U.S. Art Supply – 11″ Round Plastic Pottery Wheel Bats, Set of 2 – Durable, Balanced Bat for Use Spinning Clay & Making Ceramics – Design To Only Fit U.S. Art Supply Pottery Wheel Set of 2 – 11 diameter round plastic pottery wheel bats. Bats are made for use with the U.S. Art Supply Pottery Wheel (Model # USA PW-101). Bats are 3/8 thick and made from durable injection molded plastic that resists warping and stays centered balanced when in use. They contain three pin mounts on the underside to lock it into place on the wheel head. The bat can be easily lifted of the wheel head because of the lip that extends slightly past the wheel head when it is mounted on it. While the bat is in use there is still enough clearance for you to have full access to the splash pan surrounding the wheel head. Ideal for use when spinning clay to make all types of ceramics like pots, bowls, cups and artwork.
