Bruce:

With brass rails the center pins are held in place with butt plates,
not a hammer butt center. The center pins can work their way sideways
as the butt plates loosen over time and allow the hammer to travel a
bit sideways. I serviced one that was so bad the bass hammers were
sounding the neighboring notes. It was necessary to repin all the
butts. Check your pinning and correct any problems before bending
shanks, which would be the next step.
