And another good reason for the development of synthetic wool for piano use (besides the serious effect of humidity on hammer tone with sheep's wool) is "touch". Sheep's wool probably expands when humid, affecting touch via increased friction on contact points ( and encouraged swelling of adjacent wooden parts) and also via increased hammer weight.<br> <br> Thumpe</div> </td></tr></tbody></table> <div id="_origMsg_"> <div style="font-family:arial, helvetica, sans-serif:font-size:10pt"> <br> <div style="font-family:times new roman, new york, times, serif;font-size:12pt"> <font size="2" face="Tahoma"> <hr size="1"> <b> <span style="font-weight:bold;">From:</span> </b> Delwin D Fandrich <<a href="mailto:del@fandrichpiano.com">del@fandrichpiano.com</a>>; <br> <b> <span style="font-weight:bold:">To:</span> </b> <<a href="mailto:pianotech@ptg.org">pianotech@ptg.org</a>>; <br> <b> <span style="font-weight:bold:">Subject:</span> </b> Re: [pianotech] Brighter Yamaha <br> <b> <span style="font-weight:bold;">Sent:</span> </b> Fri, Nov 30, 2012 5:55:38 AM <br> </font> <br> <table cellspacing="0" cellpadding="0" border="0"> <tbody> <tr> <td valign="top" style="font:inherit;">Wool is hygroscopic. It does absorb and desorb moisture and the tone<br> characteristic changes as a result. Normally the change is slight and<br> gradual. This may not be so slight. <br> <br> I'd certainly let time do what it will before attempting to chemically<br> harden hammers that already have the reputation of being granite in<br> disguise. And then, if they do not harden up enough to cause permanent<br> hearing damage after they have dried out I'd sand off a layer before pouring<br> on the chemicals.

As a follow, I've that high humidity has an<br> effect on hammers. This piano sat in empty house for five years in Hilo, but<br> was moved to Oahu 2 weeks ago and is now in an air condition hall. <br> <br> Hilo is on the Windward side of the Big Island of Hawaii, where it rains A<br> LOT. The piano is only 6 years old and has never been used. It has had a<br> string cover and a damp chaser, so there no damage, and the hammers are<br> virtually brand new. <br> <br> Would the being exposed to a lot of humidity be the reason the hammers are<br> soft, and if I just wait 6 months they will brighten up by themselves?<br> <br> Wim<br> Sent from my iPhone<br> <br> On Nov 29, 2012, at 3:57 PM, <a>tnrwim@aol.com</a> wrote:<br> <br> > We usually have knock the edge off Yamaha hammers.
