<HTML>Greetings,             &nbs= p; I was called to tune a PianoDisc grand piano mfg'd by Young Chang. Findin= g c#63 seized, I removed the action drawer only to find a sostenuto flange l= odged there, causing the problem. It was removed easy enough, and the key pl= ays fine, but how does one re-pin the flange back in the trapwork? &nbs= p; I know how to re-pin, however I never removed the trapwork on a grand. Is= this a common occurance that one of these pops out, or did I come upn the o= bscure? Piano is owned by a small hotel. The owner claims it happened while it was = being played for a wedding.
