I've heard of this Andrew, but not tried it. I tend to lift this segment instead (hook right up against the agraffe). Then obviously you have to re-check string level on the speaking side. Usually how it works, is after doing (what I think is) a very thorough string leveling, I discover agraffe noises in the tenor. (most often pianos of certain makes and model years, that haven't been re-strung) Then I have to lift on the front side to overcome the noise. Beware of pianos with bushing cloth woven on the non-speaking side of the agraffe. Mark Cramer, Brandon University PS never re-string without servicing all bearings and terminations. :>) -----Original Message----- From: caut-bounces at ptg.org [mailto:caut-bounces at ptg.org]On Behalf Of Andrew Anderson Sent: Wednesday, April 05, 2006 8:01 AM To: College and University Technicians Subject: Re: [CAUT] Baldwin SD I've run into a Baldwin doing something similar. Does pressing down with a screw driver on the front segment (between agraffe & pin) aleviate the ringing? I've heard of tapping the screw driver down on the strings on the non-speaking side of the agraffes to put a little bend there that reduces the contact point. Particularly where there is a steep exit from the agraffe. Anyone else try this?
