[TowerTalk] TIC plastic gears

[john at kk9a.com]

Good luck with finding one. There are many gear suppliers online but buying
a small quantity is challenging.  I would try McMaster-Carr.  Maybe another
option is 3D printing if you have solid modeling software. Make sure that
the plastic gear is tight against the rotating shaft to prevent slippage and
wear.  I put a screw in the side of my housings to keep the potentiomenter
bracket in position.  About a decade ago I needed a couple of the steel
gears that fit on the 10mm windshield wiper motor shaft and was unable to
purchase them, at least not for an affordable cost.  I wound up having to
buy gear stock and machine them myself on a lathe.

Does anyone know of a source for the small plastic gear that fits on the
multi-turn pot inside the Tic-Gen ring rotor motor box? The one that lost
some teeth
had 55 teeth, was 7/8 inch OD and had a metal insert to fit the 1/4 inch
shaft of the pot.  I have a replacement from the pot removed from a
slave motor which didn't need the position indicator, but I would like
to have a replacement for just in case.  These motors were late 1990's
vintage, with the sheet metal box, and the 1022 size ring.

I don't want to have to go to the external pot assembly TIC-Gen uses now.
