[GreenKeys] Off topic you say? Here's your off topic!

I have not been following these posts about the clocks, but I do know that the tall WU clocks sometimes had mercury in the pendulum.  The standard wall ones did not.  

The first thing I sold on ebay was my WU clock which was getting rusty in my basement office.  It went for $80 I think and that was about 15 years ago.

Been there done that...............

I have about 12 of those clocks in my house.  I use Rado Shack D cell 
combiners to get the 3 volts for the winders and double stick them on the 
base.

I use 4 volts from a relay that keys the clocks on the hour to "zero" out 
any error.  Most are within a second or two when the pulse comes thru.

The correction pulse comes from an ESE master clock.  I seet it every few 
months from WWV.  The master is good for about a second every 4 months.

At my radio station, WRNJ, whe have a bunch of them too with the sweep 
second hands.  Same set up but using a 2N3055 to key the 4 volts to the 
corrector solenoid.  That pulse comes from the GPS clock that keeps the 
computers happy.

ESE clocks all have a solid state "relay closure" when the hour comes up. 
It's one second of closure.

We combine the WU clocks with the AP Model 15 that uses HeavyMetal to get 
the AP headlines on the hour.
