Hi Evan, if the clock is running 30 mins fast in 24 hours then you might have enough adjustment on the pendulum, undo the pendulum nut so the pendulum is at its lowest position on the rod and then see what you get, if it is still running fast then you can try a longer suspension spring. If it is still running too fast then it could indicate that the pendulum rod has been shortened and you may need a new one. The only other reason for running too fast could be the escape wheel tripping through the pallets if the depth has been set incorrectly or you may have a short tooth/teeth on the escape wheel. Just watch it for a few minutes while the clock is running and see if you get the odd occasion when a couple of teeth get through instead of one at a time. If this is not happening then start looking at the other stuff.

Thanks for the tip. I was able to lengthen the pendulum bob enough so it’s within about a minute a day. Further tweaking should dial it right in.

Any suggestions for fixing the chime? The symptom is that it chimes correctly on the hour and 1/2 hour, but the number does not correlate with the hour, i.e. sometimes it rings once on the hour, and sometimes it rings 4 times when it’s 1:30. The chime does increment, so it’s acting like it’s running faster than the movement, yet still triggers on the hour and 1/2 hour.
