Maybe you could help me create the teeth for a specific pin size and count? This is the part I'm at now.

So I made a great rack, but how to equate the a and b values with how many pins in the roller of a specific size?

I could have those values dictate the amount of pins, but how to create the teeth in the rack per the pin count of my choice? I guess thats just an offsetting value of a single tooth made?

You've gone beyond what I can speak to about it.... Any examples you give would help alot......
