This action height = is unique for each instrument, and is the result of the individual = string height for a piano. String height variables are the result of the plate fitting and belly operations... String heights change from = bass to treble usually in an arched or crowned manner. These numbers for note # = 62 represent an average. Maintaining the relationship between the stack = height and the string height ensures: A) the proper BLOW distance at the same time = the hammershank is properly off the cushion. and B) the proper HAMMER = ROTATION is needed to minimize overstriking or shallow striking conditon. NOTE; if = string height is lower or higher than above, keep the relationship the same..." = (and later after shimming or planing the bass and treble mounting blocks) "continually check for straightness with the straightedge on top of the hammershank flanges." I know you only asked for numbers, but what the = heck, I felt like sharing. BTW I'm sure you remember that we discovered when = shimming or planning it is best to rotate the stack on the hammer flange pin axis = which means adjusting the front foot differently than the back foot. Of course = there are even greater subtleties to this process but then you did just ask = for the numbers. Stay well, Chris Solliday  </FONT></DIV> <BLOCKQUOTE dir=ltr style="PADDING-RIGHT: 0px; PADDING-LEFT: 5px; MARGIN-LEFT: 5px; = BORDER-LEFT: #000000 2px solid; MARGIN-RIGHT: 0px"> <DIV style="FONT: 10pt arial">----- Original Message ----- </DIV> <DIV style="BACKGROUND: #e4e4e4; FONT: 10pt arial; font-color: = black"><B>From:</B> <A title=WOLFLEEL@UCMAIL.UC.EDU = href="mailto:WOLFLEEL@UCMAIL.UC.EDU">Wolfley, Eric (wolfleel)</A> </DIV> <DIV style="FONT: 10pt arial"><B>To:</B> <A title=caut@ptg.org href="mailto:'caut@ptg.org'">'caut@ptg.org'</A> </DIV> <DIV style="FONT: 10pt arial"><B>Sent:</B> Tuesday, July 19, 2005 = 9:53 AM</DIV> <DIV style="FONT: 10pt arial"><B>Subject:</B> [CAUT] Steinway stack height</DIV> <DIV><BR></DIV> <DIV class=Section1> <P class=MsoNormal><FONT face=Arial size=2><SPAN style="FONT-SIZE: 10pt; FONT-FAMILY: Arial">Hi = All,</SPAN></FONT></P> <P class=MsoNormal><FONT face=Arial size=2><SPAN style="FONT-SIZE: 10pt; FONT-FAMILY: Arial"></SPAN></FONT> </P> <P class=MsoNormal><FONT face=Arial size=2><SPAN style="FONT-SIZE: 10pt; FONT-FAMILY: Arial">I’m sure somebody out = there knows the specs for the distance from the keybed to hammerflange center and = keybed to wippen center for a Steinway B.
