The most interesting post on the subject last year was the first : it was just a mounting for the cluster gear, so it would mesh with the motor shaft. From there, you make up your own procedure.

Probably the most complicated "Atwood" gearing was our system, in which a a larger hole and a keyway were EDM'd into the gear, and the gear was placed on a splined bushing a la change gears in a lathe, and the other gear on the bushing meshed with the main gear in the transmission.
