Vpi 3d Tonearm - Counterweight fitment


Question for anybody that owns a turntable with one of the 3d arms.

How well does the counterweight fit?

I have an issue... But not sure if it is an issue. The diameter of the hole on the counterweight is almost 2mm larger that the outside diameter of the back of the Tonearm. This means that the fitment of the counterweight is very loose since there is literally a 1mm gap all the way around. This makes setting tracking force and azimuth almost impossible.

The thumbscrew they included is useless, since you really have to crank it down through the insert just to make contact with the Tonearm.

Vpi sent me another counterweight but it is identical, same issue. Their solution was to send me a set screw with an Allen wrench so I can get more leverage to crank the screw down....

At this price point I'm having a hard time accepting this as a solution. Wondering if this is how these things are supposed to fit?

Thank you all, this is what I figured. I am going back to vpi with this info to get a replacement Tonearm. Since I have already tried 2 counterweights with them I would have to assume it's the Tonearm.
I have the same issue but not to the degree you're having. Seems I have to adjust the tracking force every two months or so, the tightening thumbscrew on the counterweight is 'self mis adjusting' on a periodic basis, didn't consider it might be the tonearm.. hmmm.
Had that exact problem with my Prime.   Finally admitted defeat and bought a different turntable. 
VPI ( the American company, we still want to support) would be better served as would their customers with hiring a QC guy.

After 40 years, why are we having this conversation? Frankly, if I owned the company and was driving a Maserratti, and could afford any audio component I desired, I would feel very guilty that my customers were having so many unavoidable problems.
