The wire wheel specialists I've known don't bother with the spokes when
rebuilding a wheel--e.g. when replacing a worn center hub--they just cut the
old spokes out with a bolt cutter. It's a labor intensive job, and the spokes
are a relatively small part of the cost.
----- Original Message -----
True enough. Trying to true a wheel that is even mildly flattened or more often
potato chipped seldom succeeds, leaves an unstable wheel because some spokes
are loose and that is unsafe because some spokes are overstressed. I think MWS
will shorten pre-existing high quality butted spokes as needed. So, if the rim
is reasonably circular, perhaps the long-term solution is to relace the wheel
with new spokes.
The problem with trying to true the old 48 spoke wheels is that the nipples
seize on the spokes after 60 odd years and it is virtually impossible to free
up the threads to save the spokes which are just not available for these really
early wheels .... also the actual rim itself is often a little distorted and
straightening that is very difficult and cannot be achieved by simply adjusting
the spokes.
I had heard of people deflating the tire and rotating it 90 degrees on the rim
then checking again so I gave that a try... There was no measurable change
although I tried it in all 4 quadrants on the worst wheel ... I suspect that
modern tires are made pretty accurately.
Regarding the "scalloping" I actually made 4 cuts on each tire and managed to
position the blade to cut the tread fairly much like the original profile..
After a 10 mile run the tires look just like they did when before the
treatment.

You probably want to run a little under-inflated as well, to compensate for the
width-wise scalloping of the tread.
