[CAUT] Baldwin SD (agraffe noise)

[Mark Cramer]

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.

PS never re-string without servicing all bearings and terminations. :>)

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?
