Counting teeth on a gear without Gear Pro

[[Ja...]]

So we have a small 96 tooth gear (1.063" O.D.) that we have to machine for our customer down to 33 teeth with some other modifications.  Is there anyway to count the number of teeth without GearPro?  We have Curve available as well.

You can experiment with the "Waviness" Characteristic.  The harmonics should show "Undulations Per Revolution" that equal the gear teeth.  (Set a lower limit to <10 and the upper limit to roughly two times the expected number of teeth)

Is there a link or anything to help with creating the WAVINESS characteristic? 

 

Do I just create a circle, or do a 2D/3D curve?

 

Here is the part in question:

I'm not sure if it works with curves, but it does with a circle. Ive not tried it on a partial circle but had success counting the number of knurls in a circular knob

The problem I have with a circle is that if I don't start on the top of the first tooth, then the probe will jam up against the side of the first tooth and alarm out.

here's a powerpoint that helped me figure out an alignment for locating the first gear tooth.

I was using a probe that was absolutely gigantic compared to the feature, I cheated a bit by not being able to fit between the teeth
