Let revise what I had previously said. I want to build a propane or electric foundry. Mostly I can't stand coal or charcoal. Though I can make it, Smoking is a hobby as well. I am used to playing with gallium and such. Just a little expensive to get. I have tons of aluminum, tin, and iron around here. Which is why I want to be able to eventually build up to able to do iron.
Would it be better to build it into an old stove or build it in an old drum I have cut in half? Of course, I am planning on getting plenty of firebricks. If I build propane do I need an Airflow like with charcoal. I have an electric leaf blower, is that too much or is an old hair dryer better for such things?
A lot of my knowledge comes from reading and Grant Thompson and TheBackyardScientist. I am trying to get information together so I can start making my design.
