Thanks ..
That helps.
1. The hub measures about 11mm so I should be able to get a 10mm
bore hose on (warm it up a bit might help) .
Yep.
2. What type of glue is best?
I use 2k but in
the past I used PU-glue, both works fine.
3. You can see how thick the old one was but yours
seems a little
bigger?
It's important the tape cassette presses both switches but doesn't reach the
bulkhead (right name?).
The tape cassette is spring loaded and needs a little room to move (<1mm).
Put an tape without cover (just the ground plate) in the drive and you can
measure the distance between the drive wheel and the capstan ad a little
(about 1mm or less) and got the thickness of the rubber.
There is enough tolerance in the electronics, so you have room to
experiment.
4. From what I have seen on the list the actual
outer diameter is
0.625 inches.
I calculate that as 15.9 mm, looks good to me.
