[pianotech] Lowering the stack on a Steinway

[Ed Foote]

>> Looking for an efficient way to cut down the key frame rests for the 
stack feet and lowerthe stack by about 1/8"+.  Any suggestions?

Greetings,
    A small backsaw with a stop clamped along the blade 1/8" from the 
edge of the tooth will let you make depth guide cuts, (just like when 
setting bearing). Then just use that sharp chisel. The treble end 
doesn't allow this, so if you need a guide there, use a small Forstner 
bit. (now that I think about, a Forstner in a drill press might be the 
best way to lower all the cleats!).
