I agree with Rod. I've PMed you on this too.

You can also back off the pivot nut too. It could well be that you've put the nut on a little too tight. If not then there is too much flex in either the ground board or the rocker box together, so the assembly flexes and instead of getting a nice even spread of the load over the Teflon pads, the load is being distributed to an edge, or even a point, of the pads.

Adding a "washer" around the pivot will help with this flex.

Let me know if you're stuck with getting your hands on some Teflon or laminate for this.

Also, where are the feet of the ground boards placed? They should ideally be directly underneath the Teflon pads. If not, this can make any flex issues worse.

One last thing, you didn't overtighten the screws holding the Teflon pads, did you? This can distort the pads, changing the shape of the contact surface. Even if the pads are loose on the ground board, rotating a little around the screw, it doesn't matter, they aren't going anywhere. As long at the screw heads are out of the way, no problem.

Oh, did you wax the laminate too?

It's all little details, I know, but it all helps if you go to this trouble to improve your scope.
