You can 3d print a mount/holder as well. Probably can skip the holder, we've pressed them on free hand before as well. But we got to a point where we were pushing on 30+ pinions a season and didn't wanna bend any output shafts.

Do you happen to have any pictures of this machined holder? We have been pressing on pinions free-handed for the most part, I am curious to see how your mount helps with the process.

Why not just use a 1/2" Hex versa-planetary with no reduction? The tolerances will be much better and you'll have the added bonus of standard mounting holes.

True that you could definitely do this, but if you are going through the trouble of building a custom gearbox, why add extra parts when you could just put a gear on the motor shaft and skip the extra weight/space/added friction (friction is minimal) of a 1:1 COTS gearbox?
