I need to fix the warpage issue on my somker. When I was framing out the door I didnt get a good bend on the flat bar on the arc of the tank, so when I tacked it into place their was a slight gap at the bottom but not bad. So then I welded it completely on and the gap grew. Well I decided I would just use clamps and it would not be that big of an issue. Then I did my burnout and it really got worse, about 1.5" at the bottom. I know I can bend and shape it back if I had an oxy acetylene tourch but i dont. My question is since i was wanting to get one anyway to start my basket can I use a brush burner to get the metal hot enough to bend easily? I need to heat a decent size area to get it shaped back into position. The flat bar is 1/4 inch and the tank is a little under 3/16. The one I was looking at is at the Big Orange Store for $50 and is the Lincoln Electric Inferno it has a rating of 500,000 BTU. Any advice would be appreciated before I purchased it. Thank you
