Warped Ivory Keys

[Farrell]

There must be some observable separations in the wood? Yes? If so, glue and clamp may be just what the doctor ordered. First test with clamp to see if it will compress flat. Sounds pretty weird.

  Subject: Warped Ivory Keys


  A 1902 Mason & Hamlin upright I worked on has ivory keys that are
  warped upwards where the head and tail meet. They are not coming
  unglued, both the wood and the ivory are warped upwards. This affects
  about half the white keys, and is severe enough to be a major
  distraction for the player. 
  Does anyone have suggestions on how to remedy this - perhaps without
  removing the ivory? I could only think of steaming and clamping, but
  haven't tried anything yet. Thanks.
