I keep meaning to try flame polishing but just have not done it. Until watching this video that is. I had an old brass torch much like the one in the video. It was my father's and quite old. I turned it on and lit it a couple of times in the past with no problems. I practiced on a junk ramp and it went well. Very well. I cleaned and polished my JP ramp then went to the garage to flame polish it. I lit the torch and in two seconds it burst into a fire ball. I set the ramp down and quickly rolled the torch to the center of the garage. It lay there with a 1 1/2 foot ball of fire around it for 20 min. Tank and all was engulfed. Nothing was hurt or burnt. Not even the ramp. Scared the crap out of me for a second though. I'll be going to Lowe's today for a new one. Anyone want to buy a torch?lol
