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

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 KZfaq 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!

@Clickspring 2 күн бұрын

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: kzfaq.info/get/bejne/g9F7mseimp3Zf6M.html )

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

*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.

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.
