How is clock winding key size determined?
On the back of your clock is the winding arbor (the steel shaft the key fits on to). With your digital gauge, measure the square shaft from flat side to flat side to get the millimeter size. Most winding arbors taper out towards the the clock and the end section is most likely the smallest.
Why does my wind up wall clock keep stopping?
A clock that is out of beat is likely to stop because the pendulum is not receiving the optimum impulses to keep it swinging. If it’s badly out of beat it will stop within a few minutes. If it’s only slightly out of beat it could run for days but will eventually stop earlier than it should.
How do I fix overwound clock spring?
Fixing An Overwound Clock
- Clean The Clock. Sometimes cleaning your clock will get it working again.
- Lubricate The Mechanism. Like cars, all mechanical clocks need regular oiling.
- Replace The Springs.
- Find A Professional.
Why does my regulator clock keep stopping?
Ensure the clock hands are not touching each other. When the hands are touching it usually means they are stuck and your clock will not run. Look at the hour and minute hands closely. If they are touching the “time train” may be jammed which prevents the pendulum from swinging.
How do you start an overwound clock?
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. Even though it is impossible to over-wind your clock, it is also not necessary to wind it until the last possible click of the ratchet.
How do you open a regulator clock?
Use the nut at the bottom of the pendulum to rate the clock. Loosen the adjustment nut to slow the clock down or tighten the nut to speed it up. If the hands are sticking or meeting up at any time during the day, gently level them out over the face of the clock with a small set of needle nose pliers.
How do you wind a clock without a key?
If your clock has functional hanging weights and a pendulum, you won’t need a key for winding your clock. Instead, you’ll need to raise the weights using the special crank that comes with the clock. While you’re cranking the weights up to wind the clock, take care not to lift the weights by hand while doing so.
What are the two winding holes on a clock?
If there are two holes, one is for the time spring and one is for the hourly chime. Some clocks also have a third hole, which governs the quarter-hour chime tones. Movement length should be specified by the manufacturer in the original packaging when you buy the clock.
How does a regulator clock work?
Regulator Clock – The Works work. Some mechanical clocks are regulated by pendulums. Those clocks can’t be wandering around. The pendulum must swing an equal distance to each side of a center line that runs through the escapement. That center line needs to be plumb and fixed so it doesn’t move.
How do you set the regulator on a pendulum clock?
Regulators are set by increasing or decreasing the speed of the pendulum swing. 1 Synchronize the regulator clock to a known accurate time source such as the time displayed on a cellphone or computer. Rotate the minute hand only in a clockwise direction to set the clock hands to the time.
What is a Viennese regulator clock?
They started in England and swept to Vienna, where the mechanics of the regulator clocks where fine-tuned and built upon. The Viennese clocks became known for their stellar timekeeping. A regulator clock can seem a perplexing piece of delicate machinery when you open the back to get at the working pendulum parts.
How do you check the accuracy of a regulator clock?
Rotate the minute hand only in a clockwise direction to set the clock hands to the time. Wait 24 hours, then compare the time on the regulator clock to the time displayed by an accurate time source to determine any discrepancy in the clock’s accuracy. Stop the swing of the pendulum and hold the pendulum still in one hand.
