I used to work with cultural heritage conservation, especially historical industrial sites. Your work is the best example I have ever seen of the beauty in the understanding and connection to the human past that can be found when one delves deeply into the practical functionality of old and ancient inventions. This is just like Sagan's description of books as a means of instantly entering the mind of someone else, possibly long dead and gone - only this way is so much more intimate. Fantastic work, Chris.

Give the ancient craftsmen credit, they did have a lot of time on their hands. "Noo dey harnesd da powa of audio an levitatet giant bloks o ston."

The Antikythera Mechanism has awestruck me for years and now in a single night Ive found and watched your entire series and become a better person from the knowledge and connections to the past youve established with all your hard work on the remaking and recording/editing of this device and its creation process. You are doing an incredible job and I cant wait for the privilege to see you complete your journey with all of us viewers alongside. The exceptional quality of your craftsmanship, videos, character, and attention to detail are an immeasurable benefit and joy to the world. I cant help but think as you replicate this astounding device that the sounds of your busy workshop ring back through the ages thousands of years and forge a stronger relationship to our ancestors that is exceptionally rare to find/create/understand. To think, many of the things you have done are near identical processes and a direct link to all our humanity and that we are all fortunate enough to experience it with you. I can only imagine the direct connection you feel to a time long before us. Thank you, and best of luck to you on your endeavors and life overall, as well as all those you share your life with, I know mine has been vastly enriched by you at great convenience and when I go back to work (Industrial Maintenance) once my broken ankle heals I will donate to this wonderful channel. P.S. So youve almost finished this project it seems, might I suggest my idea for the new one? Another mysterious feat of human engineering, The Great Pyramids!! All joking aside I do wish we knew some of the mysteries that still surround the structure today, but one amazing achievement of mankind at a time I suppose! Time to watch your Byzantine Calendar videos and hope for the publishing of what Im sure is a phenomenal paper youve been rightfully brought in to help on.

It's not just the making of mechanism that i like in your videos, it's the making of tools. I make stuff from time to time, and even if it's for just one piece, making a tool really helps.

I was so fascinated by the Antikythera mechanism I read everything I could find on it. I also like the demonstrations of tool making. I’ve watched your videos over and over again. Bravo, bravo! P.S. If you would like something a bit different, violin making is steeped in history. I know a couple very well established makers who are pretty good at problem solving. Your tool designing and making would fit right in.

[@priitmolder6475]

As always, a joy to see a Clickspring "spares" video. To be honest, the Antikythera mechanism is not as interesting as the research to tools and techniques. There are few of us who are interested in a "stellar computer" and even less of those who can use it efectively. But to see these simple tools in action is the TRUE knowlodge that should be preserved. For the home-shop, shed and armchair machinists out there.

[@NGC1433]

That stellar computer predates all existing civilizations. This computer and ways it was created is of utmost importance and methods cannot just be separated from the context, the device itself. How mind numb do you have to be to not realize that? European people discovered that shitting where they live is bad like 2000 years later! it is at least 2200 years old, and we were burning people for implying the earth is not in the center of the universe 500 years ago. Do you really want this to be numbed down to "you can take a sharp piece of steel to a bronze and scrape a slot in it" ???

[@satibel]

@@NGC1433 those are social, not engineering changes, though it puts it in context. we have computers doing almost all of our stuff and we still go at war and run in the wall with our bad industry practices. and imo the tools are also the interesting part, with just the calendar you could do some great stuff, but with the tools and some ingenuity, you can build a lot more.

[@priitmolder6475]

@@NGC1433 Im not dumbing down anything. Everything has its function and place. But in the CONTEXT of Clicksping, the methods and tools outweigh the actual item. Do not forget: there is a reason why design, analysis, tooling and craftsmenship are all SEPARATE disciplines! We have an Anthykera mechanism, but we dont know HOW it was made. Chris gives us an invaluable insight to very simple, yet effective methods. I bet you would find use of some simple tooling method rather than a "stellar computer"

Very interesting! First we have the approximation of a spiral by offset-centered half-circles. Then we have the humble trammel with a cutting tool instead of a point.

This is incredible. Detail, thought, precision, skill, execution, insight and my god the patience.

[@terrygingell7253]

Most people would have assumed that such a complex shape would have required a complex tool. I would have. Of all the impressive aspects of this video I found the consistency with which you kept the start and stop points for the arcs tangent, for want of a better word, to be the most amazing. The trammel blocked you view of the intersection and I didn't see you using a stop of any kind to limit the swing of the arc so how did you do that? What did I miss? Modern machining is all about speed but that must have taken hours and hours to produce those cuts, chewing through what I'm guessing was a 4 or 5 millimeter thick plate for God knows how many inches of cut. Your patience is legendary! Splendid work as always!

[@SianaGearz]

I think it's pretty easy to stop when the tool is parallel with the edge of the plate, similar to filing technique where you align your files with surrounding geometry, except you don't have to pay attention nearly as much. Another great possibility is to have two centre buttons both as wide as the tool, and you stop when the tool aligns with the other centre button. Finally, a small over-run at the stopping point is not very critical since ultimately the curves coming up from top and bottom match up pretty closely, in spite of not being a true spiral. Another thing is that you can always verify your start point visually by peeking below and having a layout line there, though this doesn't work that well for a stopping point as it will be obscured by the chips.

[@kriss1_]

@@SianaGearz Or just a viewing hole at the end of the 'stick' with a centered notch to line up with the scribed centerline on the work piece.

[@Mister_Brown]

really once you start each groove it's almost impossible to overshoot the endpoint since it would take considerably more force to move the depth of cut required, especially given that the tool has no provision for cutting on it's sides only on the bottom

Great video as always! I'm no expert in ancient Greek pottery, but assuming something similar to a modern pottery wheel was available, I could see that technology being combined with the trammel presented here.

[@jasondoe2596]

Good point! Yes, their pottery was quite advanced, I'm sure they had pottery wheels. (And Wikipedia suggests their use was already widespread in Middle-Eastern civilizations since much earlier.)

[@bwyseymail]

Yes, I can see that it would be much easier to turn the work with your feet while holding the trammel in a fixed position.

You clearly have no idea how important a ball bearing is for a lathe precision and how it revolutionized everything. And ancient greeks did not have ball bearings. you cannot just magically "combine" things. Read up (or watch youtube) on precision and it's history.

@@NGC1433 Jon and Moon are correct. The old No. 2 Cincinnati milling machines, made from the 40's to as late as the 70's used (tapered) bronze bearings in their universal head attachment/variant. Lovely accurate machines, no problem.

Initially misread that as treadle, and thought you'd be building a simple lathe driven by the operator's feet. While I'm disappointed not to see that, this was perhaps even more fascinating! It would have never of occurred to me to do it like this.
