If you're interested in making your own metal forges, then here are some tips that might help
First of all, you'll need to know how to use a forge. The first thing you want to do is heat the metal up so it's hot enough to melt. Then place an object on top of the metal and let it cool down. This will allow you to get a good idea of what kind of shape your project needs before actually forging it
Once you've determined what shape your project needs, you can start forging it out using an anvil or vice depending on what toolkit you have available. You'll want to keep an eye on the temperature so that it doesn't get too hot or too cold and cause problems with the material itself or with your tools
If your project requires more than one piece, then make sure that they are all made at the same time with the same tools and materials so they will all fit together properly when they're finished being forged.
