Thanks, this looks exactly like what I'm looking for.

Just a question, what is the difference between "pinion wire" and "spur gear stock"?

Application: As long as the fab rules don't change dramatically and the kit motors stay the same, we may choose to design a planetary stage for the FP motor.

The pinion is 19T (last year). So, with a 45T ring gear, we would need four planets of 13T.

This would give a GR of 64/19. With the FP NL speed of 15000 rpm, the first stage NL speed would be 4453 rpm.

This is very similar to the Chip NL speed of 5500 rpm and the drill + first stage NL speed of 19670 rpm / 4 = 4918 rpm.
