This Bat System is made specifically for the Shimpo Aspire pottery wheel. It contains one master bat and 7 mini inserts. This bat system will NOT fit traditional full sized pottery wheels.
Inserts are 4.25″ in diameter. Master is 10″ in diameter.
Due to manufacturing tolerances on wheel heads and bat pin placement your master bat may fit very tightly on the Aspire wheeled, Lightly reel or sand bat pin openings if you need to make adjustments for fit.
