Wurlitzer G411

[Tom Driscoll]

Dean,
Is this is a Chinese piano ?
    If so I have seen some warping keyframes with keydip changing from too shallow to excessive over a season --- especially here in the northeast.
One of the manufacturers  rep had me cut relief kerfs in both rails to "relax " the frame 
     then bed the frame as per your usual methods.
    If you check out the keyframes of different asian grand pianos you sometimes see these cuts on both the top and bottom of the front and balance rail members.
    I've done this on a few models with success on all but one . It continued to wang dang doodle with the next big humidity change and the piano was replaced through the dealer under warranty
    FWIW as this may or may not be the situation with your  Wurlie.

  A customer of mine has a Wurlitzer G411 in which there is approximately .090 inch of clearance in the middle between the front rail of the keyframe and the keybed.  The space decreases from the middle to each of the ends of the keyframe.

   

  What is the best way to solve this problem without sanding an enormous amount of wood from each end of the keyframe?
