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.


I checked Lee Valley. Load capacity 100 lbs. on the largest Lazy Susan.

They use roller bearings. Since I was going to suggest this was a roller
bearing application anyway it seems like a good fit... If these are high
quality they should be low friction. Maybe they would work...

Force is acting downward when stopped and mostly horizontal when rotating.



That was _1000 lbs._ capacity on the largest -- sorry! Please explain
why this would not work. Then maybe people will understand the problem
better.
