Hi tammy, this is on andrews site:
The leaflet included in discontinued GSO Dobsonian style telescope base boxes showing needle roller bearings and steel sheets being incorporated within a rotating base is incorrect. In fact, teflon pads are fitted to those Dobsonian telescopes' bases!
The new Adjustable tension Super Deluxe (ASDX) GSO Dobsonians have an upgraded needle roller bearing rotating base which now incorporates thicker steel plates.
