Bechstein key height

[Breakall, Raymond]

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. If I
make that right (so that you can't see the bottom of the key), Then even
with the thinnest front rail punchings, I barely get 10mm (3/8 in)of key
dip. I don't have room to add paper punchings to make the dip even.

John,

Thanks for the reply but the problem is that the keys are too high
already
in relation to the key slip. I have the thinnest balance rail punchings
sold
by Schaff and their are no glides on the keyframe. Sounds like the other
thing to do is have the keys too high in relation to the keyslip. Any
other
ideas?

Ray, 
	Start fresh. Sample combinations of backrail cloth, balance rail
punchings, and frontrail punchings. Fit the keys to the fallboard,
keyslip and height of front rail pins,and check the relationship to the
damper levers. 
      At one time the key height -dip relationships worked in this piano
and I'll bet that someone has messed this up with some incorrect
thickness's. Treat this from scratch and the piano will tell you the
correct choices.   Tom Driscoll
