It occurs to me that for recovering tapes with problematic feed holes
(which are used for clocking, even if they are not used for feeding),
the ideal would be an optical reader, which fed via a capstan, and feed
at a good, *relatively* constant speed (or perhaps even via a stepper
motor).
One could then use the data itself along with the clocking from the
sprocket holes to recover the data, even for stripped or tapes with
uneven holes - perhaps with some manual assistance. One could save
timing information from the data holes AND the sprocket holes for later
processing, analysis and recovery.
But for any one person, probably more trouble than it is worth. I have
a few tapes with bad sections, but those could always just be edited and
fixed manually, after reading in the whole tape.

After thinking how nice it would be to have the
ABILITY and tools to

a sprocket wheel, I realized that it might not be truly necessary.
