Enother interesting information: specially for you.

- What do you think about this? see, and tell us now.
- Yes, the chronometer is powered by a chain fusee. It amazes me how many skeleton clocks I've seen and in my collection that are unsigned. It seems that this practice is more common on skeleton type clocks than other types of clocks. Why this is so I cannot explain. You can see more of this clock on my website.
- The way the moon's rotation and inclination as demonstrated in this orrery is only approximate. This is the case for nearly all astronomical models since the actual modeling of the moon's complex motion is very difficult. However, it has been done, basically through modeling the motion through cam-works. See the Schwilgue cathedral clock in Strasburg, The Jens Olsen clock, Denmark and Rasmus Sornes (private collection) among several others who have used the cam-work method for this complication.
- "This is the case for nearly all astronomical models" you know, i kinda thought that might be the case! i'm still pretty uncertain about a lot of the aspects of the craft; i tend to overthink things, which ends up giving me a complex! thanks for the informative responses. you're always too gracious.

- what a stunning piece, and to go unsigned. what the hell, i'll take crdit for the design! is that a fusee at 1:18? KEvron
- i've thought of trying my hand at an orrery, but the medium in which i work is limited in its selection of gears. the best i would be able manage, via direct gearing, would be a 1:28 ration (3:82 would work better, but that's not available to me). how do makers create the proper ratio, given the moon's irregular rate?
