The various fuels that are needed to heat the particular types of metal really depend on the casters preferences. Many will use propane and some will use coal. There are a select few that will use waste material such as old scraps of metal and the powder at the bottom of bags of barbecue coal to fuel the cupola. For iron many would recommend the use of propane, but there have been some casters that have succeeded with waste material. Its good to experiement with different fuel types so you can find the one that is right for you.

Finding a source of iron can be difficult and a trip to the scrap yard might be in order. This is just one of the exciting ventures that DIY Metal Casting can provide you. After you locate your iron you will need to prepare your mold. This is assuming you have a pattern in mind that you want to cast. If not, then go ahead and figure something out even if it’s a small piece in order to test your iron casting ability. Since sand casting is the most popular casting method you might want to use it for the iron casting especially if you are familiar with the method and not with iron. 

After making the sand mold and placing the runner for the molten iron you will melt the metal. The melting point of iron is 2,800 degrees Fahrenheit or about 1538 degree Celsius. Since all metals melt at different temperatures don't be impatient if iron takes longer to melt and don't be surprised if it’s quicker.

When the molten iron is ready you are going to pour some into a ladle and the pour that into the sand mold. What is holding the sand mold together is the top and bottom of the mold which is called the cope and drag. The runners are in place in the mold to allow the molten iron a place to enter. When the iron is cool, remove the cast from the sand carefully and there you have a cast of iron.

Always take time to follow the right safety tips so you can be as safe as possible and avoid accidents. Accidents with molten metal will always be very painful so make sure you wear gloves, jeans, boots, and a long sleeve shirt. You may also want a heavy duty leather apron and a pair of goggles.

Iron Casting is a great way to create restoration items or pieces for around the home and even for artistic purposes.

Gravity Casting is more than just an excuse to play with molten metal it is actually a great way to create art and complicated pieces of machinery or other items that would otherwise be nearly impossible to make. Metal Casting is really a great way to save money...while playing with molten metal.

The reason that DIY Metal Casting has survived the test of time is a matter or efficiency. Some of the earliest casting examples have been found in China dating back thousands and thousands of years. In fact every major civilization from the Egyptians to the Romans practiced metal casting. This skill came back into vogue during the Renaissance and has continued to advance and evolve from there. While Sand Casting is the most popular casting process there are many, many more processes available to the backyard foundries.

Not everyone is going to be casting heavy pieces like engine parts or cast their own motorcycles. So for those that just want to make decorative pieces you will not be using the same casting process as these heavy duty casters.  For artists creating small scale statues or embellishes and for hobbyists that need a decorative touch to their model plane or boat might want to consider using gravity casting for their needs.

Gravity casting seems to be especially useful when dealing with aluminum and other light alloys. The basic idea behind this casting process is pretty much exactly what the name suggests. The metal is introduced into the mold by the force of gravity. Most other casting process either use natural pressure difference like the kind in certain sand casting procedures or they use forced pressure like in centrifugal casting to get the molten metal into the mold. 

One of the most common uses for Gravity Casting is when permanent molds are going to be used. Also called a die, the permanent mold is really only economical for those planning on using the same mold numerous times and will need to keep the quality at a constant level. While some temporary molds can be repeatedly used the quality of the finished product will begin to suffer over time. What is nice about die molds is that the quality will remain the same over and over. Its a good idea to think of Die molds as a long term investment. Yes, they will be more costly then other molds; however they will outlast cheaper options for molds. Steel, Cast Iron and a variety of other metals are what permanent molds are created out of.

Gravity casting is used for the permanent mold process with pleasing results. Gravity casting is usually used when the finished product is more visually based then structurally based which is why this method is a favorite of artists and even some jewelers. The loss of strength is due to the lack of pressure used in this process. For those that need the strength but still want to use gravity casting, more of the molten metal will need to be used which will increase the weight.

Relying on gravity will take patience, although it will be needed for larger products.

If you have never tried gravity casting then you should, because you just may be surprised by what such a simple thing like gravity can create. For the sake of humor, make an apple and see what happens.

Home Made Foundry, Home Metal Casting, Home Foundry Information

Home Metal Casting

The Do It Yourself movement is certainly not a new one. The term, DIY was popularized in the 1950s but the concept has been around for ages. The concept behind DIY is undertaking a variety of projects either home improvement, restoration, or arts and craft without the help of paid professionals.

Recently the DIY movement has received a boost of popularity with the aid of the internet. Many are finding that DIY projects are easier to undertake with the help of instructional websites which provide step by step instructions and real advice from people who have actually accomplished the DIY process. Several of these sites provide ideas, photos, message boards, and a sense of community for Do It Yourselfers that was simply not available years ago.

Your mind is all you need to set your rules for the DIY projects that you can create. Certainly the most common projects include home improvement such as cabinetry or installing plumbing fixtures, but one of the oldest DIY projects has to be metal casting.

The DIY casting movement has been around ever since metal casting itself has been around, which is quite some time. Really metal casting is pretty simple as you are just taking metal that is melted and turning it into another shape that is needed. Metal casting has been used in the ancient world for the use of making weapons, jewelry, and even religious icons. Metal Casting from DIYers everywhere are used in just about any project and hobby that you can think of. This includes home improvement items as well. Metal casting can be used to make door knobs, cabinet handles, and other such items. For hobbyists, small model parts and miniatures can be created. Even artists use metal casting for sculptures and jewelry creation.

Metal casting possesses the true spirit of Do It Yourself. Many metal casters are drawn to the skill because it provides a cheap alternative to purchasing items or having commercial foundries make custom items. Nearly everything used in metal casting can be made by the caster. The furnace, molds, tools, and many others are made by most casters.

Like other DIY projects, the DIY casting movement is being helped along my communities that are found online. These communities act as meeting grounds for casters to share and exchange knowledge and ideas, not to mention blueprints for furnaces and ingredients for casting materials.

Metal casting is the pinnacle of DIY projects as it involves the fabrication of items from metal. After creating a mold of the desired item the caster will melt down iron, brass, or aluminum in a furnace. The molten alloy is poured into the mold and allowed to cool. The cast is removed to reveal a copy of the original pattern. There are several casting methods so undertaking a DIY casting project can be very involved and addicting.

In the spirit of DIY, metal casters strive to make the best for the least. A great source for aluminum is soda cans and many casters gladly travel to scrap yards for iron or brass.

The DIY casting movement is really gaining steam as many realize how cheap and fun this alternative is.

DIY Casting, Backyard Foundry, and Home Metal Casting Information

Backyard Foundry

The most noticeable item in any backyard foundry is the furnace. This is no surprise really, because without the furnace the entire Backyard Foundry operation would be nonexistent. The furnace can take really any size and form depending upon the need and budget of the metal caster. What really makes home Backyard Foundry furnaces really unique is how many of them come into creation.

Sure there are plenty of companies that will gladly sell furnaces for the hobby metal caster and while this can be a viable solution to your furnace needs many metal casters prefer another method.

Making your own furnace is not as far fetched as it may seem and if you already a Do It Yourselfer, chances are you will have the needed skills and tools in your workshop or garage already. As you can imagine, there are a variety of reasons why people choose to make their own furnaces. The most common reason is fulfilling a need.

Sometimes alot of DIYers will go to a local place to get a part that they need created for them only to find that its way too expensive to make or the foundry doesn't do one off parts. Not to mention the fact that the traditional methods of DIY Metal Casting is quickly becoming forgotten as the industry turns to electric furnaces. So many hobbyists find that constructing their own furnace is an absolute necessity and a great way to preserve a piece of craftsman history. The artisans who use metal casting to create sculptures and other pieces find that making their own furnace grants them a greater amount of control over the entire process. This is actually how many people get into metal casting to begin with.

Lots of times, your first furnace will be very simple and small as you are just getting started. There is really no need to run before you can walk when it comes to something that will be using intense heat and melting iron which can be rather dangerous.

Home made furnaces have been constructed from coffee cans to trash cans or sheet metal welded together. While there are a few components that really should be bought like the retractor to line the furnace walls which should be resistant to high temperature for a prolonged period of time along with special connectors and regulators, most of the furnace can be created in your own home. You should be able to find most of the components that you can not make at hardware stores or plumbing supply stores for relatively cheap.

Along with the furnace parts you will also need to buy a crucible which will hold the metal as it melts along with the appropriate tools that you will use to handle the crucible. When you are at the supply store you may as well get the rest of your supplies such as the sefety clothing, gloves, eye glasses and shoes that are steel toed. There is other safety equipment that you will need depending on the type of work and the type of furnace you are going to make.

Most likely, your first furnace is going to be a simple cupola variation. The cupola furnace which is going to resemble a smoke stack is a simple design and is relatively easy to make for anyone with mild craft skill. This type of furnace will not require a crucible since you will be able to pour the molten metal from the furnace itself into a ladle that can then be poured into the mold.

DIY casting furnaces are a great way to connect yourself with your metal casting work giving you more control. While building the furnace can be complicated at first, once you delve into it you will find the experience enjoyable and fascinating.

CNC Design

CAD Design

First we are going to talk about the initial element of CNC.  That element is CNC Design .  Before you begin a CNC project, you need to have a plan of action.  The design is like a blueprint, you know what you are going to build before you ever build it.

Here are some important elements of design that need to be answered:
What size will it be?
What material will it be made of?
Who is the customer?
What will it be used for?

Your design can be anything.  It could be an industrial part or a work of art.  This is only really limited by your imagination.  Many people use CNC every day to manufacture parts.  Many hobbyists use CNC every day to create art and various home projects.

Before I design I like to sketch a few ideas out on paper.  I like to toy with different ideas to spark my creativity.   This is the equivalent of brainstorming.  When I really get my juices flowing, that is when my best designs rise to the top.  I generally carry around a notebook with me to note designs that I think of during the day.
After I have a few likely suspects, I try to look through each of the ideas to see if I can merge them somehow.  Some designs have different parts or components to them.  Some of these components are better than others.  Can I take some of these parts and add them to another design to make it better?  Just like writing, editing your designs is a critical step in the process.

When you are designing, you are really trying to describe what you are going to build.  The more accurately you can do that, the better the whole process will go.  Just like a house, if you have a strong foundation, you will have a good house.  If you have a solid design, the rest of the process is easy.

CAD
CAD stands for Computer Aided Design or Drafting.  CAD was developed in the early 60s.  Today it is the premier way to design, develop and optimized products.  People use CAD every day to design virtually every product you see.  Generally, designers use CAD to design a product, and then produce prints to manufacture that product.  A print is a picture of a part or assembly that is very exact.  It includes the dimensions and a parts list used to manufacture a product.

Computer Aided Design software packages can generally be broken into two groups.  The groups are 2-D drafting packages or 3-D drafting packages.  Most all software packages are moving to 3-D design.  3-D design is really the next generation of CAD.  Utilizing 3-D design, engineers can make a model of their product.  They can then look over this model for any apparent defects before it is ever made.

3-D Design
Utilizing 3-D design, engineers can cut down on the number of manufacturing mistakes that occur due to fit up and tolerance issues.  This translates into a more efficient operation with less waste for the manufacturer.

Here are some examples of 3-D drafting/design software:
Inventor
TopSolid
SolidWorks
Alibre Design
Rhino3D

2-D Design
2-D design can be very efficient if you need to make a quick part that is not very complex.  You could quickly sketch out a silhouette of an object and convert it into a CAM tool path.  This is an operation where 2-D will really shine.

Here are some examples of 2-D drafting/design software:
AutoCAD
MicroStation

At some point you will need to use CAD.  You will need to take your design and translated it into a print.  The best way to do that is to use CAD.  You will need to purchase a CAD program of some sort if you are serious about CNC.  Many CAD programs have a free or trial period that you can use to evaluate the program.  My suggestion is to try a few and then select one that fits the way you design.

Learn about Die Casting

Metal Casting

Metal Casters have the luxury of choosing between several casting methods to accomplish their goals. Just like other activites, once we find something a caster likes, then he won't change to another type of casting until his needs change and hes forced to learn another type of casting to finish his design. There are a select few groups of people where they really enjoy all the different types of casting and will do a little bit in each casting method. Sure, sand casting might be the most popular but what about Lost Foam or Investment?

What about Metal Casting ?

Die casting is used by industrial foundries and manufacturers to create practically anything and everything, such as die cast cars. Many small foundries, like the one in your garage, backyard, of workshop may find that die casting is really just not economical. But who said that having fun and trying new things was ever economical? The process of Die Casting involves a simple concept. The molten metal is injected with high pressure into the mold or mold cavities. The mold used in die casting can have several small civilities of either the same pattern or different pattern.

The name Die Casting comes from the molds which are called dies. These molds are reusable and are often made from steel but other alloys can be used as long as they can withstand high pressure. The reason dies must be created from metal and not from sand or other material is due to the high amount of pressure used to get the molten metal into the mold. If sand molds were used in a Die casting procedure then the mold would crumble. There are plenty of advantages of using dies in a casting procedure which makes this method desirable for anyone wishing to create a high volume of similar castings.

Die Casting is perfect for anyone that needs to make a lot of the same thing without any quality or pattern deviation. This is especially helpful in certain industries where quantity and quality count. Many hobbyists may have no use for die casting on a practical basis but will often try at least one Die casting for the sake of trying.

There are two types of machines used in the Die Cast procedure. These machines are essentially the same and are called the Hot-chamber and the Cold-chamber.

The Hot-chamber machine melts the alloy and feeds it into a section of the machine referred to as the gooseneck. A piston then forces the alloy into the mold. A separate furnace is not needed but the draw back of this is that metals with higher melting points can not be used.

The Cold-chamber is used for metals that can not be used by the Hot-chamber such as aluminum and copper. A separate furnace is needed to melt the alloy which is then poured into the injection cylinder and then shot into the mold.

There are a lot of reasons that people like Die Casting and some of those reasons are that it is fairly quick and you can repeat the good quality time after time. While the initial cost of Die Casting exceeds several of the other casting procedures, those that need a high number of casts in the shortest amount of time possibly will benefit greatly from the investment.

If you are looking for high volume and repetability which most people are with commercial goods, then Die Casting is what you are looking for. The molds, or dies, used vary in life cycle depending upon the material used to create the die. The die can have one cavity or several cavities depending upon the need.

Everyone should try die casting at least once if they can afford the initial cost. Besides, who knows when you'll need a small battalion of metal soldiers which can be made quickly and easily with die casting.

Considering The Different Internet Connections And Certain Pitfalls That You Might Come Across

The internet is made up of a worldwide network of computers; this can make navigating the internet difficult. Data sharing worldwide is possible through these different internet connections. Many feel that the greatest resource in the world is the internet. This resource offers both business and pleasure opportunities. Different internet connections that are presently available make organization, communication, and research easier.

We will now learn about the different internet connections that are available. There are many options available, three of the most popular, which are available through the phone lines are: cable, traditional dial-up, and DSL.

As modern technology advances there has been an increase in demand for the wireless varieties of internet connection. With all the different internet connections available, the wireless options are now becoming very popular.

Wireless fidelity or Wi-Fi as the wireless internet is known, allows connecting to a network without being limited to a certain location. Wi-Fi is available in public locations, such as libraries, cafes and many hotels offer this service. Verizon and Sprint also offer wireless network as a long range service.

Of all the different internet Connection Set Ups, the wireless option is by far the most painless to set-up. Even people who are not technology "nerds" can understand this technology. It is as easy as going to the computer’s Start menu and click on the Control Panel. This is where the Network and Internet connections options are found. All of the different internet connections available can be managed from here. Next step is to go to network and sharing center, then make sure that you select network option. This allows you to manage internet connections from all wireless sources.

Now that you are in the proper menu, you will see the "Show All" option, click on it and then hit the refresh button. The active network connection that you want to log on to is located here. Choose the option that allows you to connect automatically if you plan on regularly connecting to this network. By checking this option, your computer will be able to find different internet connections and the proper one.

Troubleshooting will be required if you are unable to locate a network. You will first need to find the connect to a network window, next click on network or Set Up a connection. Then click on manually connect to a wireless network, press next. At this time you need to enter the security features and the network’s name.

Problems with Different Internet Connections

Remember if you experience any problems logging in to your wireless internet connection, contacting the service provider is strongly recommended. They will guide you step by step and solve your problem to accessing your internet connection. Generally the wireless option may be the best choice of all of the different kinds of internet connections.

Designing art for CNC

CNC and CAD

Introduction to Design
Designing for CNC is arguably the most important step to the CAD Design Process.  Why you might ask?  Because it is at the beginning.  This is the planning stage of the process.  If you come up with a bad design, all of your work after this point is lost.  I also think of designing as the planning process.  You need an inventory of what you have to work with before you begin.

Every thing needs some planning to start with.Whether it is buying a home or a family vacation.  CNCis no different.  You need to think about what you want to accomplish before you ever invest any time or money.  Now I am not saying you need to have a perfect plan.  What I am saying is that you need to at least have a plan.  Believe me I have had many plans and virtually none of them ended up perfect.  What it did do was give me a guide to follow.  A roadmap of sorts.

You also need to know your limitations.  For example, don’t go designing a metal sign if you have a CNC Wood Router and nothing else.  Or, you want to make a 2” thick wood routed sign, but your CNC Wood Router only has 1” clearance.  You will need to know you own personal capabilities and your shop’s capabilities.  Once you know that, you can improve your situation either through training or purchasing other tools.

Where do good design ideas come from?
First, look around.  Take an interest in your environment and all the various objects around you.  Look at how things are built.  Generally, I don’t look at the overall design.  I try to figure out how they build a specific part or area of the design.  For example a unique latching mechanism.

A lot of good design is experience.  Experience comes from failure as many people have said.  The bottom line is you need to try stuff and experiment with ideas.  Pick the ones that are useful and go with them.  Leave the failures on the scrap pile and move on.  Never marry yourself to an idea as being perfect.  Virtually everything can be improved upon.

Know what you want to as an end result before you ever build
When designing it is very important that you know what you want to build.  You don’t need to know every detail, but it helps if you have a general idea.  For example, the item may need to fit inside a certain dimension.  This dimension could be the size of the box used for shipping the item to the customer.  This is a requirement of your design.  Requirements can either be self-imposed or put upon you by someone else.

Another example may be building a piece of art.  You may want to make the piece out of Stainless Steel because it would reflect the sun and hold up in the environment.  Then you find out Stainless Steel is too expensive and that you don’t have the equipment to work with it.  Stainless usually maxes out your equipment.

You need to have a project plan, or at least a pretty good idea of one.  You will need to take inventory of your capabilities and match your design to them.  You will also need to get all requirements for the project before you ever begin.  If you do that, you will not waste extra time redesigning again and again.

What are the limits?
Really, you are the limit.  You brain and its thinking are the limit.  If you can think of it, someone, somewhere can probably build it.  The more you expose your brain to different things and ideas, the more connections it will draw.his is where your creativity will generally come from.  You need to feed your brain interesting information and it will spit back some interesting designs.

Part vs. Art
In designing for CNC, there are two different paths.  Art or Part.  By art, I mean a design that may have extra embellishments, curves, features, text, etc.  By part, I mean a square with a hole in it.  Or a triangular gusset.  Art is usually flowing or an image of something.  It could also be a sculpture for example.

When you are designing art, you normally keep a sketchbook with your ideas.  You note them.  They don’t have to be perfect, just roughed out.  Sometimes I cut things out I find interesting and put them in my sketch book.  Things like interesting shapes, interesting images or even a unique way to bolt things together.

When you are designing parts, you are dealing with deadlines and customer requirements.  There are no extra things to personalize or stylize the part.  The part is utilitarian and gets the job done.This is mainly what computer numerical control is used for.  This is what various industries use CNC for.

Designing on Paper
Most people scratch out their initial ideas on paper to rough them out.  I like to draw things out in a print, drafting or blueprint format.  This style uses multiple looks and multiple angled drawings to convey what you mean to someone else.  I picked up this style of drawing while working in a manufacturing environment.  Some wood workers will also recognize this style.  Think of a time when you bought “The Plans” to building a birdhouse.

Designing with a Computer
This is what I use next.  Once I have something roughed out, I like to translate it into a computer.  Things are more exact.  You get a feel of the size or how parts fit together.  You also get the benefit of saving your work and coming back to it later.  You can even share your files with others when working on a project.

My Design Computer Setup
A number of people have asked me what my design setup is at home.  Here is what I like to use.  First a powerful computer with plenty of processing power.Be sure to get a lot of processing power, random access memory and a big hard drive.  Don’t skimp here.CNC software will use a lot of system resources and you will save plenty of time by having a computer that can handle that extra load.

Next, buy a dual monitor setup.  You will need a graphics card with a dual output head and two monitors to output to.  Most home users can install this themselves.  Dual monitors keep you focused.  I really like being able to keep my computer screen clean of various design palates that seem to clutter it up.  A dual monitor is perfect for this.

Crucible Tongs Info and Crucible and Crucible Steel Information

Metal Casting

From the earliest attempts to make lead into gold and to the more modern use of making those empty soda cans into a replacement part for that model plane, crucibles have been an absolute necessity in Metal Casting .

Crucibles are placed inside of the furnace where the metal is placed and then melted. The crucible then collects the melted alloy which will then be poured into the model. Since the crucible will be holding metals melted at extremely high temperatures the crucible will need to be created from very strong material. The durability of the crucible will add a certain aspect of safety to the Metal Casting process. Using a crucible that is low in quality can result in shattering, which, let's face it, is never ever a good thing.

Any crucible at any given moment can shatter or fail which is why using appropriate safety gear at all times is so important. In order to handle the crucible which will be red hot you will need to wear boots, jeans, and gloves.  The tools for lifting the crucible from the furnace and then the tool for tilting the crucible so that the molten metal will pour easily into the mold will vary crucible from crucible. Those that make their own crucible will be able to create them in an identical manner so the same tools can be used. Your tools are really what is going to help you lift and pour the crucible so its important to make sure these are safe and correctly installed. You will never want to directly touch a hot crucible, even with gloves.

For those that either can not or will not make a home made crucible can buy a crucible and tools from any of the online stores. A common material for crucibles is graphite as it can withstand the molten metal. Many who cast metal will prefer using graphite crucibles as it can prevent impurities from being introduced into the gold or other precious metal being used.  Another option is the Silicon Carbide crucible.

Silicon Carbide is a great though expensive alternative to the graphite crucible.  A crucible made from Silicon Carbide can handle rougher treatment then graphite so if you are not particularly gentle with your toys then this is a terrific option.

Yet another option available to the home foundry is creating your very own crucible. Many don't really recommend this since commercially created crucible tend to be more durable and will instill a bit more confidence in the casters. It is, however, possible to create a crucible as many of us will at one time or another.

If you plan on creating your own crucible then keep this in mind. There are a few areas of Metal Casting where you should not cut corners, these definitely include crucibles. The crucibles job is the transportation of incredibly hot molten metal which can easily exceed 1,000 degrees Fahrenheit and is really the only thing between you and this metal. The temperature at which your metal starts to melt really determines the quality and material your crucible is made from. Spend that money and do so gladly since it is just a small price to pay for your safety.

Crucibles should only be used to melt one kind of metal. If you have always melted aluminum but decide to try melting brass then you will need a new crucible. This is done for safety reasons. Remember, a crucible is not meant to last forever. Always check your crucible before use to make sure there are not cracks or imperfections if there are then do not use that crucible.

Crucibles come in a variety of sizes and can be made from a variety of materials. It all depends on the type of metal to be used and the size of the job. Never skimp on the price of this tool and always follow safety guidelines and use common sense when dealing with a hot crucible.

Gas Torches, Smith Torches, and Soldering Torch Information for Casting Torches

Furnace Torch

Metal Casting provides the hobbyist with a great way to create personalized parts and pieces that may otherwise be unattainable or far too expensive. Casting is an ancient art that is still is use to this day by major industries to artists to those with backyard foundries. This skill is a valuable one that promises to provide the hobbyist with a rewarding past time. Most hobbyists begin their casting careers with a modest sized furnace to fit their most basic needs. Within a few months, the hobbyist might find that the furnace has grown and that they are casting at every chance that comes along. Don't worry, this is completely natural.

To say that Metal Casting is addictive is an understatement. Your ideas can now become reality with molten metal and metal casting. This is perhaps one of the greatest parts of the entire metal casting process like seeing what was once just sketches solidify from liquid iron, or whatever metal is used. All the metal caster needs is an idea and red hot liquid metal.

The furnace is the pride and joy for the metal caster. Since you are making your own furnace, most DIYers construct it to fit their exact design requirements. Many home Home Metal Casting foundries are based on home made furnaces and if constructed correctly can prove to be highly effective.  The crucial part of the furnace is the furnace torch. The torch brings the heat, incredibly high heat, and without it that chunk of metal would just sit in the crucible and never see life as something new and exciting. Except as a paper weight; a very ugly paper weight.

When searching for an appropriate casting torch the hobbyist will need to take several things into consideration. The size of the furnace, and what metals you plan to use are chief among the considerations. Many casters will use a torch that uses propane gas as it provides enough pressure and heat to melt most metals. If the hobbyist plans to use natural gas like the kind that is provide in households they may find that the pressure is just not enough and the desired temperatures will not be reached. The same is true for Butane. While natural gas and Butane can be used, propane seems to yield the best results. Oxyacetylene torches are a favorite with many casters especially for casting iron.

Price is yet another consideration. While it may be possible to rig a casting furnace it is not always advisable. Torches can range in price from $40 to several hundreds of dollars depending upon the size, the use, and accessories.

Many jewelers are able to use small independent casting torches but when dealing with metal casting in furnaces you will need to use a torch that can be mounted and used in such a fashion. Many think that just because you need a furnace torch you are going to need a large furnace. This is simply not true. A small furnace and furnace torch can produce enough heat to melt aluminum, iron, and a number of other metals. One of the furnaces functions is to help the flame reach optimum temperature and in the case of Reverberatory Furnaces, a furnace torch is an absolute requirement.

Casting torches can be found in some hobby shops and in hardware stores. Since everything has gone to the internet now days, you can see that there are plenty of places online that sell these torches. When buying a torch hobbyist should shop around in order to find the best deal. Always use caution when dealing with a furnace torch.

Silversmithing Tools along with Metal Casting Tools

Metal Casting

Metal Casting takes a certain amount of skill and knowledge not to mention the appropriate tools of the trade. Luckily, anyone can learn metal casting and the tools are widely available and some can even be crafted right at the home workshop.

Most of the DIY Casting tools are pretty standard and can be used for the different casting processes. If you already familiar with metal work then the chances are pretty good that you already have some of the tools in your garage or workshop. In fact, it is possible to make many of the tools that are commonly found in small foundries.  If you are unable to make your own tools then there are many online resources where you can buy tools and even home improvement stores will have the tools.

The absolute must have metal casting tools will be used for safety. Safety in the home foundry is a must since any accidents that can occur will more then likely result in devastating injuries, remember safety first.

Gloves will be necessary when pouring the molten metal or picking up the crucible with the aid of heavy strength tongs. Its important to always practice safety and you will have extreme heat coming from these molten metals so its best to have protective clothing on your arms and legs. Jeans and work boots will help prevent any injuries in case of spills. Remember, molten metal will splatter when poured on wet surfaces or surfaces that have recently been wet. Even concrete can cause molten metal to splatter that is why metal casters always keep a muffin tin on hand where any excess molten metal can be safely stored. Always wear goggles when working with intense flames to avoid eye damage. Without the appropriate safety gear injuries are pretty much guaranteed. 

The furnace is the most important tool of the trade when it comes to metal casting. This tool does not necessarily have to be large and can even be as small as a flower pot. Size does not matter and even the smallest of furnaces can melt your alloy. The individual tools used in the furnace can differ. Not all of them will use a crucible but all of them will use a fuel source and require a refractory of some sort to help shield the furnace and direct the heat.

Simply put, the crucible is the object where the metal goes when you want to start the melting process. It pools inside the crucible and with help of tongs which can be made in a workshop is transported to the mold to be poured. Sometimes you will need a ladle in order to transport the mold if you have a furnace that doesn't use crucibles. The desired shape of the molten metal bascially is caused by the mold that the metal is poured into. The mold consists of two pieces a cope and drag. Cope and Drag are used to describe the mold and the cope is the top part of the mold and the drag is the bottom part of the mold. The sprue is where the molten metal enters the mold. After the metal solidifies the sprue is cut away from the cast.

DIY Casting involves many other tools some of which are used for all processes and some are not. The tools needed change from job to job. When you start out in metal casting make sure you gather all the needed tools before you begin. As you start new jobs or look at doing new projects then you can start o gather more tools in your inventory.

Details on Metal Casting and Casting Patterns

Metal Casting

Metal Casting is a useful skill that has its roots in antiquity. Weapons and sculptures were traditionally created using this method but as the DIY movement gained momentum many modern day casters have found a use for Metal Casting to make plumbing fixtures, door knobs, and many other items. Today, small foundries can be found in many backyards, garages, and workshops.

In order to make a casting of metal, you will need a furnace capable of melting metal alloys at high temperatures. Usually, individual metal casters will construct their own furnace. There are companies that will sell small scale furnaces but they are often costly. The most common type of casting is called Sand Casting which uses sand or green sand to make the molds where the molten metal will be poured into to form the finished product. The mold is a handmade item placed in a flask which has two parts, a cope and drag. The mold is usually made of sand, but can also be created using other ingredients like latex or even metal. It is in the mold that you will set the pattern to form the mold cavity.

The mold cavity will be an impression of the pattern including the fine details which will then be filled with the molten alloy. Pattern casting is an art form in itself, really, but anyone can create a pattern even if you have no artistic skill what so ever. The pattern is an original which will be cast into metal. Common pattern castings include complex engine parts for models, replicas of Civil War era weapons, sculptures, and even jewelry.

The pattern can be made of any material like clay, wood, and wax. The pattern material really depends on a few factors like the casting method and the availability of the material. If you are able to carve wood then you can use this skill to make patterns. There are some casting methods that call for the patterns to be made of certain materials. An example of this is the Lost Wax DIY Casting Method which will use wax as the pattern.

When creating the mold, you will place the original into the drag of the flask and place more molding material on top forming the cope. When the mold is dry you will carefully remove the pattern revealing an impression in the mold.

If you are creating your own pattern you will need to make it with Contraction allowances in mind. This contraction allowance will compensate for the shrinkage that occurs in many casting processes. In order to take out the pattern without disturbing the mold, draft allowances need to be considered as well. The pattern should have tapered edges to allow for easy removal.

Many who make their own patterns will add sprues, gates, and risers to the pattern so that when castled these items will already be in the mold.  These devices will allow the molten metal to find its way into the mold cavity.

If you find it difficult to make your own patterns then you can pay for pattern making services; although many casters in the same situation will just learn how to make patterns to save money. Pattern casting is a valuable skill to have and can be learned rather easily.
