Does anybody know how or where to get a lazy susan bearing with an inner diameter large enough to fit the orbit balls in with some space to spare?
The KoP's lazy susan bearing is much too small, and I don't think cutting it would be a good idea because so much of it will have to be cut away. Online, the most I found was a 16" diameter lazy susan, which is kind of big, and the cross section is like a rectangle, so I doubt it would be good for our application of it.
What I was thinking was making a custom bearing, but I have no idea where to start in designing and fabricating one
. I thought about using some wood to make two platters with a circular channel for the ball bearings, but I don't know how to keep them together so the bearings don't fall out.
