Hi,
I made myself a turntable two years ago, starting with a 9“ thrust bearing used for rotating parts of furniture and heavy TV sets.
It works, but...
Made from Aluminum with steel ball bearings, the precision of the bearing is not comparable with thrust bearings for machines or vehicules. It also got a lot of friction and some spots where it turns rougher. The friction was reduced when I replaced half of the steel balls by slightly smaller Nylon balls. Still far from perfect, sometimes a cut is jarred when I turn over a rough spot.
The turntable can change height on a 2“ square aluminum profile, the black lever locks it there.
So, altough it works, I would not make it a second time like this, nor recommend this design to anybody. When I get round to built another one with real thrust bearings, this will be replaced.
