C1-10P 12" Lazy Susan Bearing Drive for Dome

This is a ring gear and pinion gear design for a 12"lazy susan bearing I am using on my timber frame C1-10P build.
Some holes will need to be drilled into the lazy susan to fit the ring gear on to, and it is held in place with m5 bolts.
here is where I got my bearing, but they can be found on Ebay and similar sites

I used this motor and motor driver on 12volts and it is working great:
