Can an over wound clock be fixed?
Most likely problem: In actual fact it is almost impossible to overwind a clock.
Once the coils of a flat mainspring are in firm contact with one another, than the spring can not be physically wound any tighter.
The only way to truly overwind a clock spring is to turn it so tightly that the spring actually breaks.
How do you fix a clock that has been wound to tight?
When you do wind your clock, just make sure you have a tight fitting key and that it is inserted all the way. Turn the key slowly and just a half turn at a time. Wind it up until it stops. Do not try to force it to wind any further.
Can you unwind a clock?
To unwind the clock you will obviously need the key. Unwind the carriage clock in half turns and release / apply the ratchet between the turns so that the spring pressure is always managed by either your fingers with a firm hold on the key, or by the ratchet being allowed to stop the backward movement.
Why has my pendulum clock stopped working?
The reason a clock pendulum often stops swinging, after being moved, is because the clock case now leans at a slightly different angle then it did at its former location. A clock is “in beat” when the tick and the tock are evenly spaced.
