I was thinking to re-use the motor shaft with the gear hobbed into the end of it but then I have to make a housing about 6-7" long to house the motor armature. I dont want to destroy the motor as I may want to put it back together some time and use is as a drill again. That is why I was trying to figure out what kind of gear this is so I can just put a stub shaft onto my stepper and make a adapter plate to hold it all together.
The thought on it being a metric gear I dont think would be correct as this drill is from the 1960's. I dont think they used metric gears back then.
I am thinking of pulling the head apart and measuring the mating gear and the motor gear to see if from the 2 I can get the numbers to point more to what it is. The pressure angle, I think, is going to be hard to figure out though.
