Sohmer Bridge Agraffes

[Larry J. Messerly]

We had a good chapter meeting this month on replacing broken agraffes and
repairing botched jobs.

The subject of Sohmer Bridge Agraffes came up with discussion on how to
rid a piano with these of false beats. (Other than replacing the bridge.)

Why do these agraffes cause false beats and not the ones on the harp?  Is
it the regidity of the harp, the angle of up-bearing of the string going
to the tuning pin?  It was agreed upon that it is not because the agraffe
is loose in the wood.

My thought was to add side bearing to the string as it goes through the
bridge agraffe by inserting bridge pins in the center of the bridge to
pull the string to the side of the hole in the agraffe.  (Increasing the
height of the string passing over the bridge behind one of these agraffes
would probably not be a good idea.)

Suggestions?
