whacky hammers

<< Hey, list
      What causes a section of grand hammers to bounce around when you
 strike a note hard?  I thought it would be the studs setting, so I
 adjusted them but nothing happened.

Hi, Ben,

Assuming the action to be bedded front, center and back, and that the stack
screws are tight, one possibility is flexing of the hammer rail. There's
quite a bit of torque on it as the inertia of the hammer & shank resist the
upward motion of the jack, particularly with heavy hammers, and some rails
are more limber than others.
