Originally designed to be used in the mechanism, which is the mechanism pinion polishing legs relies on two steel legs. Alternating rock smash the Cog which collision gear frequently, easy-wear gear. Therefore, changes to the mechanism of pendulum collision polishing options. When the pendulum swing smash one polishing options Polishing options it will release, and make the mechanical gears rotate into it for a while. But the mechanical gear bracket will go against another polished legs. Enough, the pendulum will eventually drop, bounce, another sliding leg scrub all mechanical gears, this is connected to an enclosure made from pulleys, weights, Aboriginal. When it's time to hoist tongkwan periodically using the pendulum in this Chamber, there are four meters long and weighs 300 kilograms of swinging go back to using 2 seconds on the pendulum are British penny coins to plug timing. If you have a lot. The center of mass moves upward, resulting in a shorter period of swing (a pendulum swinging faster). On the other hand, if removed, it will get very step swing period (pendulum swinging slowly.)
