How do you install a 12" VPI armboard for 12" Unipivot on a VPI Classic 3 - Thanks :-)

Good point Lewm.

I would be extremely concerned about a "slightly wobbly spindle" and how it occurred to begin with?

Good point indeed.  The platter appeared to spin correctly, and there was no audible impact, despite the spindle's condition.  My guess is it happened the first time I re-greased the spindle.  When replacing the platter I hit the spindle a bit, rather than the platter going right on to the spindle.  The price of an education at least.  

PS Sorry I cannot post pictures of my VPI Classic 3 turntable with the upgrade to the 12" 3D tonearm as Audiogon does not allow photos.  C;est la vie!  :-(

The most important point is that you are very happy with your revitalized TT.
And it sounds like VPI stepped up as far as customer service is concerned which is great stuff.

As your name here says.... Have vinyl fun!

I am fortunately definitely having a lot of clearly. very improved vinyl fun!! 

I've also made two other VPI turntable improvements you may wish to consider for yourself :

1) Replaced the four VPI Classic feet with Isoacoustic GAIA 2's.
  GAIA"s come with three thread options, including the 1/4" 20 you need.
  In brief, their added vibration damping/control clearly gives my music      lots more clarity, detail and space...it was obvious...wow!

2) The original 10" tonearm lift could not reach up and lift the 12" 3D tonearm, even after using an Allen/hex key to make the max adjustment.  Adding a pad or similar on to the lift arm was needed.  The solution?  To be found at that well known, high-end audiophile store...Home Depot...I kid you not...cut to size some double sided tape, place on the lift, then cut to size and trim the height of a 2" circular black rubber washer to go on top and you're done.  More precisely "Scotch" brand "Mount" 15lbs strong tape and an "Everbilt" brand 2" flush valve shank washer...yes, the washer is originally meant for a toilet but it works great :-)
