Anybody heard Galibier or JC Verdier turntables?

"This is typically after every race and I do
know that the forces acting on the supension are greater than that of the pulley system acting on the side of the platter and it's spindle/shaft bearing."

You misunderstand what we are talking about when we say 'bearing' in the context of a TT. It isn't the spindle/sleeve surface we are talking about (this bearing surface has minimal load as you point out). We are talking about the thrust bearing load, and it is VERY substantial. 40 lbs on a point ain't nothing to sneeze at. It was already pointed out that the delrin thrust bearing went from a convex surface to a concave surface in one poster's experience. You can always change out the delrin bearing, however. I personally would be concerned with an increase in bearing rumble as the thrust surface wears...but that's just me.

I won't presume to speak for Thom, or Chris, but I can't help but think that what may be at work hear is the change in bearing surface contact area as the delrin thrust plate breaks in. That is to say, we first start with an extremely small point of contact that as break-in occurs grows to an optimum surface area where further wear is greatly reduced over time. Or, perhaps there is some material in this area of the thrust plate that is meant to give way during break-in.

I forget what it's called, but I remember there was such a material on crank shaft bearings that was meant to safely wear away during normal break-in of stock motors. We used to carefully polish that off when assembling race motors.

Thanks Dan,

Exactly my take on this. At some point, the forces equalize.

What really amazed me was how similar the rate of this dimple formation was - between materials so disparate as brass, stainless, and Delrin.

Limited computer access this week from Ottawa (nice town).

Cheers,
Thom @ Galibier

Dan_ed,
please explain the new direct drive comment:
"Chris, of Teres, is orgainizing an open house the night of the 13th and has told us he'll have a new direct drive offering as the top-o'-the-line Teres." Is it a Teres direct drive instead of belt drive?

Thom_mackris,
Is the Serac Turntable available for audition also?
