My Auttoban book indicates that the natural nesting material of a cue ball would be felt. This would keep the ball from acting like a rolling pin on the plywood. Scott

Perhaps an over design, but I would have opted for a dense, hardwood race with a sculpted bearing surface, doweled to a 1-1/2+" thick plywood platform. Regards, Peter L.
