Large turn table for posing people?

Question

I want to build a large turn table for posing people for photography. I have one now, but it only works for standing poses. I plan on building one out of a sheet of plywood cut in half. The finished dimensions will be 4'x4' then. Does anyone know any place for plans or at least an idea for a bearing. I was thinking of routering in a round groove in the top an bottom and using marbles for bearings. I need the bearing to be out near the edges so that it still turns under an unbalanced load condition such as the model sitting to one side. The small lazy susan bearings are too small of a diameter to work properly under this condition.

Visit your local hardware store and look for the wheels that you can bolt onto the underside of the plywood. Don't forget some sort of center support too.
