I’m interested in knowing what people use to make sure it doesn’t move.  It was a longer piece that extended the entire treble area.   It was a slippery little thing that moved when the tension was brought up to pitch.   jeannie   <div>   Jeannie Grassi, RPT Registered Piano Technician Island Piano Service Bainbridge Island, WA 206-842-3721 <a href="mailto:jcgrassi@earthlink.net">mailto:jcgrassi@earthlink.net</a> </div>   <div> <div class=MsoNormal align=center style='margin-left:.5in;text-align:center'> <hr size=2 width="100%" align=center tabindex=-1> </div> From: pianotech-bounces@ptg.org [mailto:pianotech-bounces@ptg.org] On Behalf Of Barbara Richmond Sent: Thursday, March 09, 2006 1:40 PM To: Pianotech List Subject: Re: v-bar/capo repair </div>   <div> Hi David, </div> <div>   </div> <div> When experimenting duplex length with brass half or oval round, would you, in this case, place anything on the bottom of the brass to avoid scratching the plate?   Or isn't it a problem? </div> <div>   </div> <div> Thanks, </div> <div>   </div> <div> Barbara Richmond </div> <blockquote style='border:none;border-left:solid black 1.5pt;padding:0in 0in 0in 4.0pt; margin-left:3.75pt;margin-top:5.0pt;margin-right:0in;margin-bottom:5.0pt'> <div> ----- Original Message ----- </div> <div style='font-color:black'> From: <a href="mailto:davidlovepianos@comcast.net" title="davidlovepianos@comcast.net">David Love</a> </div> <div> To: <a href="mailto:pianotech@ptg.org" title="pianotech@ptg.org">'Pianotech List'</a> </div> <div> Sent: Tuesday, February 28, 2006 10:25 PM </div> <div> Subject: RE: v-bar/capo repair </div> <div>   </div> Like Ron N. says, I think it’s likely it has to do with the front duplex and you may be able to shorten, detune and increase the deflection angle by inserting some brass of appropriate dimension—at least you can experiment.  If it turns out that that’s the problem, it’s not that big a deal to remove the strings from one section and insert the new counterbearing piece and then replace the strings (the same ones you took off).  Unhook them from the tuning pins slip in the brass or whatever and then reattach—if that proves to be the problem.  I get brass of varying sizes from <a href="http://www.rjleahy.com/">www.rjleahy.com</a>.  They will cut to a reasonable shipping size.  I don’t know the configuration of this piano but maybe you can send pictures and some suggestions could be made by various people, I’m sure.  If the noise disappeared originally by muting the front duplex, it is likely that there is leakage occurring and that’s what you should address.  Shortening the section and increasing the deflection can do that.  You do want to be sure that the angle and deflection work together.  The longer the duplex the greater the deflection angle.  Similarly, a shorter duplex requires smaller angle.   <div> David Love davidlovepianos@comcast.net </div> </blockquote> </div> </body> </html>
