[DPRG] Inexpensive gears

On a related subject, can someone explain how to properly measure the 
pitch of an existing gear so that one might easier locate mates for 
them? I have some really nice small motors with 7 tooth gears of what 
looks like approximately 32 pitch, but I'd hate to order a bunch of 
stuff for them that didn't quite fit.

A few people suggested sources of the proper gears, but failing those 
avenues, you might consider getting these servolink gears and machining 
the hub flange off. I have done this with RC model airplane wheels in 
order to adapt them to various gearmotor shafts. With a little planning, 
you can probably produce a jig that will simplify the machine work, 
reducing the chopping of 100 gears to maybe not such a tedious job...

to say the right thing at the right time,
but also to leave unsaid the wrong thing
at the tempting moment.
Sooner or later, when your big chances come,
You'll look for the catches; there'll be none.
