Hi Joe I just did that to a bass bridge in a piano I own. Meissner 52" upright. This is because there was so much negative bearing, the bridge cap (in sections) was pulled off (after being glued down with CA). Don't ask why I did not determine bearing before I did ANY bridge repair. (So I could call myself idiot) Just don't do it yourself. Anyhoo, what could be an instant fix but to run a piece of piano wire behind the front bridge pins. I know, this is blasphemy to the idea of the relation of the string to the bridge pin and the cut, and besides the string would then ride up on the B pin and beat. But soon the pudding was proofed. I got an astonishing increase in sustain time of some of the crudiest sounding bass strings outside a square piano. Other strings sound OK, but I believe this to be a fault in the bass scaling. I had not heard of this procedure, so thought I had dreamed it up. I did not put a wire behind the back pins. Now all I have to do is cut out a section of the wire and see if the difference is audible. ---------- > From: Joe & Penny Goss <imatunr@primenet.com> > To: pianotech@ptg.org > Subject: Bridge repair > Date: Friday, April 24, 1998 10:32 PM > > List, > today I encountered a repair on an upright piano that has me stumped as to > its quality and or correctness. > > The repair looks to be about 50 years old and the piano about 75 years > young. > The repair.
