Let's fix this! Roller ball bearings are too fast and do not provide any "stiction" for proper smooth startup and stopping motion. Having the mount's rocker box riding 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 and 1/4" thick Teflon pads and positioning are the right combination.
