As with the others who tried it: I found the lazy Susan bearing to have not enough friction by itself. I was dissatisfied with the sticktion of the stock base of an XT-6i I used to have, so I installed a lazy Susan bearing. That completely cured my sticktion problem, but the scope wouldn't stay put when I got my target centered.
I installed a screw through the base of the rocker box. The screw had a nut with a fender washer welded to it and I stuck some felt to the fender washer. I hope that makes sense... I could then advanced the screw such that it pushed the felt pad against the ground board. With a little fiddling I could get just the right amount of friction without introducing any stiction. It worked very well and was quite smooth to operate. A very good upgrade in my opinion. Just more complicated than I thought when I started.
Only after I'd done that work did I talk with a couple of friends of mine who use Dobsonians all the time. I was told the more usual cure for sticktion is to fiddle with the diameter for the PTFE pads Dobs usually "ride" on. Smaller diameter pads means less stiction. Now I know.
