Here's the formula for the tpi of your gears.

From your pic, I'm going to number (letter) your gears.

A: 32
B: 64
C: 42
D: 91
E: 86
F: 21
X: 0.94545
Y: LS TPI (8 in your case)

(B/A) * (D/C) * (F/E) * Y * X = TPI.

A word about X. X is the Kludge factor since the 32 tooth gear isn't spinning at the same speed as the spindle. X is actually 32/S with S being the number of teeth on the spindle's gear.

I haven't looked at the XLS that Dallen posted, but one thing you need to take into consideration is the distance between the lead screw gear and the 32 tooth stud gear - it could be that they don't mesh or they don't fit.

I'm pretty sure I have my math right, you'll wanna double check it.
