The pendulums weights, in a bucket suspended from a crane-style arm, act as the clocks power source. The weights propel the pendulum from vertical post to vertical post. As it flies it turns precision gears which in turn keep time. To speed up or slow the clock, adjust the weight-balance of the pendulum by adding or removing weights.
