I needed to repair an Exabyte 8505 8mm tape drive which had a broken 14 tooth
approx 3/8 inch diameter nylon gear in the cartridge handling mechanism, and
lacking suitable spares, I decided to attempt to reform the gear; this post
describes the method and results.



Gear sizes are standardized. It would be easier to find the raw
spur gear stock and re-machine the bore and length to suit your
purpose. Check the "Machinery's Handbook" for sizes.


It would indeed by nice to have a variety of standard nylon gear stock
on hand; has anyone found a cheap source for such kits?


http://www.allelectronics.com/ has some but there's such a wide possible
variety that hitting http://www.mcmaster.com for a specific gear (or
two) might be useful.
