All the while the touch becoming lighter due to felt loss & geometry changes. It always Strikes me as such a sticky wicket. Don't you think? And then there's the scruffing scuffing hammer thing.</EM></STRONG></DIV> <DIV><STRONG><EM>  Dale</EM></STRONG></DIV> <DIV><STRONG><EM>  </EM></STRONG></DIV> <BLOCKQUOTE style="PADDING-LEFT: 5px; MARGIN-LEFT: 5px; BORDER-LEFT: blue 2px solid"><FONT style="BACKGROUND-COLOR: transparent" face=Arial color=#000000 size=2> <DIV>    I  grands, wont a let-off adjustment compensate for a slight filing. If hammers that have had medium to moderate wear are filed, why not adjust let-off? Why replace the hammers so soon?</DIV> <DIV> </DIV> <DIV>Julia</DIV> <DIV>Reading, PA  </DIV></FONT></BLOCKQUOTE></DIV> <DIV></DIV> <DIV> </DIV> <DIV> </DIV> <DIV><FONT lang=0 face="Book Antiqua" size=2 FAMILY="SERIF" PTSIZE="10"><I>Dale Erwin--Piano Restorations<BR>Modesto, Ca.<BR>Shop 209-577-8397<BR>cell 209-985-0990<BR></FONT><FONT lang=0 face="Book Antiqua" color=#000000 size=3 FAMILY="SERIF" PTSIZE="12"></FONT><FONT lang=0 face="Abadi MT Condensed" color=#000000 size=3 FAMILY="SANSSERIF" PTSIZE="12">Web site <A href="http://www.erwinspiano.com/">http://www.Erwinspiano.com</A> </FONT><FONT lang=0 face="Book Antiqua" color=#000000 size=2 FAMILY="SERIF" PTSIZE="10"><BR><B>Restoration & Sales of</B><BR><B>Steinway & Sons plus other fine pianos.<BR>Custom made soundboards by design<BR></B></I></FONT></DIV></FONT></BODY></HTML>
