I have a bunch of misc. range scrap ingots that I'd like to melt into a single 500lb batch for the sake of consistent alloy. The cheapest pots of such volume are at Walmart. They are stainless steel but the steel is pretty thin and 500lbs is a lot of weight. I'm thinking the pot would probably do it but what do you guys think? Any engineers here who can tell me how thick a stainless pot wall has to be for enough strength?
