Somebody broke the original key slip. Obviously the keyslip has to be higher than the thickness of the keyframe + punchings + dip. using the available punchings when the piano was made. Glue a strip of veneer to the bottom of the keyslip Keith R ----- Original Message ----- From: "Breakall, Raymond" <rbreakal@richmond.edu> To: <pianotech@ptg.org> Sent: Friday, July 19, 2002 10:10 AM Subject: RE: Bechstein key height > Tom, > > It's simpler than that - If I have the keys in I have to have a certain > thickness of back rail cloth so thet the keys fit with the keyslip.
