I've got a couple old freon tanks, the ones about 3 gallon size. Cut one up yesterday thinking I could replace my old cracked cast iron bucket with it, but I'm wondering if it's too thin. Measured .040 thick walls. It sits on top of the chimney support my cast iron bucket slips down into, lacks maybe 1/4" diameter of going in. Thinking I could either weld trunions to the walls, or drill and install bolts for the same thing if it acts like its going to slip into the chimney under heat and weight of lead.
Anybody using one of these?
