VPI 2nd Pivot for 3D

Dear Raul,
It's ok.... I knew you were talking about a vintage item. I'm guilty of  conversationalising off-topic. :(
Apologies Stringreen.
best regards,
Bill

I tried to follow this thread and went cross eyed.  Maybe it is my limited intellect.  All I know is that Springreen's original post is correct.  What follows includes a lot of opinion based on limited or no experience with the product under discussion.  I also cannot understand the broken English of Raul, which is unfortunate.  Perhaps someone can offer a synopsis of his main arguments that would help to elucidate me?

I own one VPI metal arm with dual pivot, one VPI 3D arm with dual pivot, one SME Series III arm, and one SL1200GAE with gimbal arm.  Properly set up they all sound quite good when mated to compatible cartridges and amplified with high quality electronics. 

..just a suggestion for those setting up the 2nd pivot. Attach the gizmo to the arm, but don’t let the 2nd pivot touch....just unscrew the adjustment until it doesn’t make contact. Use the Fozgometer, and then adjust the meter by very slowly screwing down the adjustment screw. When you get the ideal - only a bit off.... use very little adjustment to perfect the result.

...and another discovery with the 2nd pivot.  This may or may not be true...true in MY system.  When releasing the cuing device, if the Azimuth is spot on, the arm will be lowered straight onto the leadin groove.  If off, even a bit......the arm veers off course.
