I'm thinking a machinist could make one, but it would likely cost, a lot. lf I had that problem I think I might make a master out of wood (separate pieces, then glued together), then try casting one out of plastic, or aluminum or brass. Hmm, just struck me, I'm almost willing to bet that there are gears out there, being used in different tools, in just the sizes you need - but I have not a clue where to start looking. Sorry, best I can come up with.

.....Call me a craftsman, artisan, or artistic, and I will accept that. Call me an artist and you will likely get a quite rude comment in return. I am not a @#$%ing artist.
