Has anyone made there own smelting furnace and how did you do it?
I just need one to start my own mini casting house (my garage to be exact). I want to run it on gas and be hot enought to melt copper, brass , and aluminium. but only on a small scale to make castings for projects i have in mind. I know how the concept works but does anyone know any good tips eg what materials, how hot do it need to go, safety, and anyone how has expience in castings, making them or both.
