I was browsing around the web and see that there is a growing trend of people using LP records in az bearings in place of the trusted ebony star. Anyone here used an album for this purpose, and how well does it work?

I built a 6" f/9 dobsonian solar scope under the direction of John Dobson and we used a 33rpm vinyl record as a bearing surface with teflon. The motion is smooth and even. The only problem that I have experienced is that when I rotate my telescope counter clockwise it plays demonic messages!

Hi Evan, I used this method on my first scope and it worked very well. A second thing that you can do which helps make the motion smoother is to cut plastic washers from gallon milk jugs, and use them on the Az axis. It helps firm up the load and keeps the base from rocking when you spin it.
Good luck Dave

Did this on my dob starting out. Thought it was pretty good until I broke down and got teflon and Ebony Star. No comparison after that. MUCH smoother. The lp gets gummed up after awhile. Did on mine. It will work until you break down and send away for some Ebony Star. 
I believe some Magic Sliders do have some teflon so that may not be as big a difference. I got Ebony Star here after placing a wanted ad. Quick, easy, good price.
