The Antikythera Mechanism Episode 9 - Making The Epicyclic Pin and Slot Gearing
In this video I make what is arguably the most impressive section of the mechanism - the small gearing module that models Hipparchos' observation of the variable motion of the moon.
In this video I make the gearing that calculates the mean sidereal period of the #dearMoon , and have a closer look at some of the mechanical limitations of the device - Please enjoy :)
There are several components in the mechanism that were carefully soldered into position - here's my take on how it may have been done - please enjoy :)
In this video I make the gearing that drives the eclipse prediction function of the mechanism. Be sure to check out the reference links in the description box for more info on the Saros cycle, and other eclipse related stuff.
This video was done as a one-off viewer request but I like the format so I'm going to keep it going as a request driven series. Let me know in the YT comments if there is anything you want to see covered.
The precision of the holes in the Antikythera mechanism is one of the most fascinating aspects of its construction. In these 2 videos I make a tool that is capable of creating holes to the required standard, yet is consistent with the level of technology known to have existed in the period.
In this video I make the gearing that drives the Metonic, Callippic and Olympiad pointers. If you're interested in a bit more detail on the ancient Greek approach to calendars, then I recommend this excellent article on the Athenian calendars - https://www.ancient.eu/article/833/the-athenian-calendar/
In this video I make the small assembly that enables the user to drive the mechanism. Its an extra length episode for you folks, so please enjoy!
In this video, the most recognizable component of the mechanism continues to take shape, and becomes the first moving part within the plates. Please enjoy!
Antikythera Fragments #3 & #4 - Making & Case Hardening A Set Of Hand Cut Precision Files For The Antikythera Mechanism
One of the key tool technologies that needs to be explored around the Antikythera mechanism is the simple hand held file. So in these 2 Fragment videos I investigate the traditional processes used to make files in Antiquity. From hand cutting the teeth with a purpose made chisel, to hardening the file cutting surfaces using the original case hardening process. I have used materials consistent with the period, and reproduced the methods as close as I can get them to those practiced thousands of years ago.
