Thanks Ed. Do you have/know of a set of general plans to build such? I found this one Don Fogg did some time back but it doesn't say what pipe diameter, or "how" the propane is introduced. I take it that there's a mig tip dumping in the center of the pipe?, or is the propane introduced at/under low pressure?
