Half Way Point For The Astronomical Skeleton Clock
Below are some complicated horological examples through history. Not all are skeleton clocks. All however contain a large number of celestial functions and most do have some or all exposed wheel work. One half are from the twentieth century since I wanted to have some closer comparison in style and manufacturing technique that was closer in time to this project. While the total time that I have into this project will be close to ten years, the development and construction time that Buchanan has will be about seven to eight years, pretty much in line with the examples below.
Medieval astronomical table clock by Eberhard Baldewein, Vienna, Austria 1563-1568. 5 years.
Institutional sized orrery with clock by Johann Georg Nestfell, Germany, 1757-1763. 6 years.
