<HTML> <HEAD> <TITLE>Re: [CAUT] Agraffe noise</TITLE> </HEAD> <BODY> Bob, Dan G from Humboldt, Try loostening a string so that it can be lifted with a string hook 1/2&quo= t; into the speaking length, lift 'til the string segment is approximately 3= 0-45 degrees and rock the string/hook toward the bass and treble burnishing = the hole on the speaking side of the agraffe. This has worked on the Ds and = Bs at Humboldt. Miss you in H. County Dan on 9/13/04 9:25 AM, Robert Callaghan at robert.callaghan@harmonicity.com wr= ote: <BLOCKQUOTE>Dear List, I just started at the local college.  There is one grand piano there w= here many plain wire strings and a few bass have a very loud hiss or sizzle.=  If is was a bass string you'd think the copper wrap was loose, but tw= isting the string didn't help.  It is the worst case of this I've ever = seen. The piano has signs of being worked on.  Beside pieces of felt stuck h= ere and there trying to get rid of the zinging,  there are Pin-Tite sta= ins on the plate and rock hard, overly lacquered hammers. On other pianos I'= ve had good luck tugging upwards on the string, or cleaning out the hole in = the agraffe.  But that hasn't helped in this case. If I push down firml= y on the string on the tuning pin side of the agraffe it stops.  There = is felt there so it isn't a vibrating string. In my research I found a Jo= urnal article that mentions that maybe the agraffe itself is loose. I wanted to run this by you all before I began testing this theory, or perh= aps someone knows exactly what the problem actually is.  (And because I= have the piano faculty looking over my shoulder I  want to be right th= e first time!) Thanks for any insights. Bob Callaghan </BLOCKQUOTE>             </BODY> </HTML>
