A propane blacksmith's forge. Made from a old Oxy Acetylene gas cylinder. Lined with ceramic wool. The burner is a version of Ron Reil's Reil EZ-Burner that I made. Below are movies of the forge running: You will note that the burner is offset rather than straight down. This offset was recommended by a number of individuals, the idea being that it would cause the flame to swirl. I have not found this to be the case. Instead, it just causes a hot spot to one side. I would not do this again and do not recommend it. My next forge will use a top down mounting of the burners.
