To add a recent experience of mine, I recently rebuilt
a Cipher 540 QIC
drive (in a Ridge32).
The ID/OD of the capstan wheel on this drive is (roughly) 31/64" ID, 5/8"
OD (i.e. the inner diameter is JUST a shade under 1/2"), with a thickness
of 1/4". I found some 3/32" thick square o-rings with a 7/16" inner
diameter and 5/8" outer for $0.10 each (from http://www.theoringstore.com/)
and I ordered a few -- the inner diameter is a bit smaller than required,
but I figured it'd just make it stay on better (well, why not for the
price...)
Hmm, I wonder if an Amphenol neoprene cable bushing might provide a
source there. You'd want to stretch it a little, of course.

Cheap enough.
