Setting face width

HI,

Basic newbie question. I am trying to create an escapement (lever and metric measures) but I cannot find how to set the face width to the value of 2 I want. Instead it always generates as a default of 5 - how do I change this?

Thanks
Chris

Epicycloidic gear 4th axis output

Hi Art,

I am probably doing something dumb but I would appreciate some help. I am trying to cut a 0.6M epicycloidal gear 72 tooth - no spokes.

Any suggestions ...

Re: Differences between gearotic cutting and Thornton
