Charley,
Here is the MOW for your 64 NDP worm, 4 starts:
.21394 max (based on 0.00 backlash)
measurement over (3) 0.02700 pins
I emailed you a response to your questions about CPC-HOB.
BTW, CPC-HOB doesn't do worm threads unless your machine is capable of it, and the number of starts is rather large. CPC-TM is available for setting up Thread Milling machines. That's where the MOW above was calculated.
Do you have a thread mill?
