IOW, might they be hitting the strings square (remember the the plate and thus string plane are already leaning forward to move the center of gravity frontwards), and what you're looking at is an extreme rake in the boring. If that's so, the rake come from moving the bore point back n the hammer molding. Doing this moves the butt's c'o'g back from directly in top of the butt center, helping it's return to the rest rail. </DIV><DIV><BR><BLOCKQUOTE type="cite"><SPAN class="Apple-style-span" style="border-collapse: separate; -khtml-border-horizontal-spacing: 0px; -khtml-border-vertical-spacing: 0px; color: rgb(0, 0, 0); font-family: Helvetica; font-style: normal; font-variant: normal; font-weight: normal; letter-spacing: normal; line-height: normal; -khtml-text-decorations-in-effect: none; text-indent: 0px; -apple-text-size-adjust: auto; text-transform: none; orphans: 2; white-space: normal; widows: 2; word-spacing: 0px; "><FONT face="Arial"><SPAN class="Apple-style-span" style="font-family: Arial; ">Does insalling new hammers so that they strike the strings at 90 degrees improve things? </SPAN></FONT></SPAN></BLOCKQUOTE><BR></DIV><DIV>You've got a perfect chance to check this out with the old hammers.
