string</FONT></DIV>
<DIV><FONT face="Arial Narrow" size=3>damper pedal

pedal</FONT></DIV>

rail: 1 mm of damper head when lifted
above position raised by black key with hard blow</FONT></DIV>

should move an amount equal to the distance which separates the center lines of
2 adjoining strings of a 3-string unison</FONT></DIV>

<DIV><FONT face="Arial Narrow" size=3>[How one measures 0.1, 0.2, or 0.3 mm of
lateral play in a key bushing, I don't know -- maybe with a dial micrometer
indicator. Same with the rep. lever height above the jack -- you just
learn it by feel, or by "winking" the jacks when the hammers are at rest.
And the spec for the una corda pedal (shift pedal) is awfully scientific -- no
consideration for voicing mentioned.] </FONT></DIV>
