I'd appreciate any recommendations and insight from experienced wheel
builders on this subject.
A couple of years ago I built up a new rear wheel on a well-used Campy
Record hub. The spoke holes in the flanges were slightly enlarged
(elongated) from prior use.
I used new spokes, took care to lace the wheel in the same pattern and
orientation, tensioned and stress relieved properly, etc. Still, I've
had three spoke failures (one DS and two NDS), roughly one every 2500
miles. I've never broken spokes before on one of my own wheels, and
assume it's because the heads have more room to move in the flange
holes and thus fatigue.
I've read about using small washers under the spoke heads to solve this
problem. The question is, WHAT KIND OF WASHERS TO USE, AND WHERE TO
GET 'EM? Someone suggested pop-rivet backup washers, but the common
1/8" size doesn't seem to fit a DT or Wheelsmith spoke head quite
tightly enough. By eyeball, I'd guess the ideal hole size should be ~3
mm, but I've had no luck finding washers near that size.
Thanks!
