lost motion topic

Sometimes a few shims under the back rail will take up the lost motion,
then shim the balance rail to create key dip.  Much quicker than cranking
88 capstans and replacing 88 balance rail or front rail felts.  Be sure
you haven't lifted the front of the keys above the key slip, however, and
that the key rail or fallboard won't function with the changed key
height.

Actually you should look for a fundamental cause for the sloppy fit.  It
sounds like the keybed has found a new position??

Are the feet of the piano standing in water?
