Let's fix this!
Also avialable combined into our Integrated EZ manual setting circles.

Ball bearing "Lazy-Susan" style roller azimuth motion is just way too fast, lacking any "stiction" for smooth start and stop motion. Our combination of the proper laminate riding on Teflon gives smooth control with buttery motion.

Supporting the rocker box on a small disc halfway to the pivot bolt, instead of at the perimeter transfering weight though the feet to the ground, invites speed and wobble.

Laminate ring with Teflon pads positioned outside over the feet: Easy fix!
