Now if'n you'd listened to me that wouldn't have happened
. Forget this clamping business. No way to judge what if any correction takes.
Now reheat the area you was working on, wedge it somewhere where you can get some leverage, and bend past straight (if you didn't get it hot enough you'll see no movement). OK, pull it out (however you have it wedged) and make sure your correction is PAST straight, somewhat. If it is, wedge it back up, and move it back to straight. Now it'll hold that correction. .......Art B
