Sticking Steinway dampers

This statement could confuse some people.  The proper procedure (one
that works) is to regulate the timing of the dampers the the sustain
pedal so that there is a small amount of lost motion between when the
pedal is depressed and when the dampers begin to move.  Next set the
sustain lever stop block so that the dampers are raised the same height
as the sharp keys.  Next regulate the damper stop rail so the dampers
have but a tiny amount of lost motion after the pedal (not the key) is
depressed.

Finally you can regulate the sostonuto.  Set the blade so it is at about
45 degrees to the vertical, set the height of the blade tip to the same
height as the tip of the tabs.  With the action in and blocks in place
depress the sustain then the sostonuto, release the sustain and tap the
damper heads.  If any fall through the blade needs to be moved toward
the dampers.  Next depress the sostonuto several times to check if any
tabs are being touched.  If so tap the blade bracket toward the font of
the keys.

This should make all work well.
