Somewhere I have a diagram of a gadget that pulls the strings out of the
way so you can work on the bearing surface.
If you want, I'll look for it and send you a copy.

I am told that the main problem lies in the V bar, not in the hammer,
and that smoothing the bar with sandpaper will clean up the termination
and permanently fix the buzz.  This is one of the few things I did not
do, since I was really originally only out for a warranty tuning  ;  )
Thoughts?

I have always struggled with the capo buzz in many pianos. Young
Chang/Prambergers I've never succeeded with, Steinways, I usually can do
it.   I have discussed this many times with many techs.  I am exhausted
after a 14 hour day with three B's one of which is still giving me fits.
It is a new Steinway B, prepped by a large reputable dealer.  The piano
was/is nice.  But it was a little bright after some play and I went in,
pitch raised it, stopped sympathetic aliquot ringing, leveled strings
with my Mother Goose leveling tool, fit hammers to strings, worked on
damper bleeding, etc.  There were several hammers, especially the first
C at the V bar that had a buzzing quality.  I sugar coated/voiced, 3/8"
needled the shoulders, evened everything out, got it acceptable, and the
buzzing returned, a bit.  Enough to bug the customer.  
 
After more sugar coating (shallow needling at crown) and more 3/8" inch
needles just off of the string marks (both straight down and in at an
angle), I am at the point where I am killing the bell quality and volume
to extinguish the metallic buzzes.  I believe these hammers were
hardened with lacquer, not key top solution.  Tapping strings onto
bridges, done, seating strings at every termination point, done.  This
exists to some extent throughout the V bar area.  This is the buzzing
that goes away when you put your finger on the front duplex section.
Just hoping I may hear something new (hoping not to hear a buzz).  I
appreciate any new suggestions, I am so worn out!
