Clock Number 9

Clock Number 9

This is the smallest and also the first non pendulum clock I have built. The idea of using an air solenoid developed from a clock I saw on the net called the Lazy Clock which moves the hands each minute. I wanted to make it more interesting than that and use a 30 teeth count wheel. I understand that the original idea was used by a Russian horologist about a hundred years ago. I use an integrated circuit (see electronics) to control the air solenoid with a 20mm by 6mm magnet as the driving force. While it works quite well it is a bit noisy and I may modify it some stage and install the more successful lever system that I used in clock 10. .

Base, top and posts with holes drilled.

Inserting scallops into the legs.

This is the frame assembled and checked to ensure it is square.

Movement - rear view This is the rear view of the movement. The coil has been wound around a 6mm piece of brass tube.

Side view of the movement. The coil has been covered by a wooden bell and the magnet pops up and down.

The posts and dial ready for assembly.

Turning a square top. In order to turn the squared top, the sides are covered in pine using a paper glued joint. After the top is turned, it is turned over re-jigged and then hollowed.
