Greetings,

A long case clock I've owned for nearly 40 years requires repair, and in the spirit of lock down, I thought I'd have a crack at it myself. The first time I've attempted any clock repair that requires significant dismantling.

The clock itself is I think mid 19th century, full height, painted face. The engineering quality suggests the 'bog standard' end of the market.

The problem is that when I attempt to wind the chiming train, the ratchet doesn't catch and the weight descends immediately. Visual inspection indicates that a small black leaf spring has shattered.

From my distant Meccano days, I knew that the widget that locks a ratchet is called a pawl. However in clock spares lists, I have searched for the word in vain.

- Am I correct in thinking that the devices listed as 'click springs' are what I need here?

- My second query concerns whether I need to prepare to open up the core frame of the mechanism, or are there any clever tricks for replacing these things without doing that?

- And finally, if i do need to open up the mechanism fully, is there any standard protocol for putting these things back together again, aside from not bending anything or losing any bits?

Any YouTube instruction videos that can be recommended would also be appreciated.

Cheers..

Tom
