Flexing of the shank happens in a vibrational pattern, and how many vibrations happen between push off and striking the string depends on velocity. The amplitude of flexing and the flexing "period" will vary with hammer mass and with shank grain/mass/stiffness/etc. <div><span class="Apple-tab-span" style="white-space:pre"> </span>I had always intuited that the hammer would be "flexed back" on a harder blow, so the front felt would contact. But I have come to the conclusion after watching Kawai and Birkett films and reading Askenfelt and others that it is not nearly so simple.<br><div apple-content-edited="true"> <span class="Apple-style-span" style="border-collapse: separate; color: rgb(0, 0, 0); font-family: Helvetica; font-size: 12px; font-style: normal; font-variant: normal; font-weight: normal; letter-spacing: normal; line-height: normal; orphans: 2; text-align: auto; text-indent: 0px; text-transform: none; white-space: normal; widows: 2; word-spacing: 0px; -webkit-border-horizontal-spacing: 0px; -webkit-border-vertical-spacing: 0px; -webkit-text-decorations-in-effect: none; -webkit-text-size-adjust: auto; -webkit-text-stroke-width: 0; "><div style="word-wrap: break-word; -webkit-nbsp-mode: space; -webkit-line-break: after-white-space; "><div>Regards,</div><div>Fred Sturm</div><div>University of New Mexico</div><div><a href="mailto:fssturm@unm.edu">fssturm@unm.edu</a></div><div><br class="webkit-block-placeholder"></div></div></span><br class="Apple-interchange-newline"> </div><br><div><div>On Jan 7, 2008, at 7:42 AM, Jim Busby wrote:</div><br class="Apple-interchange-newline"><blockquote type="cite"><span class="Apple-style-span" style="border-collapse: separate; color: rgb(0, 0, 0); font-family: Helvetica; font-size: 12px; font-style: normal; font-variant: normal; font-weight: normal; letter-spacing: normal; line-height: normal; orphans: 2; text-align: auto; text-indent: 0px; text-transform: none; white-space: normal; widows: 2; word-spacing: 0px; -webkit-border-horizontal-spacing: 0px; -webkit-border-vertical-spacing: 0px; -webkit-text-decorations-in-effect: none; -webkit-text-size-adjust: auto; -webkit-text-stroke-width: 0; "><div bgcolor="white" lang="EN-US" link="blue" vlink="blue"><o:smarttagtype namespaceuri="urn:schemas-microsoft-com:office:smarttags" name="PersonName"><div class="Section1"><div style="margin-top: 0in; margin-right: 0in; margin-left: 0in; margin-bottom: 0.0001pt; font-size: 12pt; font-family: 'Times New Roman'; "><font size="2" color="navy" face="Arial"><span style="font-size: 10pt; font-family: Arial; color: navy; ">David,<o:p></o:p></span></font></div><div style="margin-top: 0in; margin-right: 0in; margin-left: 0in; margin-bottom: 0.0001pt; font-size: 12pt; font-family: 'Times New Roman'; "><font size="2" color="navy" face="Arial"><span style="font-size: 10pt; font-family: Arial; color: navy; "><o:p> </o:p></span></font></div><div style="margin-top: 0in; margin-right: 0in; margin-left: 0in; margin-bottom: 0.0001pt; font-size: 12pt; font-family: 'Times New Roman'; "><font size="2" color="navy" face="Arial"><span style="font-size: 10pt; font-family: Arial; color: navy; ">That’s what I used to think too, but I guess high speed photography shows otherwise.

He used to refer to the front side of the hammer as the "carry side" and the backside of the hammer was the attack side. He believed that on a fast blow the hammer would overcenter the strike point on the hammer and hit string on the backside (attack side). Similarily, on very soft to medium blows it would be the front side (carry). If you want to produce more attack sound then, you place more hardener on the attack side of the hammer. He also said you only get one chance to apply lacquer. This is because the lacquer is a barrier unto itself. A subsequent application will not penetrate to a deeper level within the hammer.</span></font><o:p></o:p></div></div><div><div style="margin-top: 0in; margin-right: 0in; margin-left: 0in; margin-bottom: 0.0001pt; font-size: 12pt; font-family: 'Times New Roman'; "><font size="3" face="Times New Roman"><span style="font-size: 12pt; "> <o:p></o:p></span></font></div></div><div><div style="margin-top: 0in; margin-right: 0in; margin-left: 0in; margin-bottom: 0.0001pt; font-size: 12pt; font-family: 'Times New Roman'; "><font size="2" face="Arial"><span style="font-size: 10pt; font-family: Arial; ">Michael Wathen</span></font><o:p></o:p></div></div><blockquote style="border-top-style: none; border-right-style: none; border-bottom-style: none; border-width: initial; border-color: initial; border-left-style: solid; border-left-color: black; border-left-width: 1.5pt; padding-top: 0in; padding-right: 0in; padding-bottom: 0in; padding-left: 4pt; margin-left: 3.75pt; margin-top: 5pt; margin-right: 0in; margin-bottom: 5pt; "><div><div style="margin-top: 0in; margin-right: 0in; margin-left: 0in; margin-bottom: 0.0001pt; font-size: 12pt; font-family: 'Times New Roman'; "><font size="2" face="Arial"><span style="font-size: 10pt; font-family: Arial; ">----- Original Message -----</span></font><o:p></o:p></div></div><div><div style="background-image: initial; background-repeat: initial; background-attachment: initial; -webkit-background-clip: initial; -webkit-background-origin: initial; background-color: rgb(228, 228, 228); margin-top: 0in; margin-right: 0in; margin-left: 0in; margin-bottom: 0.0001pt; font-size: 12pt; font-family: 'Times New Roman'; "><b><font size="2" face="Arial"><span style="font-size: 10pt; font-family: Arial; font-weight: bold; ">From:</span></font></b><font size="2" face="Arial"><span style="font-size: 10pt; font-family: Arial; "><span class="Apple-converted-space"> </span><a href="mailto:itunepiano@aol.com" title="itunepiano@aol.com" style="color: blue; text-decoration: underline; ">itunepiano@aol.com</a></span></font><o:p></o:p></div></div><div><div style="margin-top: 0in; margin-right: 0in; margin-left: 0in; margin-bottom: 0.0001pt; font-size: 12pt; font-family: 'Times New Roman'; "><b><font size="2" face="Arial"><span style="font-size: 10pt; font-family: Arial; font-weight: bold; ">To:</span></font></b><font size="2" face="Arial"><span style="font-size: 10pt; font-family: Arial; "><span class="Apple-converted-space"> </span><a href="mailto:caut@ptg.org" title="caut@ptg.org" style="color: blue; text-decoration: underline; ">caut@ptg.org</a></span></font><o:p></o:p></div></div><div><div style="margin-top: 0in; margin-right: 0in; margin-left: 0in; margin-bottom: 0.0001pt; font-size: 12pt; font-family: 'Times New Roman'; "><b><font size="2" face="Arial"><span style="font-size: 10pt; font-family: Arial; font-weight: bold; ">Sent:</span></font></b><font size="2" face="Arial"><span style="font-size: 10pt; font-family: Arial; "><span class="Apple-converted-space"> </span>Friday, January 04, 2008 7:06 PM</span></font><o:p></o:p></div></div><div><div style="margin-top: 0in; margin-right: 0in; margin-left: 0in; margin-bottom: 0.0001pt; font-size: 12pt; font-family: 'Times New Roman'; "><b><font size="2" face="Arial"><span style="font-size: 10pt; font-family: Arial; font-weight: bold; ">Subject:</span></font></b><font size="2" face="Arial"><span style="font-size: 10pt; font-family: Arial; "><span class="Apple-converted-space"> </span>[CAUT] Voicing Steinway D</span></font><o:p></o:p></div></div><div><div style="margin-top: 0in; margin-right: 0in; margin-left: 0in; margin-bottom: 0.0001pt; font-size: 12pt; font-family: 'Times New Roman'; "><font size="3" face="Times New Roman"><span style="font-size: 12pt; "> <o:p></o:p></span></font></div></div><div style="margin-top: 0in; margin-right: 0in; margin-left: 0in; margin-bottom: 0.0001pt; font-size: 12pt; font-family: 'Times New Roman'; "><font size="3" face="Arial"><span style="font-size: 12pt; font-family: Arial; ">During a 3 day Concert Prep on a 10 year old D, I added Lacquer to power up the piano.
