Last week I posted a question and got no response so I'm going to try one last time. So now that I've got you attention:

Does anybody know what the tooth profile is on the final gear in the Fisher-Price gearbox?. The best I can measure the pitch is 14. But what is the pressure angle? It looks to be more than 20deg.

The first person with a correct response will recieve, absolutely free, a custom encoder gear to use as you see fit. Correctness will be determined by the mesh of a fabricated gear with the FP gear. Partial credit if you can tell me how to figure out what the pressure angle is with a pair of calipers and not much else.
