It's all ball bearings. (sorta OT)
 

I've come into a number of ball bearings and I'm open to suggestions for projects in which to use them. They are "SKF 6304 2RSJEM Radial/Deep Groove Ball Bearing - Round Bore, 20 mm ID, 52 mm OD, 15 mm Width, Double Sealed, C3 Internal Clearance." I got them from a shuttered company that used to repair grinder pumps.

Maybe make some massive fidget spinners?...

How about some parallelogram linkages? The familiar parallel-ruler linkage using
four pivots can be tensioned with a bungee to make a fine featherboard,
or for a tablesaw's ripfeed holddown
or with a more robust screw tensioner, a variety of clamps (like bench holddowns or
vise-like holders).

How about a false-face for a vise jaw, that swivels?
One that swivels horizontally, another that does vertical.
Add a V-groove, the vise could clamp tapered legs.

The woodwork item known as a twin-screw vise https://youtu.be/TeprY3nwH9w
(for holding a board vertically) can be done with screws, or a wedge (across)
but also with a scissor-jack linkage. I like this with a router-friendly table
on top, for making sliding dovetail board ends.

The larger bearings, of course, could be used for a lathe spindle; old lathes were just a pair of
points hammered into a log, you can improve on that with a suitable heavy timber for
a lathe bed, and a motor surplussed from... a whatever. So, one of your points ROTATES.

How about a steady rest for your lathe...
