A 24" North Star Slab Roller with "wings" of plywood added to each side to make a tabletop surface when layed down. The plywood is mounted so the top of the plywood edge closest to each side of the roller unit is level with the top surface of the bottom roller. In these pictures the gentle slope from the ground up to the roller unit reduces possible stress to the clay, although you can also add supports to the underside of the plywood's outside edge to prop it up to level if you choose. Hinges and metal rods on each side allow the plywood to fold up together for easy portability, aided by the hand grips cut out of the plywood. This configuration fits easily into the trunk of medium to large vehicles or even in the back seat of smaller cars. TIP: This modified, portable slab roller still needs space for a handle to hang down below the surface a little. This is designed to be used on TOP of a table, pulled toward the front edge of the table so the wagon wheel handle extends below the table surface.
