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 www.rjleahy.com <http://www.rjleahy.com/> . 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.=20 =20 David Love davidlovepianos@comcast.net=20 -----Original Message----- From: pianotech-bounces@ptg.org [mailto:pianotech-bounces@ptg.org] On = Behalf Of Barbara Richmond Sent: Tuesday, February 28, 2006 7:51 PM To: Pianotech List Subject: Re: v-bar/capo repair =20 Hi David, =20 Well, I'm not sure if the capo hardness was ever right since the problem = was there before it was restrung, also. The problem didn't surface until = the piano was a year old or so. Then it took about the same amount of time = for the problem to surface after it was restrung. It was the repetition of = the timing and the symptoms that got my attention. =20 Thanks for the suggestions of inserting the brass half round or half = oval. I will try that. BTW, what sort of establishment would carry those? =20 Barbara Richmond ----- Original Message -----=20 From: David <mailto:davidlovepianos@comcast.net> Love=20 To: 'Pianotech List' <mailto:pianotech@ptg.org> =20 Sent: Tuesday, February 28, 2006 9:33 PM Subject: RE: v-bar/capo repair =20 Are you sure it's a soft v-bar? How much material did the stringer take off? Is it possible he actually filed through the hardened section? = How long and what is the angle of the counterbearing section?

You = might experiment by inserting a cut piece of brass half round or half oval underneath this section to see if that doesn't help. Have you looked at = the v bar with a mirror to examine its shape?

Paul Revenko-Jones has a fine class on this. Maybe he could send you his handout sheets. You might also try moving the strike point on those notes.

Sorry if I'm starting to sound like a = broken record. Here's the story: I serviced this piano when it was new. Not = long into its life, it developed a noisy duplex at the low end of the treble section. I muted it off. I tuned it for a few years, I moved away... =20 I moved back. In the meantime, the piano was restrung. I started = servicing it again a year after it was delivered. 9 months into servicing it, the noisy duplex returned in the exact same spot--but add another note. I freaked out (not in front of the customer), the customer freaked out, = too (not in front of me). I contacted the rebuilder who said he filed the = capo. He and I came to the conclusion (whether we are correct or not) that it = is a case of soft cast iron. I looked up hardening cast iron in the = archives. To do that would mean taking the plate out of the piano and that's not = an option. I'm convinced if I refile the capo, the same thing is going to happen again. =20 =20 I know there are some pianos that have some sort of rod installed at the v-bar. Is it possible to do the same with this piano at the capo? Has anyone done it? Do you have detailed instructions? Will someone hold = my hand?.....Please? =20 Thanks, =20 Barbara Richmond, RPT ---------------------- multipart/alternative attachment An HTML attachment was scrubbed...
