Adjusting the Strike or Chime
If you feel the sound of the strike or chime is not right, you can adjust it simply by bending the arm on the strike hammers to bring the hammer head closer or farther away from the rod or bell. Usually, you should have about 1/4″ clearance when the hammer is at rest, so that it bounces away after striking the bell or rod, leaving it clear to resonate. Obviously, the harder the hammer hits, the louder the sound.
