It is not uncommon to find instruments where a technician has 'bedded the strings' so effectively that they are embedded in the bridge cap. This will cause the string termination to be bourne by the bridge notching in front of the pin.</div> <div><br></div> <blockquote type="cite" cite><font face="Arial" size="-1">Hammers are quite light (4.3 g for the highest trebble, 6.0 g for note n°60), and new shanks are already tapered in the last section.</font></blockquote> <div><br></div> <div>Hammers are unlikely to be the problem with regard to sustain. But the sound board might well have deteriorated. Check it for curve with a thread underneath. Many of the 1920's instruments I've inspected are due for a new board.</div> <div><br></div> <div>Ron O.</div> <x-sigsep><pre>-- </pre></x-sigsep> <div><font face="Times New Roman" size="+1" color="#0000FF"><b>OVERS PIANOS - SYDNEY</b></font></div> <div><font color="#000000"><i>   </i></font><font color="#0000FF"><i>Grand Piano Manufacturers</i></font><font color="#000000"><br> _______________________</font></div> <div><font size="-2" color="#000000"><br> </font><font color="#000000">Web http://overspianos.com.au</font></div> <div><font color="#000000">mailto:info@overspianos.com.au</font></div> <div><font color="#000000">_______________________</font></div> </body> </html>
