If I decide to continue down this path, I had planned to mount switches directly to the pizza pan, which would be triggered by L-Brackets which stuck upwards from the wooden mount which the whole unit would be attached to.
Thanks for the other kind words from all. I'm kinda at a "back to the drawing board" status with this until I find small casters..

Nice work..
I was worried the Cheap Lazy susan bearing would have too much play in them. I think if you employed a higher quality bearing this approach will work very nicely.
My Machine uses this exact same pizza plate.. If you are getting a lot of slippage (pizza plates are unfortunatley non-stick) , coating the plate with plasti-dip spray paint did wonders for the traction on mine..
(+_+):
You can probably get away with sandwiching a large plastic washer (those hard white ones) in between 2 - 5/8" pieces of mdf. One board would act as the stationary piece while the other one mounts to the LCD and swivels up against the washer. The entire sandwich is held together with a bolt and lock nut and tightened just right. You can even laminate or put a thin steel plate on the side that would be rubbing against the washer to prevent wear and tear.
Thinking about this a bit more, maybe even one of those heavy duty glisdomes instead of the washer since those things are as slippery as Mario Bros slip ice.

Great :applaud:
Nice try & great documentation :cheers:
Back to basics? A good big roller bearing should work nicely .. ;) Just saw off everything you don't need. I did.

I'm glad you posted this write-up. I'm in the planning stages of a rotating-monitor project and I was also planning to use a lazy susan bearing. Your comments about the low quality of the bearing worry me a bit. I can't help thinking it would be fine if the monitor were laying flat the way a lazy susan is designed to work, but mine will be tilted up about 50 degrees from the horizontal.
I'm planning to use a panel-mount LCD with a circular wooden frame (which will also support a rotating bezel), connected to a circular wooden backing, and then connected by the lazy susan to a supporting board. So it's quite a bit more elaborate.
I could incorporate another kind of bearing, a higher quality bearing, if I could find something appropriate.
The other thing is, it could be possible to put a board with pads of felt or teflon or somesuch underneath the pan (or the wooden backing, in mine) to support and stabilize it, do you think?
