[pianotech] Bridge pin locations help (image oops)

[Gene Nelson]

Keith,
Here is one option to consider.
I did an in home repair once that worked for a bridge/unison that was in 
need of more help than yours.
Just removed the strings, then removed the bridge pins on the speaking side 
of the offending note. Then centered a forsner bit over the bridge pin holes 
and notch, then drilled into the bridge root. Filled the hole with a 
Dilignit plug - epoxied it in. Then trimmed the plug flat to the bridge cap 
with a chisel, drilled new bridge pin holes and carved a new notch, inserted 
new bridge pins . Acton Dag hid the bulk of the repair. Worked just fine and 
not very difficult.
I believe that I learned it from Nick Gravagne.

List,

I decided I would share a situation I have had
  to live with for several years.

I regularly tune a 2001 Steinway Concert Grand that has
  a definite issue with the location of the bridge pins.
    (see image)

Throughout this piano there are varying degrees of
   misplacement of the bridge pins, however the one I focused on
  is by far the worst offender and produces false beats beyond belief,
  hence I added the PitchLock String Coupler to reduce the false beats 
existent.
         (  http://www.pitchlock.com  )

Does anyone have a surefire method to correct this issue
  without a tear down?    (larger pic available if needed)

Sincerely,

Keith McGavern, RPT
