  ToSubject: upright side panel



  Hello list:

  Since I've spent most of my time learning tuning and regulation and =
all the things that go with that, I havent spent much time studying the =
actual physical case construction of an upright piano, so here goes a =
possible stupid question:
  The upright I recently saw had the right side almost completely =
delaminated from the piano.  I mean from the pin block to the back, and =
almost all the way down to the floor.
  1.  Does this structurally impact the sound board?
  2. Can this be easily fixed by re-gluing and clamping
  3.  Is there other ramifications to re-gluing that I just dont see or =
understand?

  I sure appreciate your comments
  Thanks
  Dave

      Dave,
      The soundboard -back assembly is independant from the side panel.
      Glue and clamp  with basic woodworking techniques.
      On a beater with no cosmetic issues in play ,I have added screws =
through the side panel into the back assembly.
      The Winter spinets of the 40's -50's have this tendency.
      One clue will be lots of lost motion on one side of the action or =
the opposite with hammers off the rest rail . Also dampers not lifting =
correctly with the timing all over the place.
      Reason being the keybed attached to the side changing in relation =
to the strings-back.
  With the side -keybed correct, the action should be back within =
reasonable regulation (If it was before !)
      Good luck,

      P.S. ,
      The archives have this question answered if I remember.
