<VV> Clock: Tick-Tock & Clunk

[Jim Houston]

Yes...  the "clunk" is the winding mechanism..  inside the clock is a 
relay with a set of points.  One side of the points is attached to a 
spring.  When the points contact each other, current flows through a 
coil and causes the side with the spring to move away from the other 
point (and applying spring tension at the same time).  The spring 
tension drives the arm back toward the other point (tick, tick, tick) 
and when they touch - "Clunk!" tick, tick, tick, ...  hope this 
explanation is clear enough...  I think if you set the clock by going 
all the way around, it will 'adjust' to run a bit faster.  Might take 
several adjustments...

Good luck,
