The picture below shows the pinion from the belt tightening arm on the drill press.
I would like to make a new one with a bigger knob on it. That way it will be easier to tighten the drive belt.
The pinion shaft is 0.750" in diameter with 7 teeth and a pitch of 12.
I have the proper equipment to cut gears but I can't figure out which Involute Cutter I need to cut the teeth in the new shaft. In fact I'm not sure such a cutter exists. All the charts I reviewed don't list a cutter for less than 12 teeth.
How would you make the teeth in the new shaft?
