Constructing A Byzantine Sundial-Calendar - Part 1 (Making The Cutters)
ฝัง
- เผยแพร่เมื่อ 27 มิ.ย. 2024
- Hey Folks,
Designed and constructed in 2016-2019 as a companion project to the Antikythera mechanism, this video series is an alternative look at the second oldest geared mechanism from antiquity: The Byzantine (London) Sundial-Calendar.
I designed the project as a sort of 'gateway' project into more complex horological work, especially if you're already comfortable with model engineering, and maybe feel like tackling something a little unusual. I've seen some outstanding builds of this project over the intervening years and would love to see more. So, if you'd like to build along with the series and help me make these videos, the plans for the project are available as part of the $1 tier on Patreon, find out more here: / about
Those of you who are Patrons will notice that for this TH-cam release of the series I've spruced up the intro card and soundtrack, and also combined a few episodes together to make it all a bit more efficient for the viewer. For those who are seeing this narrated build series for the first time, do please enjoy!
Cheers.
Chris.

did you see the news that the antikythera mechanism calendar ring was very likely to have 354 holes? soon as I saw it I checked your channel and caught a new upload pretty early on!
Yes its been great to see the most recent research on this :)
(edit - for those following the research, two new studies published in the peer reviewed Horological Journal from Woan & Bayley bit.ly/3W25FZN and separately, Malin & Dickens bit.ly/3XDbjTl confirm the finding that the calendar ring divisions of the Antikythera mechanism are most likely 354. I will cover the implications of this finding in future Antikythera videos, but you can learn more about the finding itself here: th-cam.com/video/MkKgdq57uOo/w-d-xo.html )
It is one of thoese things, dont need to know it but it is nice to.
@clickspring “I know, in my spare time, for no reward, I think I’ll outdo the British Museum. And do it brilliantly. And film it like poetry.” What a star, Chris!
I think he gets his reward simply from doing it. Not to mention that basically all the "proper" machining channels on TH-cam distinguish between "an acceptable finish" and "a Clickspring finish". The latter being considered neigh on unobtainable and/or complete overkill for the sake of overkill.
@@andersjjensenmore than neighs I've heard it as praise for Chris of the flush finish he's able to get
@@swaree Yes, if you are a God, then let it be so.

CLICKSPRING IS HERE, DROP EVERYTHING!!!
Hey, Chris! Great video as always, and the timing couldn't be better. Five years ago, it was watching your skeleton clock series that gave me the idea that maybe I should get a second degree after applied linguistics, this time in mechanical engineering.
In less than 10 hours, I'll be attending my graduation ceremony as a future mechanical engineer. Keep making these videos; no matter how big or small, they're having an impact. Cheers mate, from a far corner of the world!
Congratulations mate, well done!
The absolute joy that comes with a clickspring upload notifcation is only bettered by the video itself! Time to put the kettle on and enjoy youtubes best content!
I am a 75 Year old knowledgeable educated electrician, what knows stuff. Or...At least I thought I did. Thank You world, for our Clicksprings. They warm our cockles and amaze us.
"...who is knowledgeable"
"what knows stuff." is a dead giveaway 🤫
While watching this I was thinking about my apprenticeship back in the late 1960s and wishing that Clickspring had been one of my instructors.
Clickspring is the GOAT.
Disciplined on many levels. Cinema magic achieved with a very modest toolset and a commendable focus for research. Followed with the heart of an innovative teacher. 👍
I'm glad Zurich made it onto the Dial... and I can confirm it is currently sunny here :)
As a Patreon Member I love the opportunity to see this series again and slightly reimagined to boot! Thanks Chris!
The brilliant genius known as Clickspring is in the building with a new video!
I only subscribed earlier today and I’m treated to a rare episode on my first day 😮
Oh boy do you have a good back-catalogue to go through!
A tip for mental health, though: If you ever try to polish something... forget that you've ever watched Clickspring. Just go "I think this looks pretty!" instead.
i love your amazing skills
i love the way that you narrate the things you do
this is one of the best channels to have ever been om youtube!, Pure class"!"!!
SOHCAHTOA
That took me right back to the classroom.
Me too - it took a moment to remember what it referred to
What a marvelous device and project. Knowing your skill, this will be surely be captivating to watch. And educational, as well :D
Thanks Clickspring.
Chris is the hero we all need!
Really?
Happy to see more new video's lately, Thanks Chris!
I watch your videos to live vicariously as a smart person.
An absolute genius. I am simply in awe. Outstanding!!!
Thank you for continuing your projects!!!
Woohoo! Always a good day when a new Clickspring video comes out!
Just amazing! Chris, thanks for the video and your explanation, helps a lot!
Awesome videos. Thank you for sharing.
Legend mate, thanks for the explanation. awesome work!!
As ever just jaw dropping brilliance!
I’m looking forward to the Clickspring Flux Capacitor series
Im in awe. Truly.
Well done mate. great study for all. thank you for that.
outstanding vid as always
You remind me of Steve Erwin in a good way. Never stop making videos, man :)
I didn’t expect that rather thin cutting surface going thru the brass plate in one pass. Color me shocked.
Chris! I love this series, keep it up friend 👏
So happy I get to see this day
great work !!
Last week I watched the entire Antikythera and Skeleton clock projects, then went on patreon to watch the gauge. Yesterday I got so excited before seeing the notification was a clickspring clips one. Now I got another sad face, but guess I'll watch the last patreon series all the way through over the weekend
Love this guy
Yes, yes, yes! Thank you.
Nice work Chris!
Amazing
That's pretty cool
Amazing!.
i have a serious complaint ... your videos are not long enough as i enjoy them too much thank you
I recently moved to Hermosillo, Mexico, and the local university unveilled a large scale antikythera mechanism a few months ago, wonder if they used your research
I really enjoy these videos! Your voice is so lovely to listen to and the projects are fascinating and educational! But one thing I'm loveing, is the music! Could you post the music you use?
New compilation of series from 3 years ago ? A bit of a dejà-vu but still nice
Hilariously, there's at least one Chinese company making wrist sundials for drop shipping and I kinda want one just for the ridiculousness of the idea.
The earliest known pocket watch? Quite possibly.
THE GOAT
Chris I think I've watched all of your videos which are an absolute joy. However I'm not sure I can recall you mentioning how you get the exact spacing on a gear or dial faceplate without getting to the last one and realising you've cocked it up. Would be really interesting to know. Thanks
I'm still on adds but I already liked it, cause I know it's gonna be gooood!
Babe wake up... Clickspring uploaded
Such an incredible build.
Brother you might as well have just explained fucking alchemy to my dumb ass out here. Man just out here demonstrating how math just never even arrived in my mind.
Yay second!!!
You are a different kind of human sir
😎✌
Is this series a re-edited version of the Patron release?
For the algorithm.
Yay first!!!
*I LIVE ON UNEQUAL TEMPORAL TIME...!!!* I get up at sunrise every single day and go to bet as sun set and everything in my day is X hours after I get up
so my 1st dog walk is 1h30 then 2nd is 3h etc. So the TIME as you would see it changes every day throughout the year. But to ME sunrise is an absolute fixed time and yo are very very WEIRD people who get up at a different time every day. It took me about 18 months before I totally adjusted but now I KNOW I get up every day at the same time and the days feel about the same length
Im a self-employed author so I did it for an experiment but I will never go back, your mechanical time is EXTREMELY unnatural - human minds are calabrated by the sunrise - it really messes you up the sunrise being at a different time for you ever day.
How close do you live to the equator? I wonder how this would affect you at a farther north latitude where the daylight length there is considerably throughout the year.
@@NathanaelNewtonI can't imagine it would be much fun living anywhere near the Arctic circle...
They probably live further south than the UK at least, where the sunrise isn't painfully late in the "winter".
@@NathanaelNewton I still live far from the top, but even in winter Oslo, I go to work and leave when it's dark outside (8-16). The sun is up for like 6 hours
That's a nice theory you have there... But here in Denmark sunrise shifts by 5 hours and ~15 minutes between summer and winter solstice. That means you get 6.5 hours of sleep at summer solstice and 17.5 hours of sleep at winter solstice.
@@NathanaelNewton I live at 41N - I appreciate this is not a thing you could do in Scotland. Even then in the depths of winter, I have to stay up past the sunset a little. Its not the sunset that seems to be important for humans, but the sunrise.
Im sorry, "age … of the moon"? I'm uncertain what this means.
I'm guessing that means the phase of the moon, waning and waxing 🌔
Its phase of the moon. It used to be a common enough wording in my part of the world.
Age of the moon: The elapsed time, usually expressed in days, since the last new moon.
-- _American Practical Navigator,_ aka, _Bowditch_
The average length of a lunar (synodical) month is 29 days, 12 hours, 44 minutes, 2.8 seconds. It's generally just considered to be 29½ days.
-- ibid.
„takes concentration to get correct“
aaand I‘m out 😅
When Clickspring says it takes concentration to get correct I hear that as "Prepare for 50 practice runs both mentally and materially".
Yay second!!!
