In this tutorial I am going to show you how to build a simple and effective forge.Using this forge I was able to heat steel hot enough to easily shape it and I was also able to melt aluminum.
Teachers! Did you use this instructable in your classroom?
Add a Teacher Note to share how you incorporated it into your lesson.
Step 1: Materials
For building this forge you'll need some rocks,I used granite,a bucket of mud,and a iron or steel pipe and yes I do know that the pipe in this tutorial is galvanized and that heating galvanized metal is bad,but to counter this I coated the pipe in a layer of mud and I use this forge outside so it is well ventilated.
Step 2: Construction
Put the rocks in a ring.You can make it any size you want but I would keep it small to get maximum heat.
Step 3: Construction Part 2
Next you want to coat the inside of the forge with a thick layer of mud.Coating it with mud will insulate the heat from the ground so the ground doesn't absorb it and the mud also insulates the rocks so they don't crack.
Step 4: First Fireing
Here is the lit forge.To get the fire hot enough i connected the metal pipe to a vacuum cleaner on blow.I am heating up some steel to test how hot it gets ,and in the can I am melting some aluminum.
Step 5: It Gets Hot!
As you can see the forge reaches forging temperatures it was also able to melt aluminum .
Step 6: Conclusion
As you can see I have upgraded the forge a bit and made it bigger.but anyways thanks for viewing and since this is my first instructable please comment and tell me how I did.
