After a long pause I have returned to testing the clock mechanism. I have made some repairs to the components that make the chime work at the right time and for the right number of bings of the bell. One lever had been repaired a long time ago, but the repair had failed. A spring was also rather bent and not acting well enough.

I suspect that the original repairs may have been made by my great grandfather who once owned the clock!

Initial tests show that it chimes correctly, but it needs to be run through quite a few cycles to have some confidence that the repair has worked.

This is the insides of a grandfather clock. It had stopped, but will chime again, after some fettling. You can see evidence of old repairs (as well as evidence of age). I suspect that my great grandfather had something to do with some of the repairs.
