> 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
Google just found this:
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. I hate spam.
