Pressure angles for motor pinions
In all the data I've managed to find on the motors in the kit, the pressure angle of the gears often seems to be missing. I know that the Fisher-Price pinion and the smaller diameter part of the brass gear for the Chiaphua motor are both 32 diametral pitch, but what pressure angles are they (20 or 14 1/2 ?)
