Abbreviated Transcript:
01:19 Now before I do any more with this wheel, I'd like to show you a bit more detail on where it fits into the mechanism. Its permanently fastened to the main Solar Drive Wheel B1, and its part of the gearing associated with the back half of the device. In fact its the first wheel in that large and quite complex part of the mechanism.
01:37 It engages 2 wheels, that in turn drive the gearing that animates the eclipse prediction display, the calendar display and the lunar phase display. Now that's a lot gears, generating a lot friction. So the load on B2 and its rivets is considerable.
02:04 And secondly, the scans show 4 quite substantial rivets placed in a symmetrical pattern around the spokes, that hold B2 firmly in place. Its a very neat solution that wouldn't be out of place in a modern clock mechanism. Now the central bore of B2 needs to be opened up to match the main bearing and it could be simply drilled out on a drill press.
02:51 And you'll notice that I haven't used any marking fluid to make that circle more visible. I've done this to show just how hard it can be to see even a simple object line on bare metal. Even up close I think you'll agree it's not exactly the clearest line you could hope for.
03:49 One to locate parts on the division plate, and one to bring all 3 components into alignment for drilling out the rivet hole positions. Now it certainly doesn't meet the requirement of robust handling, but a very straight forward marking material worth investigating is candle soot.
05:02 The positions for the 4 holes are now firmly located over the centerline of each of the spokes, and can now be drilled out in preparation for accepting the rivets. And as tempting as it is to just drop in all 4 holes at once, even the slightest movement of the work whilst drilling can lead to an unacceptable misalignment of the holes.
05:44 The 4 rivets were turned to size, and left just long enough to allow them to be comfortably held for insertion. By now of course a lot of the soot has worn off, so I think its clear that it really wouldn't be suitable for marking out anything that needs a lot of handling, like for example the wheels.
06:57 And then started the process of permanently setting them in place. I made sure that each rivet end was thoroughly peened, and that the metal was pushed well out into the chamfer, giving not just a seamless join, but also good solid mechanical strength. And for the final step, I used a file and 800 grit abrasive paper to blend the rivets into the surrounding metal.
08:23 And as I reach the end of this video, its hard to escape the thought that over 2000 years ago, there was moment, just like this.

[@Clickspring]

Hey Folks, In this video the most recognizable component of the mechanism continues to take shape, and becomes the first moving part within the plates. Please enjoy! Chris.

[@TheJttv]

Clickspring I just want to say thank you for the hours of entertainment and machining lessons.

[@Proxima256]

Thank you Chris, inspiring and interesting as always

[@alexkepa12]

Hey, Chris, I have a random question that really doesn't pertain to the video exactly, but would it be possible to cut curved or slanted gears (like those found in car transmissions or at the end of a distributor) I wanted to try and make some drag race parts for a mini bike/go-kart, and would like to try and make some out of good quality steel or aluminum. Thanks a bunch,Alex Paschke

[@gordonlawrence3537]

@Alexander Paschke I would guess you could do it in mild steel if you knew what you were doing. The problem is that you need something harder at least on the surface so it does not wear ridiculously fast.

[@ExtantFrodo2]

That it doesn't clean off easily is a plus for candle soot.

[@dil6969]

This channel is one of KZbin's best kept secrets. Among all the click bait and low effort vlogs, there are many hidden gems if you're willing to look for them. I can thank AvE for promoting wonderful craftsmen like yourself.

[@Clickspring]

Great to have you watching mate :)

[@originalusernamefail]

I would actually loose my shit if chris chucked in AvE's sign off line "keep yer dick in a vice" in his next vajayo...

[@cricketshine1160]

originalusernamefail that would be amazing!

[@ThomasHaxley]

@@originalusernamefail that would be so good!

[@joshrepik]

I didn’t know AvE mentioned clickspring, that’s awesome. I stumbled upon antykthera fragments all on my own and was hooked

[@masheroz]

I find it amazing the way the rivets disappear one you've sanded them back.

[@hommebizzare]

Matthew Rowles He also does a VERY thorough job of the peening process :) I would probably just have wacked it with a hammer straight to the pin :)

[@MaxMakerChannel]

Matthew Rowles I would love to see just a single of his sanding and filing operations in real time. Just to get a sense of the time it takes him.

[@RichardHeadGaming]

Me too seeing how that did the job for thousands of years including the original he is copying.

[@markdammes1947]

How is the clamping strength not lost when the peened over end disappears?

[@MaxMakerChannel]

The peened over metal actually digs into the surrounding metal and interlocks.

[@sheps5656]

Ground up charcoal in wax. A thin brushed on layer would be easy to mark, resistant to handling and give the same black contrast.

[@danrasmussen4125]

Sheps I was thinking same thing

[@joesouthwell4080]

Also, if the wax was placed on top of the gear and then the gear was heated, the wax could melt and naturally pool level (no need for a brush). It would also create a surface that would be simi adhesive to help pieces stick together for alignment/placement.

[@Clickspring]

Will check it out, thanks for suggesting :)

[@tomasjonsson3064]

Why not just use squid ink?

[@frankhatton8242]

excellent what more could I say! !!!

[@Brian-cw9pp]

I'm a jeweler, and while I was an apprentice I was taught to use asphaltum varnish for a coating that can be scribed into for marking. I don't know if it would be historically accurate, though, but I know the main ingredient, bitumen or pitch, was used for other things. I'm not sure what sorts of solvents and things would have been available.

[@gryyphyn8639]

I had the thought of using Dyer's Woad and cedar sap. Woad was used as a blue dye in fabrics and, while expensive as a dye, it had a brilliant blue color and was pretty available as a component of fabric manufacturing. It's still used today in some applications. The cedar sap would have been readily available by boiling cedar and reducing it to a simple syrup that would harden when heated and should form a film that, when tinted with woad, should be similar in color to Dykem and should be fairly chip resistant if applied thin enough.

[@ArmchairDeity]

Hellsong89 as a pure water based substance no... but dried and mixed into a wax or lacquer? Sure.

[@bjorncarlsson6295]

If one mix soot with grease, it might stick a bit longer. This mixture was also used as eyeliner in ancient Egypt, so the compound was contemporary with the Antikythera an probably both used in Greece and well known to the makers.

[@BobbyDukeArts]

Dude, watching you work gives me goosebumps (the good kind). Your channel is my ASMR

[@michaeldow7167]

Couldn't agree more. Just watching Chris work is an inspiration. When I get annoyed or fed up with a job in the workshop a dose of ClickSpring works wonders. Sheer joy to watch.

[@unvergebeneid]

Funny you should say that. I had exactly the same association. Just about everything that's happening in these videos qualifies as "oddly satisfying." It's all so neat and precise and the materials are so beautiful!

[@helloidkwhatimdoing653]

woah I just found Bobby duke from before I started watching Bobby duke

[@MrDave5906]

Kermes dye may have been used in ancient Greece back then

[@CharlesHuse]

Loving this. I'm thinking that back in the day when this device was originally made, an apprenticeship was actually quite different from what we know today. In the era around 50 BC, the student would have to go through the steps of first making their own tools and learning how to use them by completing simple projects. A the student made more complex tools, they would be taught more complex skills and create more complex projects. Something like the Antikythera machine would be akin to their final exam. I went partway through an apprenticeship program for electrician. It sucked. They were not interested in teaching anything. They only wanted to get the project done as quickly as possible so the supervisors could split that fat bonus check at the end. The joke was on them because many of the so called apprentices and helpers were so inept because no one wanted to take the time to teach proper skills, that the time budget was screwed 3 months into the project and the materials cost was over budget as well, both of which ate into the bonus. No real professionalism in the trade anymore.

[@icebluscorpion]

that's the sad truth today, pal. i can feel your disappointment. I had the same experience as well but I'm an electrician now. i got my knowledge from the books and the skills from practicing that book knowledge mostly Auto didacticaly. by making mistakes and learning from them. i was just a slave in the eyes of my electrician supervisor back then when I was apprendist to electrican. it is very sad that every one is massively driven by money this days... i would had loved to teach a apprendist the art of the electrician but sadly nowadays only a few companies teach... so i leaved the construction sites and i studied even more and now im working in the industry as electrican for electronics in the quality proofing section. what I want to say with that. be your own mentor and don't let you down if no one wants to teach you the art of some profession

[@xarin42]

There's some decent evidence that apprentices were treated that way most of the time back then too. Time hasn't changed that you need either luck or connections to get a good teacher.

[@bigchooch4434]

Every time I watch a mechanical fastener disappear into the surrounding metal I cry inside. It just became impossible to tell how those plates were fastened together because of how beautiful his craftsmanship is. That's literally the ONLY negative thing I could find after watching all of the videos on this channel is that his work is too perfect.

[@arfamortis1]

Tallow soot is oily and sticks well. Have a look at how Purdey or Holland & Holland guns are made, they use a mix of paraffin (kerosene) and oil. They use soot extensively during manufacture of their hand made guns.

[@kamakaze2007]

i assume they prob had an easier time getting tallow too

[@hazbutler]

This could be an historically important piece of engineering and construction, and the fact that you're documenting it so well is a testament to your creative abilities. Well done.

[@trevorschretlen3884]

Some basic research raises some interesting ideas about the dye. Apparently, the use of purely mineral dyes was not enormous in ancient Greece, as they preferred plant and animal based dyes. This opens up a realm of possibilities, considering the island of Kythera was known as the purple island because of the amount & quality of the purple dye produced there. I don't think purple would have been used, as it was incredibly costly and time consuming to make, however, I do believe they may have used either the kermes insect (which was also expensive, but still cheaper than purple dye) or they could have used an indigo dye made from Woad which is supposedly mildly corrosive. Now, that is assuming the color resided in the blue area of the spectrum. I think your initial exploration of the candle black was a good idea, however, I think you should try other kinds of candles. Assuming the one you used was made from paraffin, which burns cleaner than both tallow and beeswax candles. Since paraffin was not available at that time, I suggest you try finding a tallow candle and a beeswax candle and using those to see if their soot is more durable. Best of luck!

[@DeathMetalMusic-SavedMe]

G'day, loved your reply and knowledge, yes I'm 6 years late to the party as only found this by channel by accident, and as a history lover I enjoy learning new info. I do not know if this is helpful, correct or even gonna reach you. I know in Roman times, PURPLE was only allowed for the ultra wealthy/elite. It was a way to separate the classes, and PURPLE was banned to everyone except the elite. I'm not sure wether it was like that in the period you are talking of, YET I thought I might share my small amout of knowledge and PURPLE was mentioned and I was like, YAY I CAN INPUT A SMALL AMOUNT INTO THE CONVERSATION, even 6 years too late 🤫🤫🤫🤫🤫🤫🤫🤫 I hope this was useful and knowing my luck you possibly already new this, yet I thought I'd reply, just in case. Have a fantastic February 2024 From Maryborough Queensland Australia 🦜 🦘 🤠 🇦🇺 🦜 🦘 🤠 🇦🇺 & Cheers 🍻 🍻🍻🍻🍻🍻🍻🍻🍻🍻

[@doronron7323]

What a marvellous series of videos. Every step illustrated, showing tools and methods. This is what I imagine this is what 'Fitting' is about.

[@Martin-pb7ts]

I've always commented on how good your videos are and how amazing the production is but what struck me today when you were filing the gear was the level of patience you must have. I really admire the workmanship that goes into everything you do, well done.

[@themoomon1]

hey Chris names Chris Im a chemical engineering sophomore at western michigan university and I just wanted to say that your videos inspired me to walk into the machine shop of my school and ask to learn how to do metalworking. I've been a woodworker for as long as I can remember( going back to making square 2X4 cars at 4 years old) but I had never done metalworking. Your videos inspired me to learn the craft and now three weeks from walking into the college machine shop i work there. I've seen your entire clock build twice and I would love if you put out more videos (more often perhaps)to inspire young craftsmen like me. Have a great day -Chris Oh also along with working for the school i'm able to work on my own projects. My first project was a metal scribe, made from a dowel pin in a turned brass collet in a turned wood handle made of purpleheart. I got the idea from your make video.

[@Clickspring]

Terrific to hear that Chris - I wish I put out more videos too :)

[@HomeDistiller]

A wax mix with charcoal has already been suggested, but I think you are on the right track, I was wondering what would happen if you rubbed the part with wax and then hit it with the candle soot, the wax should help hold the soot, and you could also easily get a nice thin even layer, plus one candle gives you the whole layout dye kit!

[@Clickspring]

Yes definitely worth a look, cheers mate :)

[@buildmotion1426]

The level of patience and detail from your work Chris is inspiring to say the least. Thanks for another great video.

[@jesse6409]

Probably abit gross but I imagine dried animal blood would do the job of marking fluid perfectly.

[@themastermason1]

Yeah, but for non-ferrous metals only though. Blood will cause havoc on iron alloys.

[@JensAndree]

First time I accidentally got blood on a rifle the bluing disappeared very quickly where the drops were. Since then I'm very careful not to get blood on any ferrous metal. I think soot is the right path.

[@jepps77]

i just replied the same thing as you....then i saw your comment

[@sheep1ewe]

That soot coating is actually historical accurat, it´s still used by some Gunsmiths. But, still Your idea is interesting i think i will try it some day just because i am curious about how it will be to aply on the surface.

[@BestFleetAdmiral]

That's interesting, why does it do that? There's iron in blood lol. I don't usually think of blood as corrosive.

[@majord_nz]

Absolutely love this series. The attention to detail and absolute craftsmanship of Chris is something to behold (and aspire to)

[@mike-lu8di]

Home Made Spag Bog for dinner and Clickspring....Doesn't get any better for a single bloke..thumbs up :)

[@Clickspring]

Cool mate :)

[@mxcollin95]

mike just curious what is spag bog?

[@dancan4949]

mmmm Spag Bog d(^-^)b

[@AwsomeVids83]

what on earth is spag bog? I lived in Australia for a while and even so i have no idea what that is.

[@Fennecbutt]

Spaghetti bolognese...

[@gpetters]

I admire all the time you invest in getting highest quality of work, tools, video, and teaching. Excellent! Eagerly looking forward to next episode as Christmas for kids. Keep them coming!

[@Clickspring]

Will do mate, terrific to have you watching :)

[@Varashtras]

I know a lot of possibilities have already been posted but I have two more suggestions to add: 1) Milk of lime - Can be easily produced from shellfish, dries to a white coat. often used in "Whitewash" finishes. Pigs blood can be added to give a pink colour, and egg white and wheat flour can be added as a strengthener to the finish. 2) Gelatin / Hide glue - Can be made from boiling hides and/or bones from various animals. Dries to a very durable finish depending on concentration of gelatin. Many colour and strength enhancers can be added for different properties. Can be removed easily by warm water.

[@anonanon7249]

Where did you learn this

[@63256325N]

Your patience is mind boggling. Thanks so much for the great videos.

[@1Bouncy1]

Your videos are the greatest content this website has to offer! And so forth are the only ones I watch with both of my eyes doing nothing else ! THANK YOU!

[@Clickspring]

Great to have you watching mate :)

[@lukealsmith]

I appreciate all of your videos, I am a Mechanical Engineering student at the University of Newcastle in NSW. You have inspired me to work with my hands

[@Clickspring]

Awesome Luke, thrilled to hear that :)

[@halnywiatr]

The sulphur in an egg will tarnish cupric metals black. Any polish with a mild acid (Vinegar with dissolved salt) will remove the tarnish.

[@petergregory5286]

As noted 2 months ago, copper sulphate as a marking finish. It was used in my school workshop so many years ago I’m sure the ancient Greeks knew all about it too. Am enjoying this series of yours as I did the previous. Fascinating! Regards.

[@ScrapwoodCity]

Really elegant work, as always!

[@saxguytony]

How could anyone possibly downvote this video? Your craftsmanship and video production quality is impeccable!

[@natepressel6747]

Hmm. How about the negative of what you did? Soot in the scratches and wipe off the main surface. Its more likely to stay and might be enough to see better.

[@Clickspring]

Yes I think that's going to be very effective, thanks for suggesting Nate :)

[@chromosundrift]

Just wow. For decades as a software engineer I have used watchmaking as a metaphor with little more than a passing knowledge of the techniques and tools but watching your videos has let me appreciate the similarities and differences to my own craft and also the historic context of ancient engineering and the progressive development of the global skill tree of humanity. Thank you!

[@dirtygarageguy]

Blood as a marking fluid

[@daniilkulikov2489]

Yeah... I`ve used it couple of times ; )))

[@jordannewbold8769]

how is this what everyone thinks of immediately? but the problem is that you have to wait a long while for blood to dry so it won't wash off, but then it comes of in large plates when you try to inscribe into the metal

[@needamuffin]

I'm sure this has been suggested many times before, but a Curt calculator seems right up your alley. It's several times more complicated than anything you've done on the channel previously, but a lot of that complexity comes from duplicate parts, the number of unique parts is much lower.

[@Reman1975]

Damn it !!!! I vowed NOT to watch any these until the whole series was done. I got so into Chris's skeletal clock build that waiting for each new video to be uploaded was frustrating as hell. I really wanted to wait till I could binge watch all his Antikythera videos at once......... I failed after only 4 were uploaded. :( Anyway, Brilliant work as always. Personally I haven't got the patience to do all the hand filing myself (I'd be looking around the workshop for a surface grinder to clean up all the rivet heads), But that doesn't stop me appreciating that level of attention to detail in others. Love what you're doing mate, Keep at it. :)

[@actonitecordowner.1571]

Quite a few year ago my wife and I saw the Antikythera Machine in the Athens Museum of Antiquities. It was an exciting day to say the least. My background is mechanical engineering and design drafting. I have nothing but admiration for the work done in these films. The ancient Greeks knew a lot more than we give them credit for. I believe the Antikythera Machine was then result of a lot of developmental work over a very long time. I also suspect other such machines were melted down by the beligerants of the day.

[@keatontaylor3612]

OMFG a new video!

[@herbkephart8130]

Oh my. Couple days ago, after just watching the videos (but not reading the comments) I remembered the request for a substitute for Dykem layout dye. Something that would be available 2000 years ago, that would dry to an adherent finish that would show layout lines distinctly. This brilliant idea came to me--BLOOD! You always have some (hopefully) and it fits all the other requirements. So I reveal this stunning discovery on the patron page. Got back information that it was going to be tried soon. Boy was I proud of myself! I commenced to watch the series again, this time reading the comments--and found out that somewhat less than 40 other folks had had the exact same idea. My head instantly imploded. Should have known that anyone that was interested in this mechanism was far above the average percentile, except me. Herb

[@1tesla]

As always, I try to find my jaw on the floor. Incredible job and video editing. :)

[@goodtimeclub]

I can't communicate just how much joy these videos bring - the work seems so ambitious at the outset, but you make it look effortless by exhibiting conviction & confidence. The theories you present on craftsmen of the ancient past and their mindset/toolset really helps to suck me in your shop with you. Love it.

[@KingPostTimberWorks]

awesome job Chris. how about shellac with an added dye to mark the brass? cheers from over the ditch

[@davidsmart8594]

I was just thinking that...wouldn't want too much shellac in the mix though, eh?

[@Clickspring]

Definite possibility mate, maybe with wine as the solvent? Good excuse to go vino shopping...

[@ExtantFrodo2]

I'd expect that shellac would chip rather that leave a clean line when scribed.

[@eduardvaniersel7535]

I think if you dissolve it in alcohol and apply it thinly it won't chip

[@schmu79]

I was thinking soot, put your mark on, then a light coating of thinned shellac.

[@highvoltagefeathers]

Your craftsmanship and patience are inspiring. Thank you for working to make this available to everybody.

[@Loebane]

I'd like to start by saying that this is my favorite channel by far. I'm wondering, what is the cutoff for where ancient techniques is used? Hand made files, a vise that's just two pieces of leather and wood, but then a lathe with machine driven cutting tools and scroll saw are used as well. I'm not critiquing, I'm more interested in the thought process behind it.

[@ExtantFrodo2]

Lathes ultimately are very simple and accessible tech to those ancient Greeks. Think of "turning between centers" and you can devise quite a few workable options that use nothing but primitive tech.

[@Clickspring]

Great question - Its going to be a blend of the two throughout the build, mainly so I can keep the pace up. But the plan is to verify as much tool technology as I can along the way, that could plausibly have been used by the Ancients. Some of the Ancient tech already covered is just awesome to use, like the vise, so I'll probably use it in every video. Some other tech coming up in future videos is plausible, but just too time consuming to use if I want to meet a reasonable release schedule, so I will have to use some powered tools to get the parts finished in a reasonable time. But by the end of the project, I'm hoping that you will be able to bring to mind a full set of Ancient tools that could plausibly have been used from start to finish. Cheers :)

[@july8xx]

+clickspring: When I started apprenticing many years ago the senior machinist told me his first job as an apprentice was to hand crank the flywheel on a small lathe, it is not unimaginable that the ancient Greeks could have had such technology and all you are doing is replacing the apprentice with electricity. Your use of the lathe is a reasonable step in recreating what they did.

[@ExtantFrodo2]

The milling machine however....

[@louisstout5890]

I've watched all of your videos on the Antikythera Mechanism and they are AWESOME! Keep up the great work!

[@Clickspring]

Terrific to have you watching louis!

[@darynradcliffe2909]

I think ammonia would have been a reasonable choice for a marking die, or even just using the natural tarnish that develops on brass, also shellac lacquer was used during the period....

[@yekutielbenheshel354]

This is yet another astounding video. Chris is a man of many talents. The narration by itself is great. But the lighting, zooming, camera angles, script, and of course the work itself are all outstanding too. This Antikythera Mechanism project is technically amazing and, of course, beautiful but personally I would like to see a future project that is just as artistically stunning but more practical. For example, how about a robot that loads dishes into a dishwasher? Sure, it might not have the "wow factor" of the Antikythera Mechanism but imagine putting a stack of dirty dishes on the kitchen counter and half an hour later seeing them all loaded into your dishwasher. Naturally, such a project might lead to other similar projects which could automate many household chores.

[@gabumonboys]

Perhaps they used dried egg whites with added dye. Many berries could've provided the dye but soot probably would have been more practical. They could have used a water soluble sap from plants. Like the white dandelion sap that was sometimes used as adhesive.

[@regularearthkid]

I remember being told about pigments using egg whites, I was going to suggest the same thing. Makes sense as it can be coated fairly thinly and removed with warm water.

[@WreckDiver99]

Nicely done Chris. Yes, soot was the original marking material...records dating back long ago show this. Gunsmiths still use this today for making firearms (primarily custom high end gun makers). They also used organic dyes as I understand it so you could investigate that as well...

[@hikerbro3870]

I know I'm 4 years late, but wouldn't the simplest way to create contrast for marking be to simply let it patina, or even force a dark green patina with salt and/or vinegar? It would be more than durable enough for extensive handling.

[@oranjizer]

I love how is these videos the rivets just vanish and look like the wheels were magically glued together.

[@henrydegroof4790]

Has anyone discussed the possibility that more than one craftsman may have been involved in this build. Might explain differences in techniques

[@sachie123]

I say it again...you SIR are a LEGEND!!

[@Turborider]

Maybe cover it in wax for marking

[@copelandart]

The wait between your videos is agonizing!! I've entertained the idea of waiting until you're finished and marathon-watching, but by that time, I'm sure I would be living on a funny farm!!

[@Clickspring]

Ha ha! I'll try to get 'em done before then Art!

[@edkerridge71]

litraly dropped my food to come watch this

[@businessgreg77]

Every morning I wake up and have a cup of coffee before I head out to work. I also am a craftsman and that is what drew me to your channel. I am a carpenter. Not quite as precise of work as yours but you are an inspiration to anyone who works with their hands. Amazing work sir.

[@businessgreg77]

Rereading my comment I realized I didnt finish my comment about my cup of coffee. I meant to relay the fact that every morning during my coffee time I watch one or more of your videos. AGAIN.... THANK YOU.

[@Clickspring]

Terrific to have you watching mate, thank you :)

[@LaterMeansBrick]

Maybe the ancients used animal blood mixed with some sort of glue/resin for marking fluid?

[@scottroberts3158]

I wait eagerly for every video you post! I've been thinking about setting up my own small machine shop for around 10 years now, and you have inspired me to finally bite the bullet and take the plunge, I just bought a 10" by 24 inch lathe that was no longer needed from one of my old employers! and I'm now looking for a mill that suites the size and capabilities of my lathe to complement it, as well as a scroll saw, belt sander and the very same vertical filing machine you use as well. All the best to you Chris, you do amazing work.

[@Clickspring]

Cheers Scott, terrific to hear about the new shop

[@Duffman-gj4fs]

Thickened squid ink could have been used as a marking compound

[@zaraak323i]

This is just what I was thinking. There would be a lot of octopus and squid ink around the Mediterranean. I'm not sure it would work.

[@jonathanhendry9759]

The purple dye used for the robes of Roman emperors came from a Mediterranean sea snail, and a related snail was used by the Phoenicians for a blue dye.

The amount of work you do, condensed down into just a few seconds of a section of a video, is just staggering. Not only the time, calculation and effort of the work itself - but capturing it on video, and then the editing process. Astounding work!

[@Clickspring]

It certainly keeps me busy! Great to have you watching mate :)

[@klaxxor]

Maybe a clay slurry for marking?

[@scott98390]

That's a very clever idea, and I think would work very well! Anyone who's thrown a pot would be familiar with the dull matte coating that it leaves on everything... tenacious enough to withstand some handling, but easy to remove. It would also be easy to make, materials would keep forever, be very low cost and readily available almost anywhere.

[@nekomandu8622]

Clax C. Also noting that the fact that clay tight methods were used durring tool making process, clay was available like a water from a river.

[@lawrencelamb9601]

We used something called China White for doing layout prior to engraving. It's basically a solid block of water color paint in some sort of rather sticky base. Water soluble. Wet your fingers, rub it on the block of China White and smear it on the workpiece. Been used for hundreds of years from what I can tell. It holds up to handling fairly well.

[@pratap3369]

the fuck is wrong with the people who disliked this video

[@thebigdecision]

they are those who have built the machanism they are jealous of their secretes

[@jtl1274]

You sir are a master craftsman, and a joy to watch build.

[@jackdewey4298]

The real question now is whether to keep sleeping or watch clickspring.... I think the latter.

[@cptawesome5234]

lol its 11:33 in europe

[@xcy7]

Cpt AweSome Europe has a couple different timezones btw

[@Turborider]

xcy-7 Yes, but there is not a big difference between those, obviously.

[@machine2747]

I love the sped up noise the hammer makes as you drive the pins. Sounds like a little jack hammer. Keep up the great work!

[@eamontreanor1363]

How about animals blood as a marking out fluid.

[@nomad4x]

I was going to post that myself. I would assume that would have been an option.

[@KarlBunker]

For increasing the visibility of marks, have you considered applying a patina to the brass? Sulfurated potash turns most copper alloys brown to black, so scratch marks would have a good to excellent contrast. I think the only way to remove the patina would be to polish/abrade the part, but that should be okay since you do that anyway. Totally love these videos.

[@nolansykinsley3734]

I just realized.... Are you left handed?

[@davidsmart8594]

You'd be surprised how many good engineers are left-handed...starting with Da Vinci.

[@TheKillerjohny]

Good engineers? Sure. Dirty hands from ink and pencil? Sure.

[@Clickspring]

Yes a lefty

[@nolansykinsley3734]

Da Vinci was ambidextrous, not left handed.

[@WormasCZ]

Da Vinci was left handed? Maybe that is why he wrote his notes from right to left

[@pjhalchemy]

Always impressive and full of rabbit holes to wander down, Chris! ~¿@ Thanks! I read most of the 347 comments so far and a lot of good suggestions for a dyechem substitute. Personally I think you used the simplest available but berry/beet juice or even a lichen dye dissolved in vinegar is quite ancient and plausible to me. The only issue with these to me, is oxidation. I'm more interested in the drill tech and how many days it would take someone to use a small bow drill and spade bit to drill those 4 holes for the pins through all three pieces...let alone shaping the pin for a LN3/H7 fit??? Then there is the cumulative TIR of all those gears to keep it smooth running..by hand! That X-Ray type scan was an impressive look down the rabbit hole you are crawling into with gusto!! Looking forward to what ever you bring forward...as always a pleasure and grateful for your great gift to us. ~PJ

[@Clickspring]

Yes I'm looking forward to the drill tech too - cheers mate :)

[@3Triskellion3]

would they have had access to lathes?

[@lordchickenhawk]

+3Triskellion3 Perhaps a treadle lathe would have been possible for them?

[@xcy7]

GitarStu A lathe is a relatively simple mechanism. Maybe lathes existed back then and were powered by water or even by a crank and a very heavy flywheel

[@DirtyRobot]

Or even powered by slaves or apprentices.

[@troyam6607]

foot pedal wood lathes yes. with a tention bar above. same way you do a bow loop and stick to start fire but vertical

[@lordchickenhawk]

+ Troy AM ...like a spring-pole lathe?

[@srirangdhawale5242]

Genuine goosebumps when I saw the finished part. I'd give ANYTHING to go back in time to see it actually happen!

[@nicholasspangler1128]

Hey, just heard there was an earthquake in New Zealand. Hoping you guys are alright.

[@lesdmark]

Considering he is in northern Australia which is several thousand miles from New Zealand, he's probably fine.

[@pauldevey8628]

Chris, I follow you on Patreon. You have found a nice mixture of old world techniques and new world tooling to complete this project. Very unique.

[@Clickspring]

Cheers Paul :)

[@HansP0203]

They used a lot of pigs blood for facial paint so it could just as easily been used as scribing inc

[@More-Space-In-Ear]

I've certainly missed these videos Chris, nice to be put into a relaxed state and guided through the build...thanks mate. Looking forward to the next instalment 👍🏼😊

[@nolansykinsley3734]

One minute since vid was posted, already one downvote... Chris has a hater!!!

[@jiesheng32000]

NolanSyKinsley pretty sure that guy's finger slipped while clicking the like button and he didnt realise it

[@WheatMillington]

Why do people like you care so much that some people downvote? I see this in almost every popular video and I don't understand why you're so personally invested in the up/down ratio.

[@maxdarkdog5051]

@jackson leong +1 ^^

[@nolansykinsley3734]

It is like an unwritten rule that if you have downvotes on your video before anybody could possibly watch the entire video that means you have a VERY dedicated hater, and to be popular on youtube you must have haters. Getting your first true hater is pretty much a right of passage on youtube, and has shown you are transcending to a new level of viewership that cannot be defined by other metrics. By calling attention to it, we faithful viewers show the faithful hater that his singular downvote is essentially meaningless, we will still watch and like the video, we are eviscerating the hater, nullifying the very basic nature of their action.

[@originalusernamefail]

Haterz gonna hate

[@viceskyre]

Your precision is amazing. Nuff said.

[@Q8Police777]

The fact you give this away at the end is mind blowing

[@1forge2rulethemall88]

Your content sir is a diamond in the rough. I'm glad I found it, and I hope you continue what you've been doing. (I came from the file video because I have an interest in ancient tool making)

[@Ropetangler]

You are mistaken, there is nothing rough about ClickSpring, - just pure quality all the way ;-)

[@kevinaustin6971]

Hello Clickspring, one suggestion for a marking solution: medieval manuscripts used egg yolks for yellow coloring. It's durability was described in one documentary as: think how hard it is to get dried egg yolk of your morning breakfast plate. Contrast might not be great but adding a little coloring might do the trick. You do beautiful work sir, congrats.

[@MrHungrySimon]

Your videos are so soothing to watch, like a warm fireplace on a cold winter night. Camera work and clarity of the shots are next to none! Keep up the good work, mate!

[@brad4908]

So beautifully filmed, too

[@thecaptainofrock]

AH MAN!!! I LOVE THAT TAPE THEN FILE JOB!!!

[@Mr.Donahue]

I love how you are showing how everything could have been made back then.

[@kaden56]

Those pins just disappeared! 😳 such amazing work!

[@foadrightnow5725]

Your work NEVER fails to impress me! Simply outstanding! I just wish your videos were longer! With the talent you have in metal working and video production, along with your knowledgeable and relaxed style of narration, you're destined to have a show of your own on the Discovery Channel or similar channel!

[@westonmeans7321]

Great start to any day when Clickspring uploads a new one. Becoming a patron today. Great work.

[@Clickspring]

Cheers Weston, appreciate your support, thank you :)

[@MichaelGedies]

Simply breathtaking. I've never clicked a video so fast. Please keep up the great work

[@cylosgarage]

great thing to wake up to before work

[@vulpsturm]

Instead of candle-soot, they ancients probably used "lamp black", which is the same sort of thing, just originating from an oil lamp. Great channel!

[@markschwegler1100]

Such a glimpse through the keyhole of time is rarely seen. Thanks for that!

[@MrWisski]

No, geared mechanisms are NOT my thing. Yet I find these videos fascinating and am sad that I can't binge the entire process from start to finish. Beautiful work, can't wait to see the finished product!

[@alexandermcalpine]

Just FANTASTIC!

[@amofilmes1]

If the mechanism was made out of Bronze or even cooper, you can add Vinegar, so it would oxidise the surface, this way it would create a better resistant green surface, that could be removed later. Of course you did have to overshoot the size a little to counter the corrosion, and you did have to do it before you made the gear "teeth". Another option would be a either a die (used in cloathing or some kind of pitch or some stain liquid. I did discover your youtube channel by searching about case hardening, which was a great video, keep up your good work.

[@PieceMaker]

The sound and image quality of your videos is just mind blowing. Found you through Instagram. I hope one day there will be a video about the camera and audio equipment you are using.

[@DaveCraineAccidentalAquarist]

You may be the most patient and meticulous person on KZbin... amazing.

[@justing1810]

Looks like a really challenging project even with modern tools

[@davidthorn4394]

Back in the late 1940s/early 1950s I spent all my time with my grandfather when he was in his workshop. All the walls were covered in wooden drawers, large below the bench and small above. When he wasn't at home I used to investigate the contents. I remember finding a chunky box made of thick cardboard, ex Ilford film I think, which had blue crystals inside. When he arrived home that day I asked what they were used for and was told that they discoloured metal so that if scratched the lines would show up. I have not done any in depth research but I am fairly certain that the necessary materials and conditions would have existed to enable an ancient Greek Clickspring artisan to grow his own blue blue crystals. His supply of copper, at best, would have been in the form of ingots but could have been much less refined and the crystals could have appeared naturally during storage. Certainly it would have been common knowledge in the metal working community. Playing with Copper Sulphate crystals with bare hands is not something that I would allow my grandchildren to do but hindsight is a wonderful thing. 75 years on from that time I have nothing but admiration and gratitude for the care and patience he took to impart his skills and knowledge to me. That input has helped me in my working life and now as a hobby. As I grew larger I used to treadle his lathe for him whilst he did the turning, it is in my workshop but it is now too much effort for me to use it. I found your videos by accident and they have given me great pleasure.

[@Remops]

This guy is a GD genius for being able to recreate this fascinating analog computer, even with mostly modern technology and techniques...... Which of course begs the question; HTF did they do this over 2k yrs ago without these advancements, and to such a staggering level of complexity and precision. I NEED TO KNOW! UGH! Really great video series.

[@billyw1345]

It's easy to assume people of yesteryear were stupid, they were every bit as clever and intuitive as we are today. I am sure they were way more sophisticated than we give them credit for.

[@ChannelJeffrey]

4:31 watching that pin float into place is very satisfying

[@sergedaney3511]

This is so great and so well done... video is super pleasing to watch (can't wait for MOAR lol)... hats off to you stranger!
