I always had a feeling metallurgy was one of the dark arts.....
As for the shim idea, it sounds reasonable to me at first glance, but I have not had a chance to take a close look at the fit of the motor and gear. I think it would be relatively easy to figure out the shim thickness required, although you'd have to pull the gear off the motor shaft to install it, or change it if it's wrong. Also putting the shim there would be best from the viewpoint of having full gear tooth engagement. Adding the shim in the second stage planetary would allow partial sun gear/planet gear contact.
