- Antikythera Fragment #6 - Ancient Tool Technology - Making A Hand Powered Drill
The precision of the holes in the Antikythera mechanism is one of the most fascinating aspects of its construction. In this video I make a tool that is capable of creating holes to the required standard, yet is consistent with the level of technology known to have existed in the period.
The video where I show the drill bit making process in detail can be found here: • Antikythera Fragment #...
The plans for this project, and a IGES file of the flywheel casting pattern can be downloaded as a zip file here (11mb): www.clickspringprojects.com/up...

Abbreviated Transcript:
02:30 In fact the Roman author and engineer Vitruvius, writing at around the time that the mechanism was lost mentions lathes in a completely offhand manner, expecting the reader to be thoroughly familiar with the idea. As if the technology was so commonplace, that it barely required explaining. As it happens, the Antikythera Mechanism may in fact be the very best evidence available to establish the full extent of that lathe technology, at least as it relates to smaller scale engineering.
08:37 Next up are what I'm calling the collets, The parts of the tool that'll hold the various drill bits. I cast some long round stock from the same bronze as the flywheel, and then turned it down to an appropriate starting diameter. I then formed the basic collet profile.
11:15 And the same applies to these holes. They're not difficult to form, nor do they need to be terribly precise. They could be made using the lathe tech of the day, or even by using much cruder methods like gouging and then filing. To complete the part, I gave it a light sand, followed by a linseed oil finish.
16:12 In any event, once created, the drill bits themselves can then be used to drill out the collets. Each of the 3 test bits correspond to a critical feature found within the mechanism. One is for a standard bearing hole, one for a standard retaining pin, and the smallest, coming in at just 0.8 of a millimeter, corresponds with the holes used to locate the calendar ring.
16:39 Now there is evidence of the use of soft solder within the mechanism wreckage, and certainly soft solder would be suitable to hold the bits in their collets. But equally plausible, and I think a little more convenient, is resin. I'm using shellac, but any hard resin available at the time would have worked well.
19:58 The changeout of drill bits and flywheels is fast and easy, and the drilling time is comparable to a modern drill. Now as to whether or not this type of tool was used to build the mechanism, well who knows. But I do think its fair to say that its a contender. These test pieces compare well with the holes found throughout the wreckage of the mechanism.

As a historian you are a hell of an engineer, or as an engineer you are a hell of a historian.
Either way, this is far and away the best historical engineering channel on the interwebz, at least as far as I have found. Thank you.
Cheers John, terrific to have your support mate :)
Bolton, Watt, Murdoch, Maudslay, Bull, both Brunels, Smeaton, the Stevensons ... and now ... Chris of Clickspring ...
I think he ought be known as an Archaeological and Historical Engineer ...
Hi John. If you're actually looking for that sort of thing here is a few good ones. th-cam.com/channels/fsznjef2zGJnrCRQBXqo6Q.html
Europiddles - So that would simply make Chris a Master, thereby clarifying the OP's query. Why the ire?
Hard to belive I was only a boy of 12 when he started the Antikythera mechanism project, and now im a father with 3 lovely children of my own. I can only hope one of my great great grandchildren will be alive to see it finished!
Could always make one yourself?
Nothing when compared to "Project Binky", I made a comment last year that someone probably went from being single and broke to married and succesful. Few guys replied how their lifes changed during the series, but one guy actually met his future wife and married her like few months ago. Good times. At this point Im not sure why Im even typing.
Ohh, yeah, this series isnt that long and actually, if it weren't for that break, I would consider that it was fastpaced :P
Coalition of Rob only if you help!
Mindblower, Project Binky sure is a match to Clickspring in Perfectionism.

absolutely brilliant.
Thank you mate :)
Hey Tony, vs Chris is difficult to compete :)
Uuuh ! Tony is here ! Maybe Stefan and AvE can come later to share a beer
i figured youd be here
I have been watching ToT long before finding Clickspring, was wondering when I'd see your comment. :)
Dewalts new brushless drill. Looks great.
wrong color
Brushless, cordless, batteryless, and motorless
This is great Chris, but can you explain how the ancient greeks filmed and edited their TH-cam videos?
Well, after all, they *did* have the first (non-programmable) "computer" ;)
Probably with a Nokia.
Technically it was programmable. You just needed more rope. (If referring to the robotic carts/actors in the theatre. While not computing of it's self, it could be setup as a turing machine theoretically ;) )
Thumpert the Fascist Cotton-tail they used αδοβε συν επ and they uploaded in ΣυΣωλην
“I’m using a high definition digital camera, but it’s easy to imagine you could get a similar result with some vellum and simple charcoal” ;)
Utterly unreal!
Alec Steele impressive casting technique but didn’t have me rolling in laughter like you did when casting!!!
Alec what are you doing over here in The Aus side of youtube
Breaking down these steps for tooling- or blacksmithing - shows how intelligent people of the day really were. Often times, not given enough credit or just completely misunderstood. Absolutely fascinating.
Alec: But it's real, special for you, in your projects in Montana. All good friend.
Great minds think alike
Best and most meticulously crafted sand mold I have ever seen. Not the typical TH-cam "I just put this together in 2 minutes and it'll have to do... oops, it screwed up the project, oh well subscribe..." kind of crap.
pain felt
relief also shared
Having made a few of these over the years I can safely pass on this one piece of advice - make the shaft and entire assembly as long as your forearm so you can rest your elbow on / beside the piece and hold the knob in a braced fashion for absolute accuracy. If you're supporting it free floating you may get drift and wallow the hole. If the entire drill is as long as your forearm the bracing effect will mitigate it almost completely allowing you to operate like a drill press.
Brilliant! Thanks!
You can also build a jig that can be fastened to your workbench or the surface you're drilling, thus making sure the drill stays upright all the time.
@@2110sebas I'm sure if anything was being produced at scale that required a lot of drilling, they'd be using something akin to a manual drill press so that both arms could be used to rotate the drill.
@@namAehT That would make sense.
I also wonder why it is presumed that "hand tools" couldn't have a drill press operated by something like a sewing machine foot treadle.
By the time Chris is done he’s going to have a deeper understanding of the Antikythera mechanism than any researcher.
Seriously, he should be getting university research funding for this.
I'm inclined to agree with you. This is archeology, and it's fantastic. Only problem is the bureaucrats wanting to take credit for Chris's hard work.
They fund you , they control you
@@davidlawrence8085 what?
@@yeetman4953 pretty simple. The man said, "They fund you, they control you." Meaning if you take their money, you must do what they say.... If you dont take someone elses money, then there is no one telling you what to do... Its really a simple concept do you understand now?
@@jonross377 thats usually the case when donors arent disclosed. Usually it isnt bad
Two Clickspring videos in one day. Today will be a good day!
I was barefoot when you scraped and disposed of the slag. It made me flinch. Lol
Holy heck that is a satisfying click of pressing the bushing into the handle @ 12:18.
You've made some very smart casting choices!
Thank you mate, terrific to have you watching :)
+Hand Tool Rescue I agree. Watched a few other people casting and they were having no end of problems. The methods used here will solve all of their issues. I am thinking Clickspring has done quite a bit of casting before.

Even your sand mold planning and execution are immaculate. Most impressive maker on TH-cam!
Totally agree 👍, this dude is Awesome and these videos are a gift to craftsman and anybody who loves history 😀 ❤️ 😮
It's been at least 10 years since I've looked into home metal-casting and your video just blew my mind multiple times. (And i'm not even half way through) Sometimes I forget how much is lost between seeing someone perform an action and reading about it. They may have been mostly overlooked, but seeing the pour cup, sprues, and care taken with forming the casting molds was something I have forgotten i needed to see. Thank you.
Imagine how freakin' good this dudes sand castle building skills must be!
I had the same thought
IKR?
I could never do what he does with metal, but I'd love to work on my sand skillz!
😀
This is one of the most beautiful makes I have ever seen in my whole life!! Well done, congrats!!!
The thing I love about Clickspring videos is just how many corners that you refuse to cut and how little you seem to concern yourself with the "time wasted" doing smart things like cutting your runoff pool on your out flue in your sand mold. There is so much in all of these videos and yet it never feels like either wasted time or effort, nor hurried to completion for the sake of completion.
... Guys I think Clickspring's actually a wizard. Change my mind.
Nope. Not even gonna try.
My wife and I are in Syracuse Sicily (March 2024).
We were wondering about the tools ancient societies had. From Archimedes, to the Antikythera mechanism, to potting wheels and drilling devices ... here we are. Early on, I suggested to my wife "he's a Kiwi".
Absolutely well done. Fascinating stuff.
I hope your family is understanding and accomodating - especially when you're mid pour with the crucible and your young teenage daughter wants a lift to hang out with her friends ("Dad, can we go now?!").
Reminded me a lot of John Britten casting items for his motorbike (highly recommended)
Man, turning a piece of metal on a lathe that you cast must be so satisfying.
Seriously Chris, what can't you do? You do crazy machine work, perfect
turning jobs and you have godlike mill skills, and now you cast this
piece like it's no big deal... What can't you do, what haven't you done
yet? I'm in awe.
"Thanks for washing. I'll steal your lighter!"
Nobody Important "get I, grizly here and welcome back to clickspring"
keep your click in a vice
It is always a joy to watch a craftsman make a complicated operation look easy.
I love that half a decade later you've just dropped the video on the lathe technology of the time and now I'm back here watching this, it all makes perfect sense. You are an absolute genius, sir!
I restore antiques and I feel that one day we will be saying “ I can’t believe that was done without a cnc machine ! The ancient skill that I’m most impressed with is the infinite patience and determination to complete extremely long and somewhat arduous tasks to an extremely high level of precision, like making your own files and drill bits. It takes an attitude that’s not found very often these days. Quiet ,focused, each millimetre just as important as the next. I see this in four hundred year old marquetry or beautiful finials turned on a pole lathe or three hundred hand cut dovetails in a large chest of drawers.
These videos help keep us aware of our ties to the “ handmade world “ of our past..
Education at an almost intoxicating level.
Funny thing is when you make things by hand it doesn't feel arduous, or that any special patience is required. It just feels..right. I'm not good at writing so I don't know if this will make sense but it has something to do with a craftsman's relationship with time. As an example: At my old workshop on a farm I reshaped a hatchet with a file to make it able to plane a surface flat.
Every comment from the people coming and going was about how long it would take or Blimey you've been doing that for hours or Haven't you finished yet?
When it was done every person I spoke to said How long did that take? Simple answer is I don't know and it doesn't matter, I had to do it and so I did it..and was at peace for every second doing so.
Anyway, bit of a ramble, hope it wasn't too boring to read
yeah they didn't have the tech but they weren't idiots this is amazing
This is the spectrum between actual hands-on experience, the ability to reduce the complex integration infinities with hand-eye feedback, and the art of designing an operating sequence of effective and efficient applications. Equivalent to the "Mathematics is Beautiful" deconstructions of Conjecture, into self-consistent sequential steps, or the precision of Surgical Procedures etc.
2 videos in 1 day? It's a dream come true!
Feel like I'm watching a good episode of How It's Made.
Sending this video back through a time-hole.
Hi Chris,
I very much enjoyed your video. Many years ago as an apprentice I was taught to make drills for what we called an Archimedes drill which might or might not be a correct description. The drill was a lot simpler than yours: a steel shaft with a transvers hole for a leather thong which went straight through not being knotted, the wooden drive bar was turned with holes at its end for the thong. The disc weight was a piece of cast lead there was no chuck just a hole about 6 mm diameter. The spade drills we made were forged with a square tapered shank. The tip of the drill was hammered flat so wider than the shank, after the tip was formed its edges were stoned to the required size it was then hardened and tempered. A piece of wood with a small hole drilled in its centre was turned to a tight fit in the 6 mm hole in the drill where it was tapped in; the tapered shank of the drill being tapped into the hole in the woods centre. The drill was used one handed the other hand being used to hold the work piece. Take care and stay safe.
Terrific detail Tony, many thanks for sharing :)
First time I've seen a proper pounce bag on a TH-cam video - by far the easiest way to apply an even coat of talc as a release agent when ramming up a mould.
What's a good material for a talc pounce bag?
Michael Ennen I have no experience but I would think cloth from an old thin t shirt with a bunch of talc and tied with a string. The particles are so small they should go through.
@Michael Ennen Nylon stocking works well for me.
I just let this here:

Just came from the future to thank you for the fascinating lathe video.
Probably the best example of mold casting I've seen a a while
Are you a foundryman ? Lot of skill in what you just did. Runners and step gates, nice way to keep the metal clean. That pouring trough for the sprue was also a nice touch. Just wondering.
While DIYs are great, it's really nice to see a master craftsman doing it the right way. Thanks!
Drilling such a precise arc of holes would be a challenge with modern equipment. Very nice.
Fantastic!
Who the hell downvotes these?????????
2?!?! Ohh Clickspring, you're spoiling us!
I find it interesting that the drill you made is essentially just a very refined version of a primitive drill made of sticks and rock and tree twine.
Clickspring youtube channel is priceless
O take my hat off, and every hat I will wear for you . The professionalism is unsurpassed. Truely masterful !
You amaze me every time you put out a video Chris. Not every orther time, not “its pretty good except for that bushing video”. Every single time, my eyes open a bit wider as you demonstrate how persistence, accuracy and knowledge can create something amazing.
Thank you mate, very much appreciate the encouragement :)
I’d like to see you make an ancient lathe.
same
Yes. I've always wondered, how was the first lathe made with no other lathe around to make the parts.
@D good Father
@@divermike8943 Well, they did have spring lathes for a very long time (lots of video's on how to make them, no lathe's required) and then you also have builds like this: th-cam.com/video/zPGZg45dGXA/w-d-xo.html which, although not historically accurate, does show how to make a more modern lathe without a pre-existing lathe.
@@divermike8943 I've found this paper on the subject, not super long and there are a few pictures that show antique lathes, usually only made out of wood and ropes: www.academia.edu/3994508/Early_Evidence_for_the_Use_of_the_Lathe_in_Antiquity
I assume these are more for wood turning, just like what Robin Wood is doing with his simple foot powered one : th-cam.com/video/GLpNNf4V5lU/w-d-xo.html
So, probably not really suitable for metal, especially harder metals, but it's a base.
Hope it helps.
My grandfather used this tool in his career as a diamond setter in and around the 1920s and 30s. Great video.
My great uncle was a jeweler and set diamonds, he used one of these. Thanks for bringing back a valued piece of mechanical history... brilliant!
3 years late to this video but that was absolutely outstanding. We take too much for granted nowadays and I watched this in total amazement at how simple and effective it all was, great work sir.
Between this guy and Primitive Technology I just can't decide.
They should colab and make an artisan's workshop from scratch.

Almost forgot to clean the end of the thumbscrew.
Chris you make the best videos I will become a patrion as soon as I can afford it I love your videos and want to see you continue
I have seen medieval illustrations of this type of drill being used in conjunction with a long hinged and weighted horisontal beam across a workbench. the top of the drill located into a socket in the middle of the beam to steady the drill and presumably improve accuracy in drilling. The weight could move along the beam to vary downward pressure. It would also mean that drilling was a one handed opperation allowing the other hand to steady the piece or apply a cutting lubricant such as tallow. Do you think this method could date further back. Once seen it does look like quite an obvious method.
Clickspring As usual, a wonderful and beautifully presented video. Your skills are magnificent. I was wondering when the next installation would be..... Superb, and well worth waiting for, well done Chris.
Clickspring If you ever wanted to experiment with gut threads or cables, you might want to look in to sourcing gut strings from classical string instruments (violin/cello etc.) They aren’t overly difficult to obtain (a touch pricey though...) They are still in use for players who play in orchestras that use period instruments.
They’d provide no specific mechanical advantage, but they’re probably as close as you can come to replicating the tools and materials of the day.
Ancient Greeks were as creative and talented, as you are. For sure!
everytime a Clickspring video is uploaded, i feel speechless for the overall beauty of this project....
You're a Gladiator Mate !
What precision and beauty! On many of the videos I watch, I always keep one finger on the right arrow key to move more quickly through them. However, with this one I just sat back and watched. Interesting and well done the whole way through.
For what it’s worth-Oh MY GOD!!! I love this! Years ago I employed a heap of alloy and iron casting in my art studies and work....seeing this just swept me away......
They don't come any more talented than this man.
You make it look sooooo simple... MAGIC !
Hi Chris, It’s great that you make these videos because it gets people interested in machining who wouldn’t normally be interested and hopefully this will prevent skills from being lost. I’m an Electrician by trade and I ended up in a dental service job where I’d have to repair all kinds of mechanical hand pieces that had a lot of aluminium parts that often ended up with frozen threads after being sterilised countless times in a steam steriliser. The boss would encourage us to make tools when needed and I ended up with good fitting skills as a result. One of the best tools we had which might be a good thing for you to make for yourself was a 30 degree V block, which will have a lower centre of gravity and is a lot safer when trying to do things like unscrewing a seized screw at 90 degrees to to the body of an assembly as a 45 degree V block would often end up toppling over when you’re exerting yourself. They are really handy and the boss got me to make another one before I left that job.
After that job I got involved with air conditioning where my acquired fitting skills was appreciated and this is why I’ll be sending a link to your channel to one of the guys I worked with in that job.
Another idea for a project for you that I did while in air conditioning was a tool for removing blown indicator lights on control panels. They were often not replaced because they are usually recessed inside the fitting and it’s very difficult to grip them. I simply got a piece of 10mm PVC rod, made a knob out of 20 or 25mm rod and drilled a hole through it and made it a tight fit at one end of the 10mm rod and on the other end I got a 44 magnum shell case and screwed it to the other end and then I got a thick walled piece of silicon tube that was a snug fit inside the shell casing cut to a length so that it stuck out about 8mm. It worked well and every one who saw it wanted me to make one. Hopefully now there aren’t control panels with half of the indicator lights out all over the place.
If the Greeks were smart enough to develop this kind of drilling tech, they would have been smart enough to design a frame to hold the drill! Brilliant work you have there.
I don't doubt that one bit.
It's great that your focus is ancient tech.
Excellent concept for a channel!
Ancient history, machinery, craft, all in one video. Thank you.
I never needed something like this but just from seeing this video, I bought a Sherline 4100 Lathe and now I have a hand powered drill...

It fascinates me, that there are lots of power tools needed to make simple, over 2000 year old tools.
You've gone down the rabbit hole! You're a hero! Great video
What's most amazing is how such simple tools can be used to create the most exact mechanisms. I remember a document about how, in the 1300s, many of the first wheels for chronometers of the time were divided out using a compass, by walking the tips along the edge of the wheel.
Clickspring has a video where he does exactly that, then builds a simple tool to not have to do it anymore: th-cam.com/video/BIUAdINXZmQ/w-d-xo.html
Chris, your work is second to none and positively hypnotic to watch. Mind blown.
Thank you mate, very much appreciate your support :)
And speech... it is so easy to Non-english speaker to understand.
really enjoy your whole antikythera series.
Ancient temples in India, Cambodia, Sri Lanka, etc has used lot of ancient technologies and make mind blowing sculptures and temples
You deserve more than 300k subscribers. I've seen vlog channels with 1 million+ subs that put less effort into their videos
Absolutely enthralled. Chris' level of skill and attention to detail in every single aspect....beyond words! Just love his videos
Thanks for unveiling history. See ya ladder.
As always, a privilege to watch.

That cast flywheel was absolutely beautiful!
Excellent 👏,no more words describe your knowledge, skills , efforts
Love from India
A very well made hand drill, such as the one in the video, could've opened a door to many possibilities within the ancient world.
Wow I never get used to the level of workmanship. This guy is just impossibly meticulous.
This is my favorite video in this series because it shows something unique about the human race as a historical mindset. For one, we know without a shadow of a doubt that Homo Sapien was never at any point "less smart" than we are today. They shared the same thought processes, capabilities, even humor - memes and derp humor are older than written language. Second it shows how vastly powerful our skillset was before hand. The time and effort it took him to do this with modern tools and "practical" equivalents is nothing compared to the individuals who invented without industrial lathes - I also have a feeling that if you time warped one of those people to supervise him during the middle of them being in awe of the tools they'd still have a point where they'd say "You know, there's a less dumb way to do that I can show you." Third the Antikythera object was dated to be only about 30-60BC. That's RIGHT in the range of Vitruvius' De Architectura c15-30BC. The defining book of all western technologies based on skill and determination of mind. He didnt come up with this. It was a teaching based on teachings. The people who built this machine were the same people who taught him how to create empires, polymath, acoustic logarithms to place vases of different sizes and weights to resonate with operas to sympathetically reverberate and enhance the sound of singers tenfold throughout an open theater. Imagine what the world would have been without the burning of Alexandria. This video gives us a small glimpse
Hands-down, that is the most skilled metal working and craftsmanship I have EVER seen!
The best video I have seen so far.
does anyone else think that these films are hypnotic
Over and over, I noticed the only thing my inner voice was repeating was, "Wow, wow, wow..."
10:12 "I roughly marked out the square"
.
And proceeds to hand-file a perfectly centered, perfectly square hole.
As if mere routine!
.
Given that an off-center hole would lead to imbalance of the whole drill, your confidence is *staggering*.
(and justified, unless you have a whole drawer full of misshapen flops that you are hiding)
@@JohnDavis-im1oy My father-in-law tells me that a similar test was used for prospective emploees of public sector engineering companies. You were supposed to file a star-shaped hole and the matching star out of iron sheet, so that when diesel fuel was poured over the assembled parts, it should only drip through.
@@frankieromnimon5898 That all sounds like an unbelievable amount of busy work. I get bored 2 minutes into filing something.
@@scholargrizz7071 Yes, you suffer from computer-burn just like all of us westerners in this era. I myself find it difficult to get unglued from the screen, but once I escape down to my basement machine-shop (of sorts), I have some quality time fixing something that would otherwise be discarded (because everything is so cheap to just buy and then throw-away), or making something that hardly anyone would bother building for me unless I paid him a thick wad of hard-earned money, and maybe not even then . It is a very satisfying pastime.
@@JohnDavis-im1oy I was apprenticed to Ford and was one of only 3 out of 15 toolmaking fitters who completed the accuracy block in our first year... all done with one large flat bastard file... the supervisors mucked up my roster at one stage, I'm sure trying to make me quit and I ended up doing 5 straight weeks of filing that block of rough cast iron to flat and square within four thousandth of an inch (4 thou)... fond memories... people are occasionally amazed at what I can do with files these days...I do feel lost without a file in whatever tool kit I'm lugging around...
i dont own a single tool he used in the making of this device, but i love watching artists make these amazing things..... absolutely brilliant piece of craftsmanship 👌
everytime i watch clickspring video be it 22 minute or 30 minute, my mouth would be gaping wide for as long as the video runs
Awesome, as always! My family always drops everything they're doing when you release.
Awesome, so pleased to hear that :)
Makes me wonder which would be more efficient, this or a double pinion hand drill... or to be fair any form of hand drill without electricity. But I digress, this is an excellent video, yet another example of you bringing historical engineering and craftsmanship to life. Amazing work Clickspring :)
This channel is another world.
That click when the collets snap into the square hole in the flywheel is very satisfying.
Lovely video as always. Fascinating to see these ancient solutions to tools we take for granted today!
Beautiful, just beautiful! And without any commentary needed, you casually learn every step of casting :D
Wow. What a Craftsman!!
its nice to see someone pull out all the stops on casting prep.
With all of the complexity of the device itself, I'm thinking that it probably wouldn't be too much of a stretch to think that they probably would have made something to mechanically hold that drill vertical to reduce wobble. Thanks for another great video. Chris
Definite possibility - I found bracing my arm on whatever I could find nearby worked fairly well too - Cheers :)

As it was by coincidence that I found this video, it is a cosmic plan that as I scroll the sideline of videos that I would find your answer to this pump drill as a drill press. Here is the link to that video: th-cam.com/video/9D__A2gK2_o/w-d-xo.html
Beautiful tool and video!
I LOVE your furnace design!
Amazing craftsmanship. Absolutely marvelous
A "normal" person can think 2-3 holes are OK to test the new tool... You tested it with 41 holes ! Inside a circle ! :D Hehehe ! You have the patience of the ancient oriental artists... Cheers from Spain, almost exactly in the other side of the globe !
Ooh! Two videos at once! This must be my birthday!
Cheers! Keep being awesome!
This is excellent Chris, we can't thank you enough for sharing your ideas and insights into ancient technology. In my view, you show the simplest way to achieve the accuracies needed. More complex stuff would be possible too I guess, but I find your solutions very elegant! Thanks again!
Thank you Markos!
What do you use for your 3D computer models, including the animations?
I use Solidworks, although have a look at Fusion360, its free for non commercial users - Cheers :)
Ok great. I already use Fusion360 (this is how I made my model) but have no great experience with SolidWorks. For the rotations of your virtual model (especially the planets with retrograde paths) did you use some physics feature of Solidworks (i.e. real touches of bodies) or simply put some math equations? cheers!
