ianlane,
You don't indicate if you purchased the TW new or used. Either way, if the fit of your platter to bearing is very loose it could be the result of having been played dry with insufficient lube for long periods of time. While the new heavier lube now being used by TW could be of some help because of its heavier viscosity I would advise you to contact Jeff Catalano at High Water Sound and discuss it with him.
