I've seen threads where people take a sheet of marek or aluminum and basically bolt it to there Lee pot to lay lead or a mold on to preheat or out some amount of heat into. I was thinking of doing this as I tried running two molds this week and I wasn't having much luck setting the mold on the rim of the pot and having it stay there. I should have a sheet of 1/8 alum large enough I couldn't cut the hole for the pot and screw it down so essentially I'd have more surface area on top of the pot. Has anyone noticed any unexpected effects in doing something like this. As in it takes more heat input or the stand is too flimsy to hold two cavity steel molds and a 6-7lb lead Ingot? Or anything else I may not have thought of.
