In writing up and email for 3DPPGH tonight I came across this.
https://groups.google.com/forum/#!topic/makerbot-clock-makers/6juXz6QGNGs
This particular message appeared to have some interesting linked content.
In addition the group itself could be another trove of hidden gems, and
it's public, if a little stale. Pay no attention to the makerbot - the
knowledge should apply for the most part to anyone making clocks.
I know we have quite a few of us who like clocks and timepieces, so I
figured I'd share.
