paper: Easy to convert Screw-driver Gear-boxes

[IKE]

I just got word that be careful trying to press a FP into the pinion coming out of the Bosch unit. Although it is an RS550 motor in the unit, I was told that trying to press the pinion on a FP motor has resulted in broken pinions. My guess is these pinions are powdered metal and heating them up before pressing might help get a fit that won't brake them (this is a guess and has not yet meen tested).

Hopefully someday in the future we can just use a unit like this without having to swap the motor.
