I used my bench vise, vise grips and regular pliers. The largest patch was about 4" long. I bent the two 90* bends first, sectioned it in 4 places with the whiz wheel, then pressed it against the bottom pinch weld and molded it into the shape of that curve. Tacked it on and welded up the whiz wheel slots. I worked on it probably about 20-30 minutes at the time and then left it be a while. I cannot just keep at it. I don't have the patience, so I have to do it in steps.
