This clock was designed as a spring driven shelf version of clocks WC2 and WC5. The design intent was to come up with a spring driven wooden clock which would run 7 days between windings. It was designed to be driven by a constant force "Tensator" spring. The design was abandoned when it was decided that the power required to run the clock would be too great to run it safely with the springs currently available on the market.

The gearing is currently designed for a pendulum swinging at 93 1/3 beats per minute which should work no matter what spring is selected to drive it. This odd number was selected to make the pendulum the correct length to fit into the case and at the same time allow the clock to have a second hand.

If a suitable spring can be located, the gearing between the great wheel and the minute wheel will be redesigned to accomodate the new spring, then the working parts will be fabricated and assembled on a test stand to determine the actual torque required to keep the pendulum swinging. This will be done on the test stand shown to the left.

IF ANYONE KNOWS WHERE TO FIND A LONG, MEDIUM TO LOW TORQUE TENSATOR SPRING, PLEASE EMAIL ME THE INFORMATION SO I CAN RESURRECT THIS DESIGN.
