Again for TU58s, since they have shaft encoders on the
motors, you
don't have to have *exact* replacments, but as it happens, the standard
I don;t follow that. Surely the shaft encoder on the motor spindle will
get the motor speed correct, but if the roller diameter is different, the
tape will move at a different speed. Whether that matters or not is
another matter, btu the shaft encoder won't correct for that.
[...]
As I've heard, if you have some refurb material
that is barely too
large, one way to reduce things is to freeze the roller material
with Dry Ice or Liquid Nitrogen and turn the frozen rubber on a
lathe, but I haven't tried that personally.
I;'ve not tried it either (no easy way to get the materials), but I was
told that if you get it too cold (liquid nitrogen, for example), the
rubber goes very brittle and 'machines like glass'. It's supposed to be
easier to machine it at dry ice temperature.
