I went back in the archives and found the original post: "Oh Wiser-than-I Ones, (of which there are multitudes!) I heard a "zinging" in the attack of a low tenor string on a customer's = piano. She heard it, too, and didn't like it. (Turned out a little = needling on the hammer at about 1 o'clock and 11 o'clock softened that = attack nicely) Upon close inspection I notice an anomaly in the way the = bridge was notched. It's the right string of the lowest plain string = unison. I was wondering if I might elicit a few opinions about the = looks of this. I've attached a photo -- I hope it comes through! The bridge isn't notched all the way across on that right-most pin. On = the side that the string bears there is certainly a good notch, but to = the right of that it's not. Seems like that would actually strengthen = rather than weaken the pin's hold, but since it looks unusual I thought = I'd ask. Extending upward from the un-notched edge there is a visible = line. That's the border of the notching. It is not a crack. This is a = fairly new piano, about 3 or 4 years old, a Knabe Studio Upright." Thanks, John Dorr Helena, MT After reading it again..."On the side that string bears there is certainly a good notch, but to the right of that it's not", I can see where Ron's coming from... When they notched, they left the end of the bridge unnotched. It isn't touching the string...there's a good notch...voicing took care of the problem...the whole question was about the little un-notched part of the bridge...jeesh....I know, I contributed to the post also but that was only cuz I didnt' read the original post carefully...;-] David Ilvedson, RPT Pacifica, California ----- Original message ---------------------------------------- From: "Ron Nossaman" <rnossaman@cox.net> To: "Pianotech List" <pianotech@ptg.org> Received: 2/25/2006 11:28:44 PM Subject: Re: Bridge Notch Anomaly >> The area is too small for most chisels to get to. >> >> David Love >> davidlovepianos@comcast.net >> >> >> Why not just use a chisel? >> >> William >Boy, this sucker went south pretty quickly.
