  • Patent number: 5137065
    Abstract: A lathe tool includes a stiff shank and handle portion and, adjustably extending forward from the shank, cantilever fashion, an elongated resilient blade. The combination is configured and disposed on a tool rest so that, when the tip of the blade engages a downwardly moving surface of a workpiece, a vibration or chatter of the blade results and produces a three dimensional textured pattern on the workpiece. Pattern and texture may be selectively varied by adjusting the unsupported length of the blade (to control its frequency of vibration), by changing speed of rotation of the workpiece, by changing pressure of the tool blade on the workpiece, and by lateral and rotational manipulation of the tool.
