Re: Rotation Systems

We were quite pleased with our turret... it had 300+ degrees of rotation and about 45 degrees of tilt, and worked flawlessly all season.

If only the mechanism that loaded balls into it had done the same. Sigh.

In any case, we used an aluminum lazy susan bearing from Lee Valley Tools

The balls were loaded by a belt drive through the centre of the lazy susan.

Oh... yeah... we used a globe motor (with a 1" dia. pulley on it) to turn the turret using a 1/4" thick 15" dia. o-ring stretched around the outside of the lazy susan.
