Are you sure you have the second pivot mounted correctly? There are no movement issues with mine. My only negative is that like some others have reported, the adjusting set screw is a little loose and can move on its own unless you add a little Teflon tape to the threads -- which is a little tough to do given the size. For $150 I wouldn't expect that to be the case, but I have a suspicion as to the underlying cause. The screw that attaches the second pivot to the arm takes a standard hex key. The adjustment screw on my unit, however, requires a metric key. My theory is that the adjuster threads are cut for SAE, but some units were shipped with metric set screws by mistake. Eyeballing it, the set screw is about 1/8" in diameter. An M3 screw is about .007" narrower which would account for the slight play. Of course I could be wrong and it's just sloppy machining on either the set screw or the second pivot body. Regardless, it was a worthwhile mod for me.

If your counter intuitive is hitting the slide plate, you placed the plate too far back. Also, get the 2nd pivot right up to, but not touching the inside azimuth weight. I actually load the pivot a tad heavy and then use the outside azimuth weight to balance out a bit of it. Infact, I turn this weight out until the pivot comes up, and then turn it in one full revolution to load the pivot.

JimTimP that is exactly how I do it and it always works.

You need to set the arm height so the azimuth ring is at least 3/16" above the arm base, you mount the second pivot next to the left side weight, set the height so the cartridge tracks level, put a drop of white glue on the threads and it will never move till you want it to.

If there is something wrong with your unit send it back and VPI will send you a new one but I have yet to see one that was not right and I have installed over 20 of them.

Hey JimTimP - some pictures would be really appreciated if you have time of course, as visuals are a lot easier for me! ;)

I find it a pain in the whatever. Yes indeed it improves the 3D, but also constantly changes adjustment. I tried Loctite purple, wasn't easy to apply, got it all over but cleaned it up. The tonearm had to be raised....that put the cueing device out of adjustment. Then I found that there wasn't enough pressure for the second pivot..the arm rattled against the plate... so had to twist the rear counterweight to add pressure for that adjustment...which of coarse knocked out the vtf, which I had to adjust again. We'll see what my Fozgometer says tomorrow when the loctite dries.
