Finally tried my hand at a shrinking disc. Seems the going rate was $30-$60 for bought ones or many just make their own. Thought I'd try to make one. Used a piece from a chicken feeder I bought at the farm supply store for something like $3 and change. Drilled a hole in the middle for the angle grinder and voila.
Had a hard time believing it would work very well. But wow. The shrinking disc is almost like magic. Some of the warps in the metal from the heat from welding came right out easily. Getting the area around the welds flat and smooth was a bit more challenging. Especially on lap joints. I had heard they were stronger but they failed to mention using the hammer and dolly go get the joint flat afterwards is way harder :-)
Anyway spent some good time on the RH rear fender. I had seen a video where the guy used a marker to cover the area then lightly sand it to show the high and low spots. That worked pretty well though a wider marker would be good. While not perfect it is much improved. I'll put it aside for now and work on something else.
