Question
I have a grandfather clock with Westminster Chimes. We recently had it lubricated in my home, and it seems since then that the sound of the houly chime is flat and not the usual sound.Is there a way of adjusting this?

Answer
Hi Sarah,
The adjustment for getting the best sound from the chimes is in the hammers that strike the rods. Either they were bent when the clock was lubricated or the movement is not in exactly the same position on the seatboard as it was before. Usually the clock movement is held to the seatboard by two screws coming up from the bottom. See if the movement will shift from side to side or forward/backwards when you push it.
If you think the movement has moved from its original position you should move it back to where it gives you the best chime sound. The hammers should all be about 1/8" from the rods when they are in a rested position.
If the first option does not correct your problem move to the following step:
The second thing to try is to bend the hammer wires so that the hammer heads are 1/8" from the rods. Then listen to the chime and make small adjustments to the hammer wires so that each give the best sound.
