I can't find anything to solve my problem because I obviously don't know how to
explain my problem.
I want the be able to spin by hand a heavy 24" round turntable on top of my
workbench using centrifugal force. Like the wheel on a car but horizontal.


Give us more info. What are you making? Will any forces be at work,
such as a cutting tool or shaping forces from the side? What weight
will be on the table? How much external force will be applied?


I was going to make it out of 4 inches of MDF but I can't find a bearing or
swivel or anything that will allow this top spin horizontally.
Lazy susans are strong and stable but don't allow a friction free spin.


Hmm, lazy susans don't don't much force to spin, even with 200# on
'em.

For a close-to-friction-free unit, mount a cut-off truck axle (with
bearing and wheel) to a metal frame and put an MDF (or real wood) top
on it.
