However, sometimes I don't like using 12 tooth 20DP gears because I believe they are undercut. Not a big deal really, but I just feel the 14 tooth gears mesh a bit nicer. I really wish we could get a bigger boss on the face of the CIM, like 1" maybe.

Also, for the pinions, which see the most cycles of operation, I like to use Martin S20XX series gears, as they're slightly harder and I've experienced some odd wear issues with the AndyMark pinions. Of course, if I wanted to I could probably harden the AndyMark ones.
Could i get a link to the gears you like to use
