ABSTRACT:
A wheelhead assembly for use upon a vertical rotary power drive shaft of a potter's wheel includes a top plate, a drive shaft coupler, and a locking arrangement for releasably securing and adjustably relocating the top plate relative to the drive shaft coupler. The top plate has a planar upper surface for supporting a mass of clay to be molded into a composite article of pottery. The drive shaft coupler has a fixed axis of rotation and is capable of supporting the top plate upon the rotary drive shaft of the potter's wheel for rotation with the coupler about its axis of rotation. The locking arrangement is disposed along the underside of the top plate and is capable of releasably securing the top plate to the drive shaft coupler and of adjustably relocating the top plate relative to the ddrive shaft coupler to a selected one of a multitude of different position along orthogonal X-Y coordinates defined by the locking arrangement to thereby relocate the axis of rotation of the drive shaft coupler relative to the top plate to the selected position along the orthogonal X-Y coordinates.
