> Has anyone looked at locking an old mechanical clock to precise time? The Amateur Scientist, Scientific American, Sep 1974, had an article on doing that to a pendulum clock.
They put a small magnet on the pendulum. It was out on a stick so it could poke through a coil without the pendulum or arm getting in the way. I asked about it on this list several years ago. You might check the archives. Somebody scanned in the article. I have 2 pdfs. One is 17 MB. The other is 300K but needs a newer pdf reader. One or the other may be online someplace. Google just found this: http://www.dealsdirect.com.au/p/wooden-wall-clock-pendulum-quartz-movement/ It's a pseudo old clock, but that probably solves all the mechanical issues. PS: You get some weird stuff if you google for >pendulum quartz<. -- These are my opinions, not necessarily my employer's.
