IDEA NOTE Locking the turntable
The bolt to lock the turntable into position is one in the center. To prevent loss of the center bolt, the bolt is designed not to be removed from the turntable.
IDEA NOTE Preventing deflection of the turntable
To prevent turntable deflection urethane mold bearings are placed on the table bottom surface at three locations.
