Thanks guys.   Got the info I had been looking for. This group is a great
resource!
Only purpose for this project is so that the Westminster clock chimes at the
same exact moment at the GPS driven UTC LED display in the lab shows the
quarter hour.
Why????

Why not!  :- )

Try:

and similar stuff found by googling "driving pendulum clock"
Lots of food for thought. Mumford has put some thought into it.
A lot depends on why you want to drive the thing; e.g. measuring
perturbations in the gravitational field, a sensitive barometer, temperature
sensor, etc. etc.
