Abstract
An apparatus includes a base, a table rotatable on the base, and a plurality of arms extending above the table's top surface and extending laterally for supporting differently sized cylindrical objects above the top surface. An adjustment mechanism simultaneously adjusts the arms rotationally, such that the ends of the arms can be automatically adjusted to support any one of the differently sized objects without further change. A controller is programmed to automatically control the adjustment mechanism. The adjustment mechanism includes a center gear connected to planetary gears on each of the arms, and a center shaft that extends upwardly through a tubular drive shaft, the center shaft being movable between a lowered position where the arms are locked to the table and a raised position where the center gear is fixed to the base such that the arms adjust position when the table is rotated by its drive mechanism.
