That is a really nice looking piece of equipment. I like the way the base ring acts as an outer sleeve to channel the heat around the whole lower portion of the pot, rather than just having the flame impingement on the bottom. I've thought if I was to build another pot I would do something like that.
How are the ingot moulds made? It looks like you formed heavy sheet into a channel then welded walls on each end? That's a lot of cutting, forming and welding, and it has to be done right. If the beads have too much texture or any kind of rollover the ingots stick on them. Ask me and my hobby-level knowledge of welding how I know.
