Academy 18157 Da Vinci Flying Pendulum Clock

SKU: ACY18157
The Flying Pendulum Clock needs no glue, paint or battery to finish and operate. Easy to build, it delivers a learning experience during assembly, and serves as entertainment when watching the completed timepiece operate. Da Vinci was fascinated by how timepieces operate. Based on one of his sketches, it uses the laws of motion and a vertical 'flying ½ pendulum escapement to keep accurate time.
The pendulum's weights, in a bucket suspended from a crane-style arm, act as the clock's power source. The weights propel the pendulum from vertical post to vertical post. As it 'flies ½ 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.
