Constructing A Byzantine Sundial-Calendar - Part 1 (Making The Cutters)

[@Calymos]

So... what is the skill pathway to this? Say you just finished high school and are interested in learning how to do stuff like this, or horological crafting in general- what do you need to learn and know?

[@Clickspring]

Books are a great place to start (Daniels' Watchmaking, JM Wilds' Wheel& Pinion Cutting, DeCarle's Practical Watch Repairing). There is an excellent distance learning courses from the BHI: bhi.co.uk/training-education/dlc/ Also of course, watchmaking school if you have one in your area - Cheers :)

[@Calymos]

@@Clickspring thank you so much!

i did a pre-apprenticeship course at Ballarat University in 2011, 6 month course, 3 days a week full time, split between welding and machine shop (lathes, milling machines etc). i highly recommend such a course, especially for younger people, there is a LOT of money to be made as a welder or maintenance fitter. i was a mature age student and had not touched a lathe since technical school in 1982/83, now at 57 and disabled it was so i can work on my old cars.

@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!

[@andersjjensen]

I think he gets his reward simply from doing it. Not to mention that basically all the "proper" machining channels on KZbin 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.

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: www.patreon.com/clickspring/about Those of you who are Patrons will notice that for this KZbin 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.

[@Senki207]

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!

Chris, you should put this series all together in one video. It would be the best documentary on this device. You truly are a master and an artist.

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.

[@drmilkweed]

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!

[@Clickspring]

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: kzbin.info/www/bejne/g5yumJenapyohdE )

[@wobblysauce]

It is one of thoese things, dont need to know it but it is nice to.

[@khag.]

The article I just read quotes Woan saying the inspiration for their paper was this KZbin channel!

[@Batfunk1]

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!

[@mulletthehunter7163]

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

Its phase of the moon. It used to be a common enough wording in my part of the world.

*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.

[@NathanaelNewton]

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.

[@Shelleloch]

​​@@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".

[@FrozenThai]

​@@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

[@andersjjensen]

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.

[@piccalillipit9211]

@@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.
