Abbreviated Transcript:
00:40 The Greek civilisation was well into the Iron Age at the time of the devices creation. But the question of steel availability is not easily answered. Certainly there was a form of crucible steel known as Wootz, from the region we now call India. But there was also the technique known as case hardening, which essentially converts the surface of an iron object into steel.
01:23 The first step is to take this raw stock, and shape the basic file blanks. In recent history, this job was done on a massive grinding wheel. And although it would of course have been much slower and less convenient, similar hand powered abrasive tools are known to have existed in antiquity.
02:46 No matter how much I roll the file on top of the work, it rotates so that the file will still cut reasonably flat. Ok, so with the file surfaces stripped, the next step is to form the teeth. And I need to make a few more custom tools to get this part of the job done. I've made a simple file cutting workstation, based on the traditional approach, but scaled down to suit the size of my shop.
06:15 And that first tooth now becomes the reference for the next tooth. The chisel blade is slid up against it, and then the subsequent teeth are laid down one after another. Each time, using the previous cut to locate the next.
08:59 Well I'm not about to give up my commercially made files any time soon. But they do work quite well. They're probably equivalent to a modern #2 cut file, and although the cutting action is not quite as sweet as a new, modern file, its a reasonable balance between metal removal and surface finish. They're durable, easy to handle, and certainly perform well enough to have constructed the original mechanism.
10:31 But there's still quite a high degree of consistency of the root angles around each given wheel. That suggests to me that the teeth were in fact formed by simply plunging the file into the workpiece, like I've done here. And that the root angle variation observed across the gearing, was in fact generated by a small selection of files cut specifically to construct this mechanism. Ok, so to wrap this one up, Its still very early days for this reconstruction. And I've still got a lot more research to do into the tool technology behind this machine.

[@AlRoderick]

This is great, almost every discussion of old tool technology I've ever seen stops at knapping flint and picks up at the middle ages, skipping millennia of slow, steady advancement. Thanks for doing your part Chris.

Chris' attention to detail and dedication to making this project as historically accurate as possible make these videos an absolute treat to watch. It is not often that one can get such an in-depth glimpse of ancient history, and these videos deserve way more views for doing just that. Keep up the awesome work!

[@Clickspring]

Cheers Jack, appreciate your support mate!

[@jimandaubz]

Interestingly, the lack of uniformity in hand made files, is shared in high quality machine made files, because if the tooth spacing is too uniform the file chatters, and fails to make a good cut, and instead squeals and digs in from vibrations generated at a high frequency. Nicklson (did I spell that right?) file corporation invented the first file cutting machine that was suitably Random to mimic hand struck files, and allowed for machine made files to take over. Betcha if ya used a nice hard modern tool steel, it would end up better then most store bought files! (That are made of straight high carbon steel still... some tools refuse to evolve) I like watching files get struck, there is some magic in the process, happy to see your channel. You earned a subscriber.

[@daw162]

Not sure what you mean by a modern tool steel, but there isn't much of anything that will make a better file than a mildly alloyed 1.2% carbon steel. Steel that's more highly alloyed has problems other than wear resistance, especially in fine edges (like tips of file teeth) under any pressure. The cobalt steels are about the only thing that gets a little harder than file steel (file steel can come out of the quench at 68), but cobalt steels are extremely low toughness and the teeth would break right off filing steel.

[@mikebergman1817]

[@davidkohler7454]

I have watched this entire series more than once or twice,. I love how Chris starts out by making the tools necessary to complete the project.to show how it was actually done ions ago..to reverse engineer everything after seeing the end result still has to be easier than designing and building it the first time,with nothing to compare it to. It is all just so amazing to me. Love this channel.

[@PCanas]

Am I the only one here who can't stop thinking about the paradox of needing a file to make a file?

[@doubledarefan]

A flat piece of granite could have been used.

[@tyttuut]

*mind explodes*

[@cmdrsocks]

If you did not have a file, you would start by making a scraper to flatten your blanks. The scraper is essentially a toothless file blank with sharp polished corners. It can be made using just abrasive stones to flatten and polish the edges.

[@robmckennie4203]

I would assume you could get away without filing the blank the first time, then use those poorer quality files to improve the next set you make.

[@felixar90]

I guess it wouldn’t really matter if the first file wasn’t perfectly flat. It would still be enough to make the next file a bit flatter. Then you can make progressively better files

[@nikolovell]

I really admire that you don't take the easy way out, but instead use the techniques and methods of the original makers of the tools you're constructing. The fact that you do your work not completely for the end product, but mostly for the experience is also respectable. Your hard work is a huge inspiration!

I am staggered by the step change in technology that these relatively simple tools would facilitate. Its amazing to see them made from such humble beginnings. I'm hooked on the series now. No question!

[@ohgary]

Roy Underhill had a show where he went into the woods, found a lump of iron ore and some coal and turned them into a woodworking tool that might have dated to the early 1700s. Just finding raw material in nature seems almost insurmountable yet here you are. And we know the ancients did it. Darn shame iron tools deteriorate so rapidly when buried. Your video explains much.

[@Cancun771]

Loving it. The first file I bought was a #2, simply because I was clueless and there were three grades to choose from, so I thought I couldn't go too wrong with it, staying in the 'middle of the road'. When I showed that to my friend the apprentice metalworker, he was surprised and said usually nobody went with the #2 but all the shop workers used a set of #3 for rough shaping and #3 for finishing the filing job. Served me well all those years though. I can see the master craftsman in his rough chiton have apprentices hew files for the shop and carry out all sorts of endless repetitive tasks, weeding out the wheat from the chaff according to the quality of their workmanship afterwards.

[@tcl379]

It goes without saying but I’ll say it anyway. Your presentation was accomplished without the glaring and telling need for recognition and significance typically found on KZbin. It is refreshing to witness what was possible and subsequently accomplished in ancient times by people who saw possibility and then invented the technology and tools needed to make it happen. Your presentation clearly demonstrates the human capacity for creativity and inventiveness. Thank you.

[@raymondyee3313]

A huge tip of my hat to you sir from an old T&D maker.

[@BFDT-4]

My grandfather was a "tool and die maker". I don't know where he got his training, but he came over from Weimar Germany to the US (Chicago) in 1923-24. He worked for years for Western Electric. He made various things out of brass and steel. Don't know whether he made any tools at home, but we had some various tools that seemed hand worked. These videos about the Antikythera Mechanism (AM) are so amazing. Both because of the memories of his workshop and because of the incredible craft and skill the Greeks used and then subsequent people/cultures LOST until very much later. I wonder what the guy thought who was going to receive the mechanism at the arrival port, only to be told that the ship sank. Was the AM a one-off, or did he order another with the insurance money? ;)

[@BFDT-4]

A follow up question. How close are we to creating a restored workshop where the AM was made? And from that, what could be said about establishing the technology level of the maker and his/her guild mates? And then, how could we develop a tech manual that describes/preserves the ancient workshop/culture? I am in awe of what we had and what we lost.

I'm blown away once again. You stay busy don't you. I loved the clock, but this blows it away. 1.) I think it's amazing that you are making your own tools and doing much of it with the known technology. 2.) You are doing real science, and probably a lot better than a team of researchers studying old papers, and the original mechanism and whatnot. I believe quite a few doctorate theses could be written off this project. 3.) You will probably have the most accurate recreation in the world. There is few better ways to figure out how and why something is than to do it yourself. Great work and please keep it up.

[@moldering]

When I worked at Cartier New York in the jewelry work shop ( mid 1970s)one of the older jewelers who had worked during WWII told how during the war, hand files were in short supply, and when the old ones were dull, they would put them in the hot sulphuric acid pickle thus dissolving enough steel to "sharpen" them , that also killed the pickle for jewelry work. I enjoy your videos very much thanks!

Hi Chris, When I started my apprenticeship in the electrical/radio trade with BHP at Newcastle NSW the first 3 months entailed basic fitting with BHP and one day a week at TAFE with electrical fundamentals. At 15 in 1965 I had no idea files had been around for over 2000 years when I was first taught how to use them properly and file within 2/1000" 2 thou or back then it was 2 mil tolerance. I am finding all your video's fascinating along with quite a few other people. I turn miniature parts up on a mini lathe to replace mechanical parts on reel to reel tape decks as you can probably guess these are no longer manufactured. The skills I learnt so many years ago are still there, a bit rusty but still there. I manly work in brass, bronze or copper so your videos on the Antikythera Mechanism I find is so interesting to me, I have learned quite a few things. It's amazing you are working without detailed drawings, only from x-rays of a device left on the sea bed so many centuries ago and piecing together what techniques must have been used .......Regards Robert.

[@TrueSighted]

Oh, and P.S. Quick tip for cleaning your files when they are all full of left over material. Just take a piece of copper, about 3 inches or so long, and with a little bit of girth to hang on to. As well as a flat edge. Take and put it against the edge of the file, aiming to move it along from one side, to the other, going with the direction of the teeth groves. Press against the files surface firmly, and as you do, the teeth of the file will indent within the copper, filling all the voids of the file along with it. As you go along the grooves, it will remove any old material. Just repeat until you reach the end of the files face. This will make an old file as good as new and is great for cleaning and upkeeping files to keep them in good condition. It comes in handy.

[@carloshernandez2561]

Just want to add, you can also add chalk to your file to keep it from loading up

[@TrueSighted]

@@carloshernandez2561 good addition. 😉 I rarely use it when working with precious metals, due to wanting to reclaim any scraps and filings without contamination; but no doubt it will work.

[@MacheteBushcraftAustralia]

As always, classy work mate! Thank you for sharing the info. I stumbled across an article years ago about a European company wanting to automate the hand cut file making process. The first problem they faced was that the machines cut perfectly spaced teeth and the files would not cut properly. They needed to create some tiny variations in the tooth spacing across it's length to mimic hand cut inaccuracies. .... I'm off to measure some files now that I remembered that.

[@nilwon]

Long time lurker here. There isn't a single video you've put up that I haven't liked, but this one in particular may be my new favorite. At 11:02 You started to put the tools of the ancient workshop together, side to side on the table, and I got shivers. I'm no metalsmith, but I'm intensely interested in the evolution and development of tools: the ingenuity behind each one, the highly specialized knowledge and ideas which helped to propel human curiosity and technology forward. Your step by step demonstrations of how the sophisticated tools necessary to build the Antikythera Mechanism could have been made is equal parts comprehensive, fun, and beautiful to watch. This is great stuff. Thank you for sharing your fascination and expertise.

[@Afro408]

Great and informative video, as usual Chris and as an old toolmaker and retired Gunsmith, I have gone through lots and lots of files in my time. Your work is superlative and always interesting to watch. A suggestion for the file making chisels, if you don't mind. Shape the struck face of the chisel, so that it comes to a blunt point and this will negate the sideways kicking of the chisel, if you strike it off centre with the hammer. I noticed this happen quite a few times during the process. You will also get better energy transfer. It was interesting to see yet another method of case hardening and I am going to give it a try, as it seemed like a very positive method. I have always told my trainees, that there are no real shortcuts and time spent in making good tools, is reflected in the quality of the work they produce. Cheers, Tony

I am so impressed to see this video. I can never find the type of files I would like to have. For example, files of regular shapes, triangular, flat, round, etc, but, smooth on one or more sides, with the filing surface only on the other, which would allow me to file, using the smooth surface(s) against a guide or the work piece itself, only filing stock on the filing side of the file. And, the coarseness of files, is just never right.

Three videos! This is the best Christmas ever. It's not Christmas? Well, this is so much better!

[@Bidenrocks13]

Well done the time spent is appreciated by a lot of us. Keep up the great work.

[@ScrapwoodCity]

Awesome

[@DarkDays4]

"What did you do today? Oh nothing just made some files by hand, then used them to make a gear. You know the usual."

[@emomikey38]

i cant get over this, this is simply AMAZING! SO inspirational

[@BAK87]

Making the files totally blew me away. Impressive crafting!!

[@YooProjects]

WOW.. AMAZING WORKS!.. THX I ALREADY SUBSCRIBER IN YOUR CHANNEL.

[@vinh7251]

I recently stumbled across this channel via ToT and frankly it blows my mind, everything you make is just beautiful mate. One quick question - why charcoal made from leather instead of the cheaper and more readily available wood variety for the case hardening? Informative content and superbly presented, keep up the amazing work!

[@robertqueberg4612]

That is a logical question for a subject like carburizing or case hardening. I can not provide an answer, but for another facet to pursue is “color case hardening”, which has been used on many “best grade” British shotguns and machinist tools like parallel clamps. It seems that each manufacturer had their own recipe for mixing bone and leather to produce the beautiful colors that were their own. Take care.

Excellent work clickspring,always interesting.

[@markpaas]

Chris you're the best. Period! I always love watching your videos.

I was about to go get some sleep. Sleep can wait! :D

[@JavierBonillaC]

I thought the teeth would had been made under heat. I never cease to be amazed! Excellent video. Congratulations.

[@toastinat0r]

Simply the best videos. I hope you never stop. Super high quality

[@1337fraggzb00N]

Reminds me of the German TV-Series "Der Letzte seines Standes?" ("The last one if his kind?"). There was an Episode of a Feilenhauer (file cutter) who used the old technique to maintain worn files and build new ones that are superior to machined files. He intentionally makes the cut asymmetric to reduce visible markings on the work piece later. The series has 68 episodes and each one shows very old, rare or even extinct ways of tool making and machining. kzbin.info/www/bejne/oaC9nH56dsxmkNU

[@kookyflukes9749]

Hi Chris. I noticed that you flattened the files using a file. What did the ancients use for this step?

[@Clickspring]

Hello mate - An abrasive stone would have been effective enough to dress the blank begin with, and then once the filemaking tradition was more established, they would have used files as per the video. The standard and fineness of the file cut (and therefore the subsequent blank it could be used to prepare) would have rapidly improved with each successive iteration of the process. - Cheers :)

[@shonaoneill5151]

Clickspring Agreed, abrasives were as common place then as they are today,.....kind of. Pumice stones have been used for thousands of years as a simple abrasive, simple rocks for refining the earliest of tools. Admittedly it would have taken a long time. But, they had plenty of it I suppose. The engineers in charge of this whole operation would have had 100s of minions to help he/she is the making of the instrumentation, of that you can have no doubt. This series Chris, is as fascinating as it spectacular. I enjoy watching someone who is so passionate about precision as I am in my shop. I'm afraid the modern expression "close enough" is just not in my vocabulary. But, I don't have the time to make up all the tools from scratch I am sorry to say. You are an inspiration Chris, I would love for this to be shown in schools around the world. Just to show, that quicker is not necessarily better. Best wishes to you from the UK. Pete

[@Sjackson2369]

I read this in your voice lol so cool. But as someone who dabbles in blacksmithing i found this video INCREDIBLY informational and helpful. I may have to make my own.

[@maxscott3349]

Shona O'Neill Who uses pumice as an abrasive? Was there no flint in all of Greece?

[@km5405]

its amazing what you can do with just basic materials and technology.

[@SonnetGomes]

This is amazing how it is made. Thank you so much for sharing these videos.

[@johnkelley9877]

Fascinating! I have always been interested in how files were made and you have answered those questions. Thanks for sharing this and I cannot wait until the next video.

[@MoSeedat98]

I clicked on this so fast

[@LoudTechRyan]

Mohammed Seedat same

[@robr3015]

Same here. I love Clickspring's videos, and master craftsmanship.

[@Pan_Galactic_Gargle_Blaster]

You could say I sprung to click it.

[@jimstamper7062]

I let out a little WOOT! when I saw their was another clickspring vid

[@PurpleHaze2k9]

Noooooo shit! Such good wholesome material. I only wish I could donate.

[@legotechniccreations6630]

What type of clay do you use for this method? Is it just over baking modeling clay from the store or is it a nicer kiln firing clay like stoneware clay? Great video, keep up the amazing work!

[@Clickspring]

I used this clay: shop.walkerceramics.com.au/AA21/Feeneys-White-Stoneware-~10kg-NEW/pd.php

[@legotechniccreations6630]

Clickspring thanks a lot!

Phenomenal patience. I always wondered how files were made.

[@dickJohnsonpeter]

It's amazing what you can create with enough patience.

[@Enjera_Hlm]

I knew they used files, but I didn't understand how they made files themselves.

[@asid61]

Only you would have the patience to hand-punch all of the teeth on a file.

[@aspartns]

Or ten of them

[@1pcfred]

Actually as he alludes in the video, this is how it was done. So back in the day everyone had the patience.

[@1theheightofparadise]

we're all just lazy these days lol

[@KaseyWynne]

Or nothing better to do :) If you don't have a tv to go home and watch you might be more willing to stay and work.

[@1pcfred]

TVs don't make you turn them on. There's really nothing on them worth watching anyways.

[@merlinchampenois6754]

A superb video, the way you make those files is very interesting. Watching you from France

[@Mister_H.]

In this day and CNC age I sometimes get a little disillusioned doing the work I do but watching your videos reminds me why I got into it in the first place. Thank you for that 👍🏻
