Rubber Washer VPI Scout

No. The VPI tonearm has uni-pivot bearing which means it is self-leveled. Therefore, you need to level the platter to maintain the correct angle with the tonearm.

I would try it without the washer; I thought it made better contact with the platter that way anyway.

I thought the Scout came with a delrin, not rubber, washer. At least mine did when I bought it in 2010. Reading your question I'm not entirely sure what you're asking, but the purpose of the washer is to flatten the record as much as possible against the platter; it has nothing to do with leveling the table. You should level the table to insure the platter is perfectly level without worrying about the washer.

My experience with the washer has been opposite to Stanwal's -- the washer and the clamp make a tremendous positive difference when it comes to flattening records against the platter. I wouldn't play a record without it.

Actually, I never used the standard VPI clamp; I used either the TNT weight, the TTW weight or one of the TTW clamps. I still don't understand how having a washer under the record will give a tighter contact than having the record flat on the platter.

I myself use a Herbies Grungebuster Washer that he specifically makes for the VPI Spindle.

With Harry's design, the whole affair was designed to work together. The circular depression in the Platter, the Washer, and the cupped face of the underside of Clamp.

But one cannot just blindly clamp the bejesus out of a record, thinking if a little is good, then more is better.

Over-clamping will actually make the record's edge again lift away from the Platter.

The variance of clamping pressure then allows one to best couple the record on a record to record basis. That you have to observe the record's edge while clamping as it begins to make contact with the outer edge, and perimeter of the Platter.

Yes, there's perhaps going to be the occasional instance of where slight warps, or funny dishing-cupping of the record will not permit this design to work optimally.
Probably one reason Harry then came along with the Periphery Ring for later model Turntables.

With Clamps-Weights such as the TTWeights designs, I understand these are not to be used with the Spindle Washer.
