The drill pinion is a 0.7 Module gear (module=mm of diameter per tooth) with 12 teeth (not easy to find module, PIC Design has some, Stock Drive Products has some plastic (yuck!) .7 module gears for sale).

The Fisher-Price is a 32 D.P. gear (diametral pitch=number of teeth per inch of diameter) with 16 teeth.

Both gears are not exactly standard gears but are close enough to run with standard gears (in my experience).

As to the Globe, I have never taken one apart. In my opinion, this is the most robust of the three transmisions discussed and I would not mess with it if I were you. The only thing that I do recommend is that you support the end of the shaft as side loads will not only reduce life, but will also reduce output.

Good luck.
