BlairR,

I may be missing a few appends to your posting, but I still do not have a
picture of what you are trying to do.

You want to spin by hand, not turn, a 24" diameter, 4" thick MDF turntable
located on your workbench. And you want it to spin this turntable with
something unknown on it, at some unknown rpm for some unknown period
of time.

Although I've seen a number of solutions offered, I submit to you that if
you
describe in some detail what you are trying to accomplish with your
turntable,
you will give the talented folks in this group a clearer picture of your
problem
and they will come up with workable ideas and maybe even the answer to
your 'prayers.'

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.

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.

I'm sure what I need is out there but I have no idea what it is, or what
it's
called.

There are all sorts of bearing to spin stuff vertically, isn't there one I
can
attach to this table that doesn't cost hundreds of dollars.
