The contraption used for pot throwing, so named because of its use of wheels. It consists of a flat disc from a quarter- to a half-meter in diameter on top, connected to a flywheel by a vertical shaft. Both wheels are horizontal. A person sits level with the disc and kicks the flywheel to set the whole apparatus spinning. This spinning provides the centrifugal force required to stablize the clay (which is placed on the disc) while it is being shaped.
