Hello I'm knew to the fourm and knew to blacksmithing. I am however a professional welder/fabricator. so I decided to build my own forge. however I was limited on my budget so I have a straight burner made with black steel 3/4" to 1 1/4" flares and brass fittings with 1/16" hole for propane flow, and a 18"x9"x6" hot box. now here is the problem my burner works great when it's not attached to the forge, but as soon as I attach to the forge the blue torch flame disappears and the forge starts backfiring almost. to where it burns and then like sends out a blast of air every couple of seconds and if I increase pressure in just gets faster anyone have any advice?
