Thinking about doing one of those. The pot I have holds about 45 lbs and it's a little small for alloying. I'm guessing a propane tank about 7" deep would hold 100+ lbs and that'd make things a lot simpler. My thought is 4 angle iron legs welded to the sides of the pot at a height to set over my furnace would do the trick. Can't weld so wonder if that'd be sufficient strength-wise or is it also gonna need braces between the legs? I'll just use my dipper to fill the ingot moulds. Any ideas or thoughts on this?
