Making a reuseable mold for an at home foundry and casting aluminum?
I've been really interested in at home aluminum casting and wanted to make a forge and try my hand at it. Before I started I've done a lot of research and video watching. It seems it is most popular to use the lost foam method. I was just wondering if it would be possible, and what materials to use to make a simple reusable mold. If I was to cast 10-12 of the same object it just seems easier to make a mold then forming and shaping 12 pieces of foam. Since I'm just getting started i wouldn't be casting anything too complicated or big. Thanks in advance!
