@nsp,

You keep writing "the belt is rubbing on my platter". This very statement is wrong. Your belt is rubbing on the metal plinth. 

It's important to get our/this portion correct. Going forward, you need to be able to distinguish between your platter and your plinth.

@nsp ,

You do know the belt NEVER touches the platter...it goes around the sub-platter/motor pulley.

@nsp, the Triplanar, another mighty fine arm! Another good arm for the Rock is any of the Kuzmas. It has been said that the Rock minimizes differences between arms, but differences nonetheless remain. An arm partnered a lot with the old Rock Elite (Mk.2) was the Zeta, the combination I own. Right after the Rock Mk.7 was introduced, I ran into Max at CES in Vegas, and asked him how much better than the Mk.2 was the Mk.7, and he said "just", positioning his thumb and pointed finger with but a tiny gap between them. I intend to eventually own a Mk.7, but until then, my Elite will suffice ;-) .

 yes I understand the belt goes around the sub platter/ motor pulley. What I referred to as the platter maybe what you call the plinth. The plinth  is what the record is placed on top of. As Max says in his diagram the belt should never touch a platter or the chassis. in in my situation the top of the belt scrapes ever so slightly against the bottom of the plinth/ platter. I eyeballed and try to I I bald and try to measure the top of the motor housing to the top of the chassis. My motor housing top is significantly higher than the top of the chassis. It's not a half inch but maybe a quarter of an inch. I think this is the problem.On your setup are the top of the motor housing  and the top of the chassis the same height?

slawAlso Max indicates in writing and his diagram that the belt should run over the transition between the top cylindrical section of the motor pulley and the center tapered section. my belt does not do this it runs almost all the way towards the bottom the motor pulley.
