what

these
acrobatics you mention? <BR><BR>I certainly shim the whip flange in =

90

this: I
notice quite a few of the capstans I've removed were slightly off center =
of the
keys anyway, and not always in the right direction (making the capstan =
spacing
noticeably off). It just seems to make sense to me to take advantage of =
the
opportunity (while drilling new capstan holes) to see where the whip =
heels are
when all the action parts are properly spaced to the strings =
(particularly in
the bass and tenor, where the strings can't be moved) and drill capstans =
off
center purposely in the right direction.<BR><BR>Probably even just some =
form of
eyeballing the relationship of the whip heels to the keys could be used =
to mark
where to drill the capstan holes. I wondered though if anyone has =
thought about
this and perhaps come up with a real accurate way to do it.<BR><BR>I =
also wonder
if there is any reason why slightly off-center capstans could be a bad =
idea, in
terms of geometry or wear. Perhaps more wear on one side of the =
keybushings? I
imagine that would be subtle if noticeable at all.<BR><BR>Any comments =
will be
