Antique Clocks/japy freres


Hi I hope you can help
I have put back into working order an old family slate french mantle clock.
But the striking is playing up.When it strikes it is very rapid and only works on the low number hours.
My thought is that the FLY is the problem.
My question is should the FLY be rigidly fixed onto its shaft, currently it is very sloppy. If it should be fixed can I just solder it on or should it be a sliding fit and if so how can I achieve this?
I am only a amateur and you thoughts would be very helpful.
Thank you in advance

The flywheel or fan has to be able to spin freely on the staff. This is because at the end of the chime cycle a lever drops in the path of a pin which provides a very abrupt stop for the chime movement. The fan then spins a half a turn or so thereby reducing the stress on the movement.

You will probably have to remove the fan staff from the movement and then remove the fan from the staff then give the fan a little squeeze with pliers and reinstall it. Put the fan back on the staff and check how tightly it fits. It should turn with a moderate amount of resistance in the fan but should not be loose like you describe it.

It is best to let the clock run until the springs have exhausted much of their energy before removing the fan. It should be possible to remove it without completely disassembling the movement.

I can not think of any questions I cannot answer in regard to repairing antique clocks or radios. However, I am sure there are a few I have not heard and may not be able to answer. If I cannot, I will say so. I have been repairing them since I was a young child.


My experience includes repairing CooKoo clocks, Westminsters, BimBam, almost all antique clocks. I do a bit of repair on battery clocks where the value is sufficient to warrant working on them. I also repair antique (tube type) radios - all makes.
