That's a good point; I hadn't thought of it that way. Looking back on it, the whole clamping mechanism is a cool gimmick, but not something I actually need... I could also reduce the weight somewhat with other constructions I think.

What I can't gather from this picture is how the primary bearing setup would work. Could we get a cross section view, or an explanation for that?
Thank you!
The bearing setup is definitely an oddball one. Here's a link to the 2015 Offseason folder with the CAD, if that helps:
https://workbench.grabcad.com/workbe...1Z2b-tQWAq3gUh

Essentially, a plate is screwed into the CIM and firmly attaches to the inner race of the 6711 bearing. The outer race of the bearing is pressed into the 64t turning gear and captured with the flanged buttonhead screws seen in the picture.
