What to do when all the chime notes sound “thunky”

A customer received a new Hermle chiming wall clock, and when it chimed or struck, all the notes sounded bad because the hammers were too close to the chime rods. The fix was simple:

  1. Tighten the four nuts on the back of the case,
  2. Slightly loosen the two Phillips head screws on the back of the case,
  3. Move the iron chime rod base so that the chime rods are about 1/16 to 1/32 inch below the hammer heads,
  4. Securely tighten the two screws.
