Link for one source. There is
another source but these do not seem to be for repair as much as frame building. That is they do not appear as "heavy duty" as the first choice.

I think the side rippling was due to your technique. As you tightened down the block the leading edge pushed into buldged out area ahead and crimped it in. I've never used frame blocks but I'd suggest either a larger starting gap in the blocks, radiusing the leading edge of the blocks or starting at the widest part of the buldge and wrk out in 2 different directions. Starting in the middle would require several passes.
I did not start in the middle as I thought doing so might be too large a change. Ditto for not moving the block too much. I thought it best to ease the tubing back into shape rather than "pop it". The chamfering idea is good if one has the machine tools to do so. It would have been interesting to try several blacks together.
The frame still needs to have the head tube pushed back out. One good thing is the bend in the TT and DT now is gentle and not a real noticeable bulge. Maybe I will have the frame straightened. One concern raised when discussing this with Kurt before the TT "repair" was the TT just giving way. Having been crunched, would it be likely to revert on application of force to the HT? If I could preserve this frame with only a TT refinish, that would be the ultimate goal. But as I said, I prefer not to do another face plant.
