The physics of a slightly off-center ring flywheel are complex. Even with the inner & outer ring perimeters shifting slightly, the majority of the ring's mass remains concentric. The net flywheel effect may still be superior relative to no flywheel at all. However, like an unbalanced auto wheel, there may be odd resonances at particular speeds of rotation-- but probably not a problem with a flywheel running a slow 33.3RPM.
Periphery Record Rings
Who uses one of these periphery record rings, like the VPI? Theoretically they make a lot of sense. What is your experience with them?
Has anyone seen this auction over at Audiogon ...

It's a brass ring without the outer downward facing "lip" on the VPI ring, which won't work on all tables due to lack of belt clearance. I would guess brass would be better, since it is denser and purportedly results in better sound than other metals. Anyone seen one of these "ttouter" rings and can vouch for the quality of the workmanship and uniformity of it?
thanks,
Bob
