After lots of work I have tried my new bottom pour propane pot for the first time. Thanks to Kenjudo and Maximilian225 for there tips and help. I still have a few bugs to work out but they are minor. Its a 12x12x12 pot with a 450# working capacity. The burner is a 160,000 BTU unit that I got from a place in TX with 5ft hose and regulator for $40. It works like a dream.
