Abstract
A system may be used with a pottery wheel to facilitate the shaping of a workpiece. The system may have a support assembly coupled to a rotatable wheel of the pottery wheel, and a template holder that holds a template relative to the wheel. The support assembly may have a rotary coupling to which the template holder is coupled; thus, the template holder may be used to keep the template stationary as the wheel, workpiece, and support assembly rotate. The template may be used for jiggering and/or jollying, and may have a plate with a shaping surface that contacts the workpiece during relative rotation to provide the desired contour. The template may have a plate that is insertable into a slot of the template; the template may be retained by the template holder at multiple displacements from the rotatable wheel.
