This would likely be a custom part, but you can definitely do press-fit CIM pinions. I prefer press fit to keyed pinions personally, whenever possible.

Otherwise, Loctite or something would probably hold on. I wonder if you could even put a snap ring groove into the output shaft of the motor?

I just remembered this:

15t 32p press-fit for a CIM shaft. If you switch to 32p on your first stage, that's doable.

Good to know.

Yes. This is what I originally planned to use, but I could not find a good 32dp mating gear. The WCP ones only come in 20 and 40 tooth, which are not great sizes for this.
I guess I could look into modifying a SDP/SI gear, but I wanted to keep machining work down on this design.
