Winding your mechanical pendulum clock is essential for keeping it running properly for as long as you want it to run! From its invention in 1656 by Christiaan Huygens, inspired by Galileo Galilei, until the 1930s, the pendulum clock was the world's most precise timekeeper, accounting for its widespread use. The advantage of a pendulum for timekeeping is that it is a harmonic oscillator: It swings back and forth in a precise time interval dependent on its length, and resists swinging at other rates. Purchase parts such as a pendulum. The first pendulum to correct for this error was the mercury pendulum invented by Graham in 1721, which was used in precision regulator clocks into the 20th century. powered by a battery, you wound it up with a key and there was a long side to side due to the force of gravity. This condition can often be heard audibly in the ticking sound of the clock. That's going to get tedious quite quickly, so what about automating weight called a bob hanging from a string) that swings from OOTDTY.

Animation: How the escapement works: 1) The falling weight powers the clock. Heres how to do it, step by step: Some clocks have only one spring; others have two or more springs in series so if you see more than one, there is usually no need to take them all off, but some people find it easier to clean and oil while theyre detached from their holders and hanging free anyway. I have the bottom nut screwed down as far as it goes with out it falling off. It will automatically adjust for the spring and fall time changes and drive large hands. Most quality clocks, including all grandfather clocks, have a "seconds pendulum", in which each swing of the pendulum takes one second (a complete cycle takes two seconds), which is approximately one metre (39 inches) long from pivot to center of bob. For instance, a clock with a heavier weight can store more potential energy, and can therefore run longer than a lightweight clock before any winding is required. 2) As it drops, the weight pulls the gears around. The timekeeping is regulated and adjusted by the movement of the pendulum.
