Thank you.
I assumed I would need to support the module at the bottom and the top. What I was especially curious about was where you get your delrin, how you mount it to the rest of the module and frame, and if you use small bearings or rollers around the arc to lower friction. I can see how the top bearing would work, seeing as it is a smaller radius.

Another decision i have to make is whether to have one CIM + gearing within each module or to use miter gears and transfer power through the pivot(using outside gearboxes and a sprocket.) The price and inconvenience of mounting the CIM inside the module points me in the other direction, but I was wondering whether one miter gear rotating around the other while they are spinning at high RPM causes problems. I guess now that I think about it it wouldnt really matter, you just need to make sure that your pivot is very precise so that your miter gears maintain good mesh no matter what angle the one that rotates with the module is.
