An excellent video. A friend of mine and I are involved in maintaining the tower clock at our local courthouse. We have learned much about the workings of clocks since then. The clock was made in 1908 and restored in 2010. We took over the regular maintenance at that time. We take it as a challenge to keep it as accurate as we can. When we started taking care of it we had trouble getting it to keep the time as close as we wanted. We were getting it to within one minute per month and thought we should get it closer than that. The gentleman that restored the clock chuckled and said the clock was only guaranteed to be accurate within 3 minutes per month when it was brand new! Our goal is to keep it to within 30 seconds per month and more often than not keep it within that range. The main variable in this is the temperature. The clock is not in a climate controlled area so as the temperature varies the pendulum grows or shrinks in length which varies the time. We try to anticipate temperature swings and have done a decent job of doing so. My friend and I both like old iron and this is an entirely different challenge for us and we very much enjoy it.
The same principles involved in the running of the tower clock are apparent in the much smaller mechanical watch. The video was well worth watching. Thanks for posting. Mike

But no matter how good or bad auctions may be, we always seem to stay until the item we've come for or are interested in is on the block. I've been to some auctions near and far. I think the furthest has been the Two Cylinder 7 in the Amana Colonies last year. Lots of stuff, lots of people. I've also atten
