There was an article in Scientific American Sep 74 describing a nice hack to 
synchronize a pendulum clock to a quartz crystal.  They attached a magnet to 
the pendulum and then pulsed a coil at the right time.  It was the typical 
Amateur Scientist level of detail.

Some pack rat on this list (I think) sent me a scanned in copy.  I can send 
it to anybody who wants it.
