Hobby Metal Casting Knowledge.

Do you want to learn how to cast things in molten metal?

In this day and age of rapidly diminishing practical skills, the purpose of this web site is to teach those who want to achieve independance and have the freedom to express themselves in metal, when we talk to people we hear the same message over and over, most lament the death of the skilled trades person, you know the kind of man or woman who can get to and - make - fix or create something with their bare hands, if you are practical minded, like to build things, and you also enjoy a creative challenge, then welcome to the world of metal casting, you're gonna love this.

You'll be joining other people from over forty three countries around the globe to learn about the art of metal casting, we can teach & share with you how hobby foundry work can be done in your home workshop using self-built equipment & tools.
The basic skills & methods we'll explain to you have been successfully used by many people who have never before tried their hand at metal casting.
Once you understand the basics of this metal craft then the sky is the limit.
You will really enjoy casting metal, there is something magic about watching molten metal flow into a sand mould,

What can I make you may ask? All kinds of things. The only limiting factor is your: Skill - Imagination - Determination - Passion. Foundry work is fairly basic, you'll use a timber or metal pattern to create a cavity in a two-part sand mould, then carefully pour molten metal into the mould cavity. The more you learn about metal casting, the better your skills - creativity & work will become.
People just like you begin casting metal for all kinds of different reasons, the trigger for most is usually the desperate need to remake an obsolete part for a restoration project, and when you think about it, it really makes sense, if a part was originally made using the green sand casting technique, then nine times out of ten, it can be reproduced again using the same technique, this is the kind of thing we teach in our ebooks, using practical methods to recreate metal castings from aluminium or bronze. The metal casting process is not difficult to learn, and once you know how, you are only limited by your imagination.

The image below shows a common foundry moulding medium called green sand, the name has nothing to do with the colour. When a pattern is rammed with well prepared green sand in a mould box, the small grains of sand bond together to retain the shape of the pattern, (foundry sand is not the same as beach or river sand), and when the pattern is removed, an exact shaped cavity remains which is where the molten metal is poured. Other types of silicate sand can be used for making moulds also, but green sand is good to start with.

Aluminium is a great way to begin metal casting, you can melt good quality scrap to make your own ingots, which will be used at a later stage to make your metal castings, good clean scrap can be sourced from: engine inlet manifolds, old Al cylinder heads, cast a Al cover plates, bell housings, etc.
Aluminium Ingots.

To melt the ingots into molten metal thay are placed into a crucible that can withstand extremely high furnace temperatures, aluminium melts at around 700C, bronze melts at around 1200C. Crucibles come in all shapes and sizes. The best quality crucibles are made from silicon carbide, properly cared for, they will last for several years, they will outlast clay graphite crucibles. Some people make cheap melting pots from a short length of heavy walled pipe with a base plate welded on, but they don't last as long.

Most hobby foundry workers build their own Gas Fired Furnace. The Metal Casting Made Easy ebook provides complete instructions. All measurements are supplied in both imperial and metric. The furnace interior is lined with a high temperature resistant refractory cement which can be obtained from foundry supply houses, you can also make your own home made refractory, (an old time recipe is included in the ebook) but it may not last as long as the proven commercial variety.

After preparing the sand mould, and the metal has reached a molten state in the furnace, it is then ready to pour. The crucible full of molten metal is carefully removed from the furnace with a pair of special lifting tongs and placed into a well designed pouring shank, wearing the proper safety gear you take hold of the pouring shank which cradles the crucible and then quickly pour the molten metal into the sand mould. After the metal cools down, the mould boxes can be pulled apart to reveal the bright new art casting - car - motorcycle part, or even a reproduction part for an old machine, the things you can make are almost endless.

When you have become familiar with the methods and techniques of metal casting you will be able to start making your own special castings, which may include parts for veteran & vintage cars, or even the later model classic models built in the sixties. The raw castings below are fresh out of the green sand mould.

The gates & runners are then removed from the castings, along with the sand cores, the cylinders are then prepared for the machining operations, to carry out the machining of the castings, a small bench lathe, a pedestal drill, and some small home made tooling & jigs were used to produce the cylinder as shown below.

Our ebooks have helped many people learn how to make their own vintage car - motor cycle - antique - art castings - sculptures - property name plates - or parts for special projects. The possibilities are quite endless, once you know the basic methods and techniques of metal casting. But you should also be quite aware that dealing with molten metal can be dangerous, unsafe practices can cause injuries. The metal casting process requires that great care should be exercised at all times.

We just love to hear from our customers about the success they are having.The email below arrived recently from a happy customer, we're pretty thrilled to know that Keith was enjoying real success with the hobby foundry knowledge he has gained from the ebooks, you could also enjoy metal casting success.
Hi Col.
Thank you for checking in on me. Also thanks for the ezine.
Good stuff. I actually purchased several books on home foundries
and I am pleased to write that I literally have my furnace behind me,
here in my room with a 100 watt light inside of it to slow cure it.
You see, I just cast the refractory this weekend. I am very happy
with the way it has turned out.
Your design is the best of all of the designs I have found put
together. Plus I added a few of my own ideas along the way.
I will send you a picture of it when it is done.
Thanks again. Keith Taylor.
