Has anyone considered the centripetal force involved by the platter
spinning at 7K to 10K rpm? I vaguely recall somebody theorized that a
very massive spinning cylinder could cause gravitational effects.

A Swedish (?) experimenter reported that an extremely rapidly spinning
superconducting aluminium disk caused a gravitational anomaly. They
measured a decrease in gravitational force up to 3 floors above the
experiment site. I don't know if the experiment has been duplicated.
