9815/9825 Capstan

Many years ago I made this page:

http://www.series80.org/Articles/capstan-repair.html

with info on the capstan repair for the HP-85. The same fix applies to the 9815, 9825, 9845 etc machines since they have the same (mechanical) design for the capstan.

Also have a picture of a capstan with whats left of the original capstan coating and I use that to calculate the approximate thickness.

When you insert the tape, there is some play, so the dimensions need not be exact.
