Apertura azimuth motion and stability fix

	Mount	Ring O.D.	Price
	AD6	16.0"	$32
	AD8	18.5"	$38

	AD12	23.3"	$50
"Lazy-Susan" style azimuth motion lacks "stiction", lacking smooth start and stop motion. Laminate and Teflon provide smooth control and buttery motion. Rocker boxes riding on an OEM ball bearing tray halfway to the pivot bolt (instead of the perimeter) induces lack of control azimuth motion and wobble. Adhere laminate ring with contact cement. Screw Teflon pads onto ground board over the feet: Easy fix! Includes: Laminate ring, predrilled Teflon pads, stainless steel Philips screws.
