 I got a job in on this fine old Rivendell with a dented top tube.  The nature of the dent wouldn't allow it to be just filled with bondo because of high spots in the deformation.
 So I took the appropriate precision tube block from Paragon Machine Works (not related) and slowly clamped it down after applying some grease.  I would tighten, rotate and repeat a number of times.
This pulled down the high spots and removed all but about .010" of the dent.
 Then, I laid down a puddle of 56% silver at very low heat.
 A little filing and sanding and it is as good as new.  Ready for powder coat.
The goats were benevolent and I will be replacing the bar end shifters on the new rain bike with these Retro-Shift (again, not related) units.  IMHO they are the ideal rain shifter.

  1. It's great to see an expert work on my bike frame. Can't wait to see my frame after the new paint job is done. I will do my best make sure the wind doesn't blow it over again. Thank you Neil.
