Skywheel Ride - no motor

This is a model of the Chance Skywheel I built summer of 2015. It recently underwent surgery to accommodate the 12v electric motors I bought. Unfortunately for it, I robbed its motor to power the new Big Ball Factory set I just bought!

The principles used to make the wheels turn are the same in just about every carnival ride I've built. I may make something showing exactly how if anyone is interested.
Uses micro chain to drive the wheels since classic chain was too wide to fit under a grey rod base.
