This is a 90 year old 5' = =3D Fischer that was restrung only 6 or 7 years ago. It appears that no =3D bridge work was done, i.e. new pins, cap, ect. There is no corrosion =3D anywhere else on the wire. Ideas as to what would cause this? Bass =3D strings are beginning to break at the front bridge pin. I am not so =3D concerned about this piano (too late) as I am in learning what caused = =3D this for my own education." Fenton, This has all the earmarks of DMSO use by the pianist! I've had to = contend with this a couple of times. Check to see if the pianist has = Arthritis, or some other debilitating body problem. And, if they are = using DMSO to ease the pain. DMSO,s original use, was to thorougly clean metal. It cleans metal so = well, that is promotes rust. Best Regards, Joe Garrett, R.P.T.
