Hello,
I thought this Lenzkirch clock I repaired was good to go.
I was wrong.
It stops after ~5 days and always 10 past the hour.
The cause is that the strike/chime does not have enough power left to start.
The spring is run down.
I can see that this spring can only wind almost 7 half turns of the key.
However, the clock spring can wind over 13.
Almost double.
I think this has to be the wrong spring.
It has not been shortened as the barrel is very full.
Does anyone know how I can work out the correct spring for this clock strike barrel?
Did Lenzkirch use identical springs for clock and chime/strike?
Both barrels are the same size.
The movement is marked Lenzkirch 52
Best regards
Bernt
