Nice work.

I see 29 teeth.
That is nice, it is a prime number; and unless the other gear has the same number of teeth, it will prevent unequal wear.

Teeth would probably have been done in cormier (sorbus domestica) which is a very dense wood.

edit: I see you have Guaiacum, which is even harder and auto lubricant.

The teeth are from “azijnhout” also known as “Steen eik” and the theet on the wheel should when you divide them never give a round number. That’s for wear as you mentioned. Guaiacum was never used as theet only as bearing surface.
