  • Patent number: 8309014
    Abstract: A rotatable turntable tool is used in trimming wheel-thrown pottery. The turntable tool includes a base portion, a bearing member, and a cap portion which is rotatably attached to the base portion. A method of trimming an unfired clay workpiece includes steps of inverting the workpiece and placing it at a central portion of a wheel head on a potter's wheel; placing the turntable tool on top of a central portion of the inverted workpiece; pressing downwardly on the cap portion of the turntable tool while rotating said wheel head to stabilize the workpiece, whereby the base portion of the turntable tool rotates with the workpiece, while the cap portion is substantially restrained from rotating; and applying a trimming tool to an edge of the workpiece to remove unwanted clay therefrom.

  • Publication number: 20080020084
    Abstract: A rotatable turntable tool, for use in trimming wheel-thrown pottery, includes a base portion, a bearing member, and a cap member which is rotatably attached to the base portion. The turntable tool is adapted to transfer downward finger pressure to the bottom of an inverted clay workpiece that is spinning on a wheel head of a potter's wheel. The turntable tool is provided to stabilize and hold the clay workpiece in place on the wheel head during a trimming operation, as excess clay is trimmed away from a foot area of the workpiece, and the shape of the foot is trimmed with a separate metal trimming tool. During use, the cap portion of the tool remains substantially stationary, while the base portion spins concurrently with the workpiece. A method of using the turntable tool is also described.
