re: Mantel clock 10

We have a guy down here who does wooden clocks he made the biggest wooden clock in the southern hemisphere, may be the world  in Nannup.  At 2 tonne it became a tourist attraction for the little town. It's made from local Jarrah and she-oak. It really is a work of art!!!!! I seem to remember seeing a reasonable sized wall clock that had a wooden mechanism but was powered by electro magnets acting on a pendulum so it kept great time.
