When I started to cast aluminum the end goal was to build a lathe from scratch following the dave gingery machine shop from scrap metal series of books. Now that I have the lathe, I won't necessarily need to cast large parts all the time, and thus it seemed like a good idea to build a smaller furnace that would be quick to setup, would cool down quickly, and would also be portable. I was initially planning on building a small furnace from a big coffee can, but when in the paint section of a hardware store I noticed new empty paint cans for sale ( for $5 each ), and decided these would be the way to go ( more capacity and I wouldn't have a bunch of instant coffee to drink ).
