Basically my thoughts exactly. Please let us know the final outcome when resolved. Best Joe
This is the same possibility Jack Shurtz brought up when I called him. I will dissemble, shim ever so slightly and install new felt and reassemble. He suggested some flex in the slate on that edge.
About the nicest I've ever seen.
I'm kind of fuzzy looking at that entertainment center, but might it be that the slate just wasn't machined as true as it could be? or maybe the frame is not supporting it properly? I do know that slate will flex some, even one inch thick. If you are getting roll off from the balls, but it is not consistent throughout, then I would think that would be a good indication that the slate is convex, or concave? If it's high in the middle then I think RKC has a cure for that. If memory serves me correct he was able to do that with a Gold Crown that he worked his magic on.
