that one was now no longer being compressed, so I moved it closer.  The first one started to make noise again.  After moving it a lesser distance closer, they both were quiet enough.<o:p></o:p></span></font></p> </div> <div> <p class=MsoNormal><font size=2 face="MS Sans Serif"><span style='font-size: 10.0pt;font-family:"MS Sans Serif"'> <o:p></o:p></span></font></p> </div> <div> <p class=MsoNormal><font size=2 face="MS Sans Serif"><span style='font-size: 10.0pt;font-family:"MS Sans Serif"'>I cannot say that I have great confidence in this being a long lasting repair.  On this instrument, I do not want to replace the supports with traditional lyre sticks.  It is on a raised stage in a small theatre and I do not want to drill into the poly finish.  The pedal lyre is at face level for the audience and anything I do down there will be quite visible.  I may epoxy that hinge joint so it cannot move.  Is there any reason it needs to be hinged aside from factory production ease?  What has worked for you?<o:p></o:p></span></font></p> </div> <div> <p class=MsoNormal><font size=2 face="MS Sans Serif"><span style='font-size: 10.0pt;font-family:"MS Sans Serif"'> <o:p></o:p></span></font></p> </div> <div> <p class=MsoNormal><font size=2 face="MS Sans Serif"><span style='font-size: 10.0pt;font-family:"MS Sans Serif"'> <o:p></o:p></span></font></p> </div> <div> <p class=MsoNormal><font size=2 face="MS Sans Serif"><span style='font-size: 10.0pt;font-family:"MS Sans Serif"'>Bruce Dornfeld, RPT<o:p></o:p></span></font></p> </div> <div> <p class=MsoNormal><font size=2 face="MS Sans Serif"><span style='font-size: 10.0pt;font-family:"MS Sans Serif"'><a href="mailto:bdornfeld@earthlink.net">bdornfeld@earthlink.net</a><o:p></o:p></span></font></p> </div> <div> <p class=MsoNormal><st1:place w:st="on"><st1:PlaceName w:st="on"><font size=2 face="MS Sans Serif"><span style='font-size:10.0pt;font-family:"MS Sans Serif"'>North</span></font></st1:PlaceName><font size=2 face="MS Sans Serif"><span style='font-size:10.0pt;font-family:"MS Sans Serif"'> <st1:PlaceType w:st="on">Shore</st1:PlaceType></span></font></st1:place><font size=2 face="MS Sans Serif"><span style='font-size:10.0pt;font-family:"MS Sans Serif"'> Chapter<o:p></o:p></span></font></p> </div> </div> </body> </html>
