That's really cool! I was wondering when I would start seeing 6+ CIM drive parts show up on CD. It seems to me like you are running chain between the CIMs and the middle vertical shaft, but I don't know how well chains will work at this speed. You may want to consider using belts instead. I know teams have used 5mm pitch HTD belts in place of chain on drive components, and it works out well if the center to center distance is exact. Out of curiosity, where do you plan on buying the miter gears from? Also, what is the thickness of the gearbox plates? It's hard to tell from the pictures, but the lower plate seems thicker than it needs to be.
