I have a Sota that I am rebuilding, and got a new motor, controller and sub chassis spring kit.
Plus a new arm and arm board, and cart.
So I now have an old motor, and wall wort.
An old arm, and an old cart.
If I can find a bearing assembly that would be great. A magnetic levitation one would be even better.
Where does one find a source for this stuff?
(The ClearAudio importer said that they will not sell an upgrade MagLev spindle without a trade in of the old part.)
Basiically I want a TT for the shed or give to one of the kiddies.
I have access to a lathe to make a platter, so I can make it fit whatever bearing I might stumble upon..

Metal lathes were more or less made for making bearings. (OK, and screws; but screws became commodity and bearings seem to be a lot custom.) Bore a hunk of brass, turn a steel rod, make them fit sweet. Lap by hand with toothpaste for final fit. (Your grandfather used dye and a scraper to fit engine bearings.)
Just a silly thought: Have anyone tried VHS video drums for this purpose?
Made a turntable some years ago. The platter was quite lightweight. Worked pretty well.

What was the nature that made it a failed folly?
If nothing else the thing would seem to be a bit more tolerant of vertical vibrations?
Assuming I wanted a tried and true design then wherewould I purchase those from?
That 'mag-lev' turntable supposedly went through extensive laboratory research before it was introduced - and multiple reviews, along with some videos that I happened to see clearly showed the nonsense behind its design.
It was obviously designed to 'impress' in a visual way.
However its design created flaws, a wobbling of the platter, and a dangerous high magnetic field that interfered with people's heart pacemakers, among other things.
It was one of those rediculous inventions born from that shady 'kickstarter' website, which also is known for its shady money donation handling practices.
Besides, the best way to design a turntable system is to have the platter and tonearm mounting 'locked' strongly together rigidly on the same platform to eliminate any issues.
Lovely place.
I remember being there maybe ~2008.
Young lady near the museum had a blue and yellow shirt that said “Kiss me I am Ukrainian”.
I asked her if I could take her picture and she said why?
I said my coworker is Ukrainian.
She said what’s his name.
I said “”Igor za… Za <and made some throat sounds.>”
She said, “You are telling the truth, you may take the photo.”
Is the bearing usable/inner platter usable? And worth starting from?
Certainly a good basis for a diy TT. It is the bearing assembly left fter a friend upgraded his Linn (likely not the only time). Adapt the support plate to your plinth, add a belt, motor and arm. Hargest part is the platter. Simpliest might be a solid surface material. CNC would be nice, but careful and skilled use of a router work. That is what i have on my Rega.

I have the belt motor and arm.
I am trying to figure out how to send a PM (maybe I need more posts?)
a picture and/or height might help.
But it sounds pretty doable, and I have a router.
