Re: Wheel Truing Tutorial

I hope the group finds this week's wheel truing tutorial useful. I
tried to cover all the aspects of truing without running overtime. I'd
love to hear what you think...

The lubing idea at the rim (or eyelet)/spoke interface is good, if
there isn't already fresh lube at those interfaces; but I think it is an
over simplification to expect no rotation of the tensioned spoke with or
without lube at the nipple/spoke thread interface. You need to address
how to deal with the spoke turning by some method of overshoot and
back-off (some use white-out or a Sharpie to mark untensioned spokes for
a reference)or removing tension from the area by rim manipulation so
wind-up doesn't happen.
Your approach to correcting for lateral or radial errors is too
generic. Plucking the spokes in the area of interest will let you know
which one(s) should be loosened or tightened to diminish the error and
come closer to getting spoke tension balance while improving the true.
Crossing spokes and spokes at 180 degrees are changed the most when any
tension change is made.
Side loading the wheel in steps with careful but significant force will
help stabilize the build as well as temporarily unload the down-side
spokes such that if there is any residual wind-up ... it will be
removed. Barnette's method of stabilization works and also does a good
job of stress relieving.
Using tone as only a relative indication of spoke tension as different
gauge spokes will have the same tone with significant difference in
tension.
Use of a truing stand like the Park TS-2 that looks like what you used
in the video is a good idea. The feelers on that stand can be
positioned to indicate both lateral and radial true at the same time for
viewing results and needs for adjustment.... as each any spoke nipple
adjustment will change true in both directions while also changing
tension.
I have considered putting out a video with similar objectives but each
time I write the scipt I decide it needs revising.
