The bridge pins and strings touching the bridges were coroded and rusted after a few years.<br> <br> I would bet that restringing again would only temporarily address the symptoms.  Re-capping the bridge is probably the real solution to the problem.<br> <br> Jurgen Goering<br> <blockquote type="cite" cite="mid200502010400.j1140MB21135@bridget.rudoff.com"><br> <meta http-equiv="Content-Type" content="text/html; "> <meta content="MSHTML 6.00.2800.1479" name="GENERATOR"> <style></style> <div><font face="Arial" size="2">A small grand I recently serviced is showing severe rust/corrosion at bridge pins and across the deck of the bridge. This is a 90 year old 5' Fischer that was restrung only 6 or 7 years ago. It appears that no bridge work was done, i.e. new pins, cap, ect. There is no corrosion anywhere else on the wire. Ideas as to what would cause this? Bass strings are beginning to break at the front bridge pin. I am not so concerned about this piano (too late) as I am in learning what caused this for my own education.</font></div> <div><font face="Arial" size="2">Fenton Murray, RPT</font></div> <br> <br> </blockquote> </body> </html>
