Do you need a mainspring Winder?
You don’t need tools like mainspring winders because you can fit the new mainspring. This will save you a substantial amount of money because these tools are expensive. There’s no risk of the old mainspring breaking after a while, so you avoid having to repair the watch and service it again.
How do you use a mainspring Winder?
Be very careful just wind it back a few until until you feel the resistance. Go. And that’s it it’s done.
How do you make a clock a mainspring Winder?

How do you put down a clock mainspring?
If you don’t hold it tight. So I’m going to rotate. This to move that click out of the way and then I’m a very carefully and gently allow that ratchet to unwind with the click out of the way.
How does a mainspring work?
The mainspring is wound by turning the arbor, but drives the watch movement by the barrel; this arrangement allows the spring to continue powering the watch while it is being wound. Winding the watch turns the arbor, which tightens the mainspring, wrapping it closer around the arbor.
What means main spring?
Definition of mainspring
1 : the chief spring in a mechanism especially of a watch or clock. 2 : the chief or most powerful motive, agent, or cause.
How do you measure a watch for a mainspring?
If you need to calculate the length of a mainspring, you can use the following formula: Mainspring should only occupy ½ of the barrel. Square the radius of the inside of the barrel and multiply by Pi (3.1416). Square the radius of the barrel arbor hub and multiply by Pi (3.1416).
How do you remove a mainspring from a barrel?

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.
What happens to an overwound clock?
Over the years, the grease will become dry and sticky, and the mainspring may become rusty or corroded. These factors cause friction in the movement of the spring coils. Eventually the spring becomes so dry and gummy that is can’t release anymore, or the spring metal becomes worn out and corroded and may break!
How long does a mainspring last?
The mainspring in the common 1-day movement is calculated to enable the watch to run for 36 to 40 hours, i.e. 24 hours between daily windings with a power-reserve of 12 to 16 hours, in case the owner is late winding the watch.
How do I know what size my mainspring is?
When was the mainspring invented?
about 1450
Solution of the problem was advanced almost as soon as the mainspring was invented (about 1450) by the application of the fusee, a cone-shaped, grooved pulley used together with a barrel containing the mainspring.
How do you size a clock mainspring?
Measuring is done to get the size of the new mainspring to match up to the old one. Measure the width first, then measure the thickness with a micrometer. Then the final measurement is the approximate length. Take all those numbers and compare them to the chart.
How long is the mainspring in a watch?
20–30 cm long
A modern watch mainspring is a long strip of hardened and blued steel, or specialised steel alloy, 20–30 cm long and 0.05-0.2 mm thick.

How do you tell if a clock is overwound?
Often, one sees clocks advertised on Ebay and elsewhere as “not running, probably overwound.” The fact is, there is no way to overwind a clock. Specifically, if a clock is wound fully, eventually the winding key will no longer turn.
How do I free my 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 I free up my overwound clock?
Should you oil a clock spring?
The mainspring is the heart of the timekeeping of any spring drive clock. If the mainspring is not oiled properly the clock will not work. The oil that is used is absolutely critical ; it must be able to work in a slow moving environment and it must be able to resist evaporation for many years.
Does leaving an air rifle cocked weaken the spring?
Well, if you do leave the air rifle cocked for a long time, the spring will weaken. With as much as a 6% loss of velocity after just 4 weeks. The longer the air rifle is left cocked, the more damage the spring will undergo.
What is unbreakable mainspring?
Self-winding watches and ‘unbreakable’ mainsprings
A semicircular weight, pivoted at the center of the watch, rotates with each wrist motion. A winder mechanism uses rotations in both directions to wind the mainspring. In automatic watches, motion of the wrist could continue winding the mainspring until it broke.
What is a mainspring bridle?
The outer end of the mainspring, instead of attaching to the barrel, is attached to a circular expansion spring called the bridle that presses against the inner wall of the barrel, which has serrations or notches to hold it.
How does a clockwork spring work?
How Does it Work? The inner end of the spring (arbor) is fixed over the shaft of the mechanism, with the outer end being attached to the barrel. The arbor is turned to wind up the spring. It releases energy when allowed to uncoil.
