<HTML><BODY style="word-wrap: break-word; -khtml-nbsp-mode: space; -khtml-line-break: after-white-space; ">Good point Susan. I'm really sure if it is the coupling or pulling. I do not squeeze the couplers very tight but I suppose installing four might be pulling the strings together ever so slightly. I have had a good deal of success installing the couplers on the front bearing segments in the treble sections so I thought why not try installing in these tenor problem segments as well.<DIV><BR class="khtml-block-placeholder"></DIV><DIV>Don<BR><DIV> <SPAN class="Apple-style-span" style="border-collapse: separate; border-spacing: 0px 0px; color: rgb(0, 0, 0); font-family: Helvetica; font-size: 14px; font-style: normal; font-variant: normal; font-weight: normal; letter-spacing: normal; line-height: normal; text-align: auto; -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; "><SPAN class="Apple-style-span" style="border-collapse: separate; border-spacing: 0px 0px; color: rgb(0, 0, 0); font-family: Helvetica; font-size: 14px; font-style: normal; font-variant: normal; font-weight: normal; letter-spacing: normal; line-height: normal; text-align: auto; -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; "><SPAN class="Apple-style-span" style="border-collapse: separate; border-spacing: 0px 0px; 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; text-align: auto; -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; "><DIV style="font-size: 12px; "><BR class="khtml-block-placeholder"></DIV><DIV style="font-size: 12px; "><SPAN class="Apple-style-span" style="font-size: 12px; "><SPAN class="Apple-style-span" style="font-size: 12px; ">Don McKechnie</SPAN></SPAN></DIV><DIV style="font-size: 12px; "><SPAN class="Apple-style-span" style="font-size: 12px; "><SPAN class="Apple-style-span" style="font-size: 12px; ">Piano Technician</SPAN></SPAN></DIV><DIV style="font-size: 12px; "><SPAN class="Apple-style-span" style="font-size: 12px; "><SPAN class="Apple-style-span" style="font-size: 12px; ">Ithaca College</SPAN></SPAN></DIV><DIV style="font-size: 12px; "><SPAN class="Apple-style-span" style="font-size: 12px; "><SPAN class="Apple-style-span" style="font-size: 12px; "><A href="mailto:dmckech@ithaca.edu">dmckech@ithaca.edu</A></SPAN></SPAN></DIV><DIV style="font-size: 12px; "><SPAN class="Apple-style-span" style="font-size: 12px; "><SPAN class="Apple-style-span" style="font-size: 12px; ">607-274-3908</SPAN></SPAN></DIV><DIV style="font-size: 12px; "><BR class="khtml-block-placeholder"></DIV><DIV style="font-size: 12px; "><BR class="khtml-block-placeholder"></DIV><BR class="Apple-interchange-newline"></SPAN></SPAN></SPAN> </DIV><BR><DIV><DIV>On Apr 5, 2006, at 2:00 PM, <A href="mailto:caut-request@ptg.org">caut-request@ptg.org</A> wrote:</DIV><BR class="Apple-interchange-newline"><BLOCKQUOTE type="cite"><P style="margin: 0.0px 0.0px 0.0px 0.0px"><FONT face="Helvetica" size="4" color="#000000" style="font: 14.0px Helvetica; color: #000000"><B>From: </B></FONT><FONT face="Helvetica" size="4" style="font: 14.0px Helvetica">Susan Kline <<A href="mailto:skline@peak.org">skline@peak.org</A>></FONT></P> <P style="margin: 0.0px 0.0px 0.0px 0.0px"><FONT face="Helvetica" size="4" color="#000000" style="font: 14.0px Helvetica; color: #000000"><B>Date: </B></FONT><FONT face="Helvetica" size="4" style="font: 14.0px Helvetica">April 5, 2006 1:37:12 AM EDT</FONT></P> <P style="margin: 0.0px 0.0px 0.0px 0.0px"><FONT face="Helvetica" size="4" color="#000000" style="font: 14.0px Helvetica; color: #000000"><B>To: </B></FONT><FONT face="Helvetica" size="4" style="font: 14.0px Helvetica">College and University Technicians <<A href="mailto:caut@ptg.org">caut@ptg.org</A>></FONT></P> <P style="margin: 0.0px 0.0px 0.0px 0.0px"><FONT face="Helvetica" size="4" color="#000000" style="font: 14.0px Helvetica; color: #000000"><B>Subject: </B></FONT><FONT face="Helvetica" size="4" style="font: 14.0px Helvetica"><B>Re: [CAUT] Baldwin SD</B></FONT></P> <P style="margin: 0.0px 0.0px 0.0px 0.0px"><FONT face="Helvetica" size="4" color="#000000" style="font: 14.0px Helvetica; color: #000000"><B>Reply-To: </B></FONT><FONT face="Helvetica" size="4" style="font: 14.0px Helvetica">College and University Technicians <<A href="mailto:caut@ptg.org">caut@ptg.org</A>></FONT></P> <P style="margin: 0.0px 0.0px 0.0px 0.0px; min-height: 14.0px"><BR></P> <P style="margin: 0.0px 0.0px 0.0px 0.0px; min-height: 14.0px"><BR></P> <P style="margin: 0.0px 0.0px 0.0px 0.0px"><FONT face="Helvetica" size="4" style="font: 14.0px Helvetica">At 02:40 PM 4/4/2006 -0400, you wrote:</FONT></P> <BLOCKQUOTE type="cite"><P style="margin: 0.0px 0.0px 0.0px 10.0px"><FONT face="Helvetica" size="4" style="font: 14.0px Helvetica">For an experiment, I installed Pitch Lock couplers in that segment.
