Project Elemental vibration

[gregs656]

I've had my Elemental set up for about 18 months. I use it fairly regularly, most weeks but not every day and it's always been in the same spot. Earlier this month it was vibrating like mad. I bought a granite chopping board and it has helped a little but it still skips frequently - basically unusable.

Suggestions? My apartment backs on to an elevator shaft and they have changed the cables on the elevators recently which I guess could be causing a different vibration?

I also wonder if it is a motor problem? If I take the belt off there is enough play in the motor spindle for it to audibly rattle which is sending vibration through the body, but I assume the tension of the belt against the deck would be enough to mitigate that?

It's really annoying as I haven't changed anything.

The granite chopping board is on the foam feet it came on, and the elemental is sitting on its foam feet on that.

Two possibilities: significant structural vibration in the building making their way to the precise spot your turntable happens to be placed, or the motor bearings have gone. Which one reads as more plausible?
