The user winding tools for the Astro-skeleton clock were made from Mammoth ivory, maybe just a little more acceptable in your judgmental view. There is nothing like the feel of ivory in your hand. Glad you missed the other three large cabinets I have with ivory carvings, don't want to upset you too much. If it makes you feel better, I have ceased collecting ivory twenty years ago.

The clock was built in Australia and was commissioned by me in the USA. This is now where the clock is located.

Yes the moons for Jupiter and Saturn are accurate. Also all the planets with elliptical orbits are accurate and have dials in French silver that show their aphelion and perihelion in millions of kilometers, mks and astronomical units, AU. Of course Saturn has its accurate tilt from the ecliptic, but also the planets of Mars and Jupiter have their minor tilts accurately depicted. The main dial is hand painted Chinese enamel with kiln firings for each color. The bezel in gold plate. You can follow the entire project here: www.my-time-machines.net/astro_index.htm and the page where the video was is here: www.my-time-machines.net/astro_07-19a.htm. Check out the demo video here: www.my-time-machines.net/astro_07-19.htm. Keep working at it, you are young and can achieve this and more if you are willing to get there.

@@MarkFrankclocks Mark, I was going through your website, and I have to ask... is that seriously a giant elephant tusk that is on your coffee table?? 😢

I know of Martin Molin's Marble Machine and he has communicated to me on my creation. His machine is very popular partially because he has to physically interact with it to play the machine. It is visually and mechanically complex. The visuals are more eye catching as flying marbles are not something one often sees, and, of course, there's the music! This machine, (I will try to be as unbiased as I can), has a different level of refinement as the parts are small and numerous at 8000. It is also all done in metal which is a more difficult material to work with. The finish is high quality with a mixture of gold and silver plate. It also took a lot of research into astronomy and its implications to translate 71 astronomical functions into mechanical representations. A lot of the machine was first created in mock ups made of plastic to test concepts before metal was cut. It took 12 years to build plus design time.

There are many examples of complex clocks beginning in the 14th century. Their work is superb and decoratively unmatched even by today's standards. It simply took the builders a lot longer to make unless they created a consortium (which was almost always the case). One man rarely has all the skills needed to build a monumental machine. Another wonderful machine, not a clock, but the fastest calculator in the 17th century by Muriel in 1859, do give it a look. In chronological order, noteworthy clocks are: Giovanni Dondi, Italy, 1365-1381, 16 years, one man, skeleton Eberhard Baldewein, Germany, 1563-68, 6 years, several people Phillip Mathias Hahn, Germany, 1739-1790 Johann Georg Nestfell, Germany, 1757-1763. 6 years, skeleton Marie Antoinette clock, Abraham Louis Breguet, 1783, 44 years, Musée d'Orsay in Paris Antide Janvier, France, Chef d’ Overe, 1789-1801, consortium, 12 years Paul Pouvillon, Nogent-sur-oise, France, 1918-1939, 21 years, one man, skeleton Daniel Vachery, France, 1938-1967, 29 years, one man, partial skeleton Rasmus Sørnes Clock, Norway, 1946-1966, over 20 years, one man, skeleton Jens Olsen, Denmark, designed over 50 years, built 1944-1955, 11 years, by consortium of 10 people, skeleton Hans Lang, Germany, 1986, one man Türler, Switzerland, 1986-1995. 9 years, commissioned by Franz Türler, designed by Dr. Ludwig Oechslin; built by; Jörg Spöring, skeleton. The clock stands 2.2 meters or just over 7 feet in height. It contains 1.2 tons of brass and 251 wheels on 155 pinions. Astronomical Skeleton Clock, 2003-2021, actual build time 12 years, one man and commissioner (me).

It has a brass trimmed case.

Me too.

Well, it'd have to be a pretty big dog as the clock weights a bit over 300 lbs.

I do not see that style in the catalog, 6242. Is this an old one or a modern one? A photo will help. You can find my email on my website.

No blog or forum, but there is a website dedicated to the entire project from its first inception in 2003 through its delivery to me in July 2022. This link is to a month by month info on the construction with thousands of photos and videos, the index is here: www.my-time-machines.net/astro_index.htm . It has been published in several horological magazines here: www.my-time-machines.net/papers_and_presentations.htm .

@@MarkFrankclocks An "event log on the web", also known as "weblog", is the full name of "blog". :-)

Sadly, no there is nothing like this for those who cannot pay millions. This took two years to design, and a master horologist 12 years full time to make. The math demands this.

Ahh. That's a great question. Our original design had the seconds hand jump every two seconds in the same manner as the pendulums that are two seconds. A direct connection. Unfortunately for reasons that are too complex to describe here, there were instabilities introduced which caused the seconds hand to act erratically; to sometimes "skate" running 3 seconds on a beat rather than two. Sometimes jam up. So we introduced what we call a 'reverse coup perdu' escapement. In a coup perdu escapement a 1/2 seconds pendulum is converted to a one second readout. Here we convert a two second escapement to one. I believe it is a unique invention we developed. You can see it here: www.my-time-machines.net/astro_04-21.htm and here: www.my-time-machines.net/astro_05-21.htm . I'm rather proud of this invention and it makes the seconds output look like a chronometer, but we retain all the advantages of a slower moving escapement in terms of wear and duration.

@@MarkFrankclocks how.. just how can I single man come up with such genius ways to solve problems. that is incredible thank you for replying and explaining it.

Thanks. The machine is like an onion, there are many layers to peel away and surprises waiting under each layer. For example, how do we obtain the reciprocal motion of a pair of compound pendulums that each weigh in at about 15 lbs. and which is virtually frictionless and requires no oil? One give away, it is not ball bearings, they do not work well in cases of reciprocal motion.

Can you send me a link? Thanks!

@@MarkFrankclocks Of course ua-cam.com/video/oiKEpRE0SeM/v-deo.htmlsi=XR7KZYCXB3l-ICAe But it's in Spanish 😅

Greater than $2 million

I’ll happily sell my kidney and house for that
