Steinway regulation

Pianos differ in many ways.  Start with a dip of .395" (10mm) and blow
distance of 1 3/4" (48mm).  Regulate two or three keys completely to
see how they feel.  There should be about .40" of key movement after
the jack leaves contact with the knuckle.  You can check this by
placing that much extra on key pin and check to see if you have extra
movement or not enough for escapement.  If needful move the hammer
slightly closer to the string.  If next needful remove .010" punchings
from under the key.  If all is right, geometry, hammer bore, capstan
placement, you should have a nice touch to work toward.
