This is slow motion vid of David Walter's amazing (D)W5 free pendulum clock, his interpretation of Philip Woodward's amazing W5 clock movement. The movement is showing a "miss", where the impulse to the slave pendulum on the right was not in synch enough to allow the Z shaped spring to catch. Hits and misses usually alternate.
I only read slow motion at the end, i was wondering how long that piece of fused quartz was, I had to import 4ft lengths from the US as no-one in europe makes in in longet than 1m . nice work. beautiful action, i will need to watch it several times again. whats the bob, type metal ? shape?
