Let's fix this!
Consider combining with Integrated EZ manual setting circles.

Roller ball bearings are too fast lacking any "stiction" for smooth start and stop motion. When the rocker box rides on a small diameter footprint instead of at the perimeter of the ground board is an invitation to wobble. Finally, the mount's weight should transfer directly into the ground board feet, not halfway to the azimuth bolt - in order to eliminate flexure and possible vibration.

Our laminate rings, 1/4" thick Teflon pads and positioning over the feet are the right stuff!.
