Building a Turntable

[@Dancelook]

Are the caster wheels polyurethane or rubber?

[@OldenGrumpy]

Those were relatively inexpensive ones from Harbor Freight, as I remember, they were a hard plastic with a rubber tread. One of the neat tricks about this design is that with the wheels mounted upside down, they roll against the wooden deck. This is a smoother surface than the floor, quieter as well.

what kind of motor drives this platform?

[@OldenGrumpy]

The motor and controller were a professional unit which we rented. The motor was built into a box (which we bolted to the floor) with a rubber wheel about 12 inches in diameter which ran against the outside of the 2 x 8's. There was an adjustable spring which kept the wheel in tight contact with the wooden surface.
