1. I have a Ram to build. it gave me this

22 teeth

20 degress STUB-12P

I know there are 22 teeth and 20degree angle but the 12P I don't get?


New member
12P is 12 pitch if you grab hold of a drafting book you will beable to find a table of the involute profile on the teeth so you could draw the teeth profile. You will also beable to get all the equations on how to calculate the dedendulium and addendlium, working depth and so on.

Sorry for the spelling

hope this helps
