Hello Everyone, first post about a first clock repair so please bare with me if I use the wrong terminology. I picked up a pendulum wall clock at an auction recently, basically house clearance type stuff so not much money, thinking if it works I will put it on the wall and if not it will be a fun project. It was listed as late 19th century, so I have no real idea of its real age or maker. I'm in the UK so 99% chance it is UK made. It was filthy and covered in oil so did not run. I stripped it down cleaned and reassembled. I have had it running continuously for over a week now and it keeps pretty good time.
My problem is with the chiming. It will every now and again miss a chime so that when it does chime, it strikes the wrong hour of half hour. For example it misses half past six and then strikes half six at seven o'clock, then seven o'clock at half past seven and so on.
It does not skip at any particular time. Sometimes it will skip once or twice a day and sometimes it will run for a couple of days without skipping at all. When I have been near it when it has missed a chime it only takes the slightest touch to one of the wheels arrowed (warning wheels?) in the picture below or even a little tap to the clock itself and it will turn again. I can see no obstruction and no rough or broken teeth. The uppermost wheel in the drivetrain that meshes with fly and the fly itself have a little wear at the pivot points. Is this just a case of a bit of wear causing a random jam?
Thanks for any help,
Steve
P.S. I have taken the hammer off in the pictures for a clearer view.
