Constructing A Byzantine Sundial-Calendar - Part 2 (Cutting The Wheels & Pinions)
89,329
Publicado 2024-07-23
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 YouTube 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.

The relief feeling every time the last tooth cut matches up perfectly.

It’s a good day when there is new Click Spring.
-
Between Clickspring and Inheritance Machining, I'm all geared up!
-
How lucky are we that a man with such exceptional engineering and machining skills also has exceptional video production abilities? I feel darn lucky. I could watch Clickspring videos all day long. Thanks!
-
Millions, billions of years and I have the honor of existing in the same lifetime as this wonderful man. Thank you for everything you do
-
Best adult bedtime story series...for a few moments, with a warm glass of fine Brandy in hand, its as if there is peace on the planet.
-
Theres something intensely soothing and mindful about watching a brush applying engineer's blue to a rotating workpiece 😊
-
"Thank you for watching, I'll see you later". No saddest words ever spoken on yt. I could watch this for hours
-
I really appreciate that even though Clickspring is a big time YouTube maker they still think about things like making good use of stock and material waste.
-
30 seconds, that how long it took me to learn something, that using the piece of paper to hold something while using spray adhesive so it doesn't get all over the table or your fingers, brilliant.
-
Easily the most professional , educational and thoroughly enjoyable channel on Youtube , great work Chris !!!!
-
I could watch this Man work all day. The attention to detail, work processes, hints and tips all make it fascinating. Thank you Sir.
-
Been hearing about you in the news due to your work on the Antikythera Fragment congratulations good to see hard work recognized.
-
As a person with aphantasia I really appreciate how you overlay the cad design with the actual parts it really helps to understand how the whole assembly works. It also gives me an added appreciation for how much is actually being done. Your skills in your craft are amazing and I thank you for sharing them!
-
Thank you Chris. Your videos are always enjoyable and informative. With immaculate workmanship.
-
Brilliant, Chris! You really know how to capture the most satisfying moments of every build!
-
It’s weird watching him use modern stuff!
-
I must say ive watched almost all of your videos and you are good. I like how you build your own mount for the motor to cut . You give a very good look at how things are made better then anyone on the internet absolutely amazing Chris
-
Cant believe I made it within the first 10! Always a good day when we get to learn from a man with patience and attn to detail we'll never have :)
