Abbreviated Transcript:
00:36 The purpose of the escapement is twofold: Firstly, it releases small amounts of energy to the pendulum to replace what it loses to friction, and so keep it oscillating. And secondly, it effectively counts those oscillations, and through the attached gear train keeps a running total, that we see displayed as the time.
01:45 Old fashioned trial and fit on a depthing tool is still the accepted method to inspect the escapement action, and decide on the required adjustments to the pallet profile. The process of roughing out the pallets is much like you've seen in previous videos for parts like the click and clickspring. A paper template marks out the perimeter, as well as the hole location on some O1 tool steel.
04:29 And at this point the recognisable shape of a set of recoil pallets is starting to emerge, although there's still quite a lot of fine adjustment required to get them to perform correctly.
06:00 But the general idea appears to be gradual removal of excess metal, whilst incrementally pushing the pallets into closer engagement with the escape wheel teeth. The ultimate goal is to have a minimum drop onto both the entry and exit faces, and an easy clearance at each of the discharge corners. While at the same time ensuring that the pallets at the correct theoretical depth.
07:52 Like most of the other steel parts in the mechanism, its important that the pallets be hardened to ensure they have a long service life. And you might recall that when I made the hands, I used a custom tray to contain the boric acid glaze during the heating.
09:22 All pallet surfaces now have the required finish, and I used a fine oilstone to break the sharp corners, and leave a presentable edge. So with the pallets complete, along with a small fastener that I turned up off camera, I can fit them to the mechanism and see how they perform.
10:55 But with a slight turn of the bushing, the drop can easily be minimised to what it should be for maximum energy efficiency. The escapement feels nice and slick. In fact a light touch on the center wheel is enough to set the pallets off and running, and the bushing can be further adjusted so that the teeth just pass the pallets.
14:20 The spring is then wound up just enough to allow the barrel to be slipped over, and then the barrel hook is engaged with the outer hole in the mainspring. The tension can then be slowly released by reversing the winder, and once all of the force has been removed, the spring can be unpinned.
14:58 A few drops of oil are enough to lubricate the coils, and will be enough to eventually cover the entire length of the spring as it's continually discharged and rewound.
17:42 Its not a long enough test period, and its unlikely that the clock could maintain this performance long term, particularly without temperature compensation or a fusee. But its an encouraging start, and certainly a much better result than I expected. I'll leave it running on test over the next few weeks, while I work on the last remaining components of the build: The stop work mechanism, a winding key, and of course the final polish and assembly.

People who wonder why old style clocks cost hundreds if not thousands of dollar really need to watch this series. This is easily one of my favorites series on youtube.
Seeing the clock finally tick made me smile. BeautifulWork.
How long did you sit there watching everything tick the first time? After watching this being made for who knows how long seeing it all together really put it in perspective. There's so little material there!
Could not take my eyes off it! Kept going back into the shop to check on it like a baby for the first few hours!!
it's amazing that the clock is now running. it's feels like ages since i began watching and it's great to see the clock run for the first time!
This clock will outlive you (compliment) and become a wonderful artifact for generations to come.
Especially with this excellent tutorial series to compliment it. I really hope that all of our videos remain online in perpetuity. It makes me feel like an ancient Egyptian, leaving a record of our passing.
Previous generations left copies of their knowledge for subsequent generations through written text. Our generation it is Web and Video instruction.
Paul Devey That's a very bad thing. Paper can last for hundreds of years, but a normal CD or flash drive fails within decades. It's a real problem called data rot.
That escapement makes such a satisfying tick.
Seeing that clock ticking away for the first time must've been like seeing your newborn take its first breath. Amazing dedication and attention to detail, Chris!
Very much so! Still find myself sneaking back into the shop to check on it!!
I don't think anyone one could resist doing so. What do you plan to do (channel wise) after this clock has been polished and assembled?
Any time something you make something off-camera, I'm a little disappointed. I want to see every screw made. Seeing the love you put into every piece makes me so happy.
I was not expecting such emotion at seeing and hearing it work. I can only imagine the greater degree to which you experienced that. What an incredible process. Thank you for your dedication to both your project and the unparalleled documenting and presentation of it.
Yes! I was totally surprised as how excited I was about this. What a great series. Seems like he's somehow tapped into something deep, something about the joy of craftsmanship.
I would bet for most people who started watching from the early episodes had some tears in their eyes when they finally hear the ticking sounds at 16:00 ... I know I did
Rexus King No I didn't! You can't prove it! ;)
I'm glad I wasn't the only one feeling these emotions. I felt a bit weird, grinning at gears ticking!
Yeah, I make it about 18 months I (and about 350,000 other people) have been waiting for those ticks. I can only imagine how it must feel to have built every part of that...
I love when you say you do something to "leave a presentable edge" somehow implying it wasn't presentable till that point.
Never thought a clock could bring this much emotion to me
Terrific to have your support Leonardo :)
I replayed the first ticks a million times,one of the most beautiful things I ever heard.I hope whoever gets this clock watches all of these videos and know what a true masterpiece it is!
AvE is the gateway drug into the wonderful world of machining. I'm so happy he gave your channel a shout out.
absolutely one of the best machining vids on youtube
You're getting so close to the end of the project, but I need this channel in my life. Please consider building a fighter jet when the clock is done.
when the whole project is finished , i'll rewatch the whole series. already did it twice.
So satisfying. Awesome work!
Thank you mate!
I'm so glad this series appeared in my suggestions.
Wow! Hearing the ticking almost made me cry :')
Just came across your channel from the UK. My father was a precision engineer. He's gone now but so many memories of patience and attention to detail come flooding back. Many thanks.
Terrific to have you watching Colin :)
Out of the 90+ channels I'm following, this is definitely top 3. Fantastic craftmanship, congratulations on the great milestone, you had me grinning like an idiot in front of my screen.
and what are the other two in your top three?
just curious as might be something good ive not yet seen. cheers
Well, I never actually made a top 3... But I guess "Bad Obsession Motorsports", "SV Seeker", "Petrolicious", "Primitive Technology" are the first ones to pop in mind when it comes to competitors. :-)
Great minds and all that...the Bad Obsession boys are a lot like Chris. The projects couldn't be more dissimilar, but the attention to detail and making sure everything is just as it should be...it's what makes a project great, instead of merely alright. :-)
Me too! It must be a love of engineering in many forms!
g0fvt That, and a sincere appreciation for quality workmanship and doesn't believe that near enough is good enough.
I don't know what I will watch once this is finished. I will have seen what must be one of the very best series/build there will ever be on youtube.
Terrific to have your support Carl :)
I've been with this clock making series since the beginning and I have to say, I truly smiled and felt extremely happy when I heard the first few clicks of the clock.
Cheers Isaac, very much appreciate your ongoing support :)
I totally agree! I look forward to every new video but this one is the best yet. When its 100% complete Chris should set up a live webcam so we can see the clock ticking, real time!
Oh this is a great weekend! Esteban Chaves claims 3rd in the Vuelta a Espana and we get a new clickspring video!
Man, clickspring is a really diverse channel in terms of talent. The narration and videography are excellent and the craftsmanship and artistry of the clock are superb.
I had to smile in spite of myself at that first tick tock. It's finally coming together.
I just bought my first bench top lathe because of you Chris thanks and btw awesome video
I started off small like that too, but then it just kept getting bigger and bigger. Now it's up to 27in's.
+TEXAS - Did you just use water or did you use a growth hormone?
+Mick S - A good and willing wife will fix that.
I used cash, bundles of cash.
what lathe did you decide on?
Absolutely stunning. It is such a pleasure to watch a craftsman who takes such care in producing the finest quality. And the same goes for the video quality--I cannot understand how so many UA-camrs think it is satisfactory to constantly produce shaky blurry videos with rambling or zero commentary. Your videos are the polar opposite of those, and a refreshing joy to watch.
Cheers tad, very much appreciate your encouragement, thank you :)
Congratulations Chris! Hearing the clock come to life was so awesome, I can only imagine how excited you must be!
Thrilled mate!!
This video deserves 1.000.000 views..
Very big milestone. I was surprised that you could get away with oil quenching in that big tray. Shows that there is more room in the cooling curve than I was taught! Thanks again!
Yes its been a bit of a revelation to me too! I fully expected it to not be fast enough with the hands either, and at the very least to get some differential cooling distortion, but it works without any issues. Terrific to have your support mate :)
Man. I was just sat here with a stupid smile on my face while you started the clock for the first time. So cool to finally see it moving!
I hope the BHI present you with an award when this is done, not least because this excellent series of videos is surely inspiring a whole new generation of potential clock builders. I'm also hoping that when this is finished, you start another project for us all to enjoy! J
I verbally cheered when you dropped the pendulum! From the couch my wife asks "What?". I told her Clickspring's clock is running and got an eye roll. Some people just don't understand.
Ha ha! That comment has made my morning. What our wives have to put up with eh?
They sure put up with a lot. Keep up the good videos man, you're amazing!
Your attention to the details is an inspiration to all of us. Thank you.
Wow. Just... wow. Tremendous seeing this come to life after all this time, dedication and story telling.
Cheers Gareth :)
great job my uncle was a clock maker in your country now i know the delicate work he went through and the satisfaction he must of had.
Congrats Chris! This is so awesome
Cheers max!!
Chris, to hear it tick-tock for the first time must have been a very proud moment. It was certainly beautiful to watch. Your work and workmanship is an inspiration. Well done mate.
Cheers Jake!
So cool to finally see the clock run under its own power and to hear it tick for the first time. Awesome work Chris! Can wait to see the clock in its final polished form.
Thank you mate!
Well I've had a crap day in work.....I was angry as all hell breaking loose and knew just what I needed to relax with, many of your videos......great as always and the sound of a running clock brings back memories of both a grand father and mother clocks......long gone now but still relaxing
Terrific to hear that Matt :)
I can't believe it's been almost 2 years since I started watching this clock come to life. Those first clicks were both a milestone for the clock, Chris, and the rest of us who have followed you for all of this journey. I'm excited to see it coming together finally, but almost don't want it to end. You've done an incredible job on this clock, Chris. Your attention to detail and continued patience is something I am very envious of. Keep up the great work!
Cheers Logan, very much appreciate your encouragement and support, its been a long road!
I've been watching you since you began the clock piece. I considered myself a craftsman who works with many mediums. Now I'm an amateur. You are in a league of your own.
I honestly can't even remember how long I have been waiting to see this clock run! Extremely exciting.
That hole punch for the mainspring seems like the roughest you've been with any part of this build. XD
Most well produced videos on UA-cam. Very comforting to watch.
Camera work is always top notch, but it was absolutely stunning on this episode.
That is amazing work. You must be so chuffed to see it working finally,
Thank you mate :)
I've been watching click spring since close to the beginning of this watch, it's amazing to finally see it come together.
I can't believe how excited I was to see it ticking , I can only imagine how you felt! As always thank you so much for bringing this us to watch and share.
Congratulations Chris, This moment has been a long time coming.
I can't believe we saw it run. I have been waiting for this for months. Thanks, and I ca't wait to see the final product.
this is a big moment of the life of the clockmaker ... kudos , loved every single video , very relaxing and satisfying thank you
As an engineer i love seeing this clock take shape and it always amazes me to see the craftsmanship and attention to detail that goes into your work, but this video has really topped them all just to see that hand polished finish on the escapement pallet. It has been a real pleasure seeing this clock come to life and i can't wait to see your future projects!
Congratulations on this milestone, Chris. Watching a new Clickspring video is always a pleasure. I hope you have another project you'll tackle after this clock is finished.
Yes the next project is well into development, looking good so far :)
Absolutely amazing to see the piece finally come to life. Cannot wait to see it with its final polish.
A triumph of precision engineering that was destined to have it's capabilities surpassed in time. Even so the craftsmanship of a simple quartz timepiece will never be so fine a machine to simply admire.
Wow, you sure have a lot of patience with a file, beautiful work as always, Chris!
Hey Chris, your craftsmanship in the manufacture of this timepiece is only exceeded by that of your videography. Your understanding of pre, post, lighting and audio recording and sweetening turns a really interesting project into a beautiful and inspiring piece of art. Many thanks.
Thanks for the encouragement Steve, much appreciated :)
Maybe a vid showing your workflow????
When I first found this series I wished that I found it later so that I could see all episodes at once... now I fear the end of it :/
I really love this video series! Thank you for making it!
I have to be honest, I wasn't a fan of yours at first, but I've become very intrigued and interested in this build process and now can't wait to see each new one.
Been here since the beginning Chris. Congratulations on the first few ticks. Amazing work as always! Cheers!
Yes you have, very much appreciate your continued support mate :)
16:20 "This is a big moment in the life of the clock" THIS is a big moment in my life! and hats off to you Sir!
Great to have you watching mate!
Such amazing craftmanship for a single piece! Amazing!
I have to admit when I first heard it start I teared up a little. I've been waiting for over a year to see this thing in action. What a phenomenal project, great work!
Cheers Stuart, a few man tears were shed on this side of the camera too :)
Hell yeah!!!!!! Its HAppening! Its happening!!!!!!
Extremely impressive series! I will undoubtedly watch the entire series over again. Thanks again Chris for taking the time to document the project with flawless precision!
Cheers mate!
Wonderful craftsmanship, with a great result.
Cheers Randy!
A debt of thanks both to Clickspring and to UA-cam, for enabling me to watch the creation of this work of art.
Great to have you watching Ian :)
Wow, beautiful seeing it coming to life and so delicate too. Such intricate work well done Chris...proud dad I bet ;)
Yes very much so!! Could not stop looking at it for the first few hours, kept sneaking back into the shop to check on it!!
My heart was pounding when chris was winding the clock. Great to see its working
Congratulations Chris. Huge milestone :)
Thanks Jess :)
After watching you do all that work, hearing those first ticks and tocks. Damn, that sounds nice.
just realized that soon this series may be over... Makes me sad, but also i can't wait to see the clock being done! what are you planning to do with this channel once the clock is completely done? Will you build another one?
don't worry, I'm sure he'll do something more awesome next.
I hope.
I think that at the end of the series Chris should present himself and take us on a journey into his shop
Definitely, the next project has got me totally fired up - more details once this one is safely over the line :)
Ohhhh man I'm extremely excited!!!
a good tea, light off, and watching Clickspring with love
It's so great to see it become a living thing finally after so much painstaking work.
You really have made something remarkable and it has been a pleasure to watch you do it.
Terrific to have your support John, thank you :)
How can your comment be from four days ago, when the video is just posted today?
***** Patreons see Chris's videos one week earlier.
wow, nothing is more awesome than that 1st push of the pendulum and watching your mechanism begin ticking.
fan-effin-tastic!
As I've said before, these videos are fascinating! Can't wait to see the final product
This is my favorite series of videos. Very nice surprise to wake up and see it running today.
Amazing work, Chris. Congratulations on a job well done!
Thank you mate!!
It's finally running. So good to see it in action after watching how you make every single part and/or additional tool
Beautiful work as always Chris! Almost therapeutic after watching an AvE video. :P
Beautiful Chris. I'm so appreciative you have shared this project with us all. I hope you celebrated this milestone moment!
Tim
Cheers Tim :)
I actually had a lump in my throat watching it going for the first time. Wow. Good job Chris. Excellent series, and outstanding craftsmanship. Thanks for sharing this process with us.
It feels so great to finally hear the clock tick after years of episode.! Keep it up..!
His "ill see ya later" at the end of each video ita like hah, my computer can load the next video in less than 2 seconds. I'll see ya now please and thank you.
This is still my favorite series of them all, a true masterpiece
Congratulations! I did not think you would do it so fast, getting the drops right is difficult. Specially with a file; there is no way po put filings back on! Clock sounds wonderful.
Thank you Juan, very much appreciate your encouragement :)
I'm so happy to see it run! You must be beyond excited!
AWESOME! I've been here since Part 1!! :D
Appreciate you tuning in for each release, thank you :)
another awesome video! I bet you were smiling like a big kid when you heard it tick, I know we all were just by watching it :)
I understand why you finish with such care and precision. I also really love watching through the entire process. What I was wondering though, is why you give yourself so much extra when rough cutting? Surely burring isn't that bad!
Also congrats! Absolutely beautiful!
I've learned the hard way that its best to be cautious; I hate scrapping parts that require so much prep like these. Its hard to see it because the scale is deceptive, but I generally don't really leave that much on, somewhere between 0.5 and 1mm. At least half of that is unavoidable; its required to make the finishing cuts with hand files. If I leave much less than 0.5mm on, the belt sander or filing machine can easily leave a cut inside that finishing allowance and ruin the part. Acute corners are an exception, I always leave a bit more on in that case because powered cutting in a tight corner is asking for trouble, best to go in gently with files.
I see, thanks! Keep being awesome :)
It was joyous just watching the clock mechanism work for the first time, I can't imagine how it must feel to have made it!
Its been amazing to see this project come to life. By far my favorite series of project videos on the internet!
thanks!
This is simply beautiful. That last shot of the clock ticking away with the wheels crossing each other was gorgeous and masterful.
It will probably be a bittersweet moment when the clock is finally finished. Yes, it means the project is complete, but there is no project to work on for a bit. These videos are the highlight of my day and I am very excited to see if you have plans for a new project.
Definitely more projects on the way, the next one to follow this has got me very excited :)
It always amazes me how much material you leave before you start hand filing. Can I ask how much time you actually spend filing a piece like that to get it to its "rough" shape(the paper lines)?
It depends a lot on the part; the pallets took about a day of tuning to get them where they needed to be before heat treatment. Thanks for watching mate :)
Thanks for the reply. Your videos are very inspiring. My grandfather was a watch and clock repairman at the time when some people would consider that it was a dying trade - he had a lot of business. He was pretty well regarded in the area and had a ton of specialty tools and made parts that were no longer available for purchase from the manufacturers. The tools are now in my possession along with a ton of books on repairs/building clocks and watches. I also acquired about 100kg of random watch/clock parts - thousands of them are in their tiny original packaging. For example I have a drawer full of tiny mainsprings of specific sizes all in their small little casings to ensure they stay coiled. I hope to tinker with the parts and hopefully put something back together one day. I have a lot to learn but your videos definitely get me thinking. Can't wait to see the finished product.
Absolutely stunning! That click is so satisfying to hear! Please start a new project after this, so we can continue to watch these wonderful videos.
Definitely more projects to follow this one, appreciate your encouragement Chad :)
SOOO satisfying!!! Amazing work Chris.
This makes me want to go polish some random metal. Man is this relaxing!
Nice clock, beautifully made. Soon it will be finished. What will you do next?
I bet that your audience will explode if you build a working antikythera mechanism, piece by piece:O It is possible and it has been done before, it would be absolutely insane if someone made a replica with same shine and precision as your clock. in HD!
I dont know if anyone has made this suggestion already but here we go.
Actually a very good idea
Have they even figured out just how many gears the ATK mech was made with yet? Oops, sorry, I will go and look online...
+Knolltop Farms Attack mechas?
Last i read about it, the antikythera mechanism has between 32 to 70something gears (or moving parts).
Yes! A Clickspring Attack Mecha would be awesome! He might have to make some larger heat-treat trays for the parts, LOL!
I too had recently learned they did another series of X-rays on it, and while this enabled them to discern the exact number of teeth, the researchers won't say exactly how many gears it had excepting that "It has at least 30 gears".
Apparently there is much speculation about missing pieces that would calculate the positions of the 5 classic planets...all of which I'm sure you already know, but it is just so fascinating I can't help talking about it. :)
