    Hi Ruben: You'll need a micrometer to measure the overall diameter of the other string, plus the diameter of the core. You'll have to measure the length of the string from the agraffe to the hitch pin, and the length of the speaking section from agraffe ...

    I may be "hijacking" this thread, but I would like to inject a related question that bears discussion: Recently I have tuned at least two pianos that were new or very near new Chinese grands that I was quite impressed with (Hallet, Davis and Kohler Campbell?). ...

    Wim I agree, this is not the time to get into the new piano market. Here in Seattle the economy is red hot. There are more tower cranes (about 17) building apartments, condos and businesses than any other city in the United States. I have a close ...

    Dave Just for curiosity, why are you considering selling new high end pianos, and then only one or two at a time? The new market is very slow right now, all over the country, and people are just not buying expensive instruments anymore. Yes, some here ...

    Bill, I know exactly what you are talking about. I had that problem on a Model O, somewhat older (1907 or something like that). I ended up carving out the backchecks. However, perhaps if you change to the vertical wire install that is now standard ...

    Thanks to everyone for your replies, very much appreciated. It's most likely the damper leads. I don't have the $197 lead pliers (looks like only S & S sells them), though as someone here said I could use my fingers to settle the leads in place. I deferred ...

    The one good thing is that the group doing the Crumb piece is top-flight: see stringtheorymusic.org/concerts/2016-2017/april-18-2017/ [ I left off the http so that the entire page doesn't load into this message]. Hopefully they have a lot of experience ...

    I'm installing a new Stwy back action in a 1920 M, and following David Hughes' excellent protocols, measured the old and new distances (to the keybed front) of the underlever noses and sostenuto tabs. It turns out that the new tabs have moved 1/4" forward ...

    sorry to disappoint anyone but it is not an 1860's . Not sure if an 1860's would have the wing shape so chances are that vintage would have been a square grand...I doubt anyone will be willing to put the money into it as a piano but you never know... ...

    Giovanni, Does it make the noise without the damper installed? Assuming you've checked for a loose flange screw. And pinning problems. Loose leads? If this piano has springs up that high, could one of them be contacting something it shouldn't? Margie ...

    An 1860's Knabe Grand would be quite a discovery (if they were made at all that early). It would clearly have pre-modern action parts and less than 88 notes. In the early 20th century Knabe made small art case grands with square tail cases. Many of these ...

    If I were at this clients house, I'd tighten the underlever flange screws and test for loose leads. If the lead is loose you'll be able to click it back and forth between your fingers. If you don't have pliers to suage, you can use your rep spring tool ...

    It's easy to test whether the lead is loose, since it is so conveniently inserted right at the front. Put a little bit of CA glue on a small screwdriver, and butter the seam at the edge of the lead weight, so the CA wicks in. You'll have your "yes ...
