Reconstructing The Antikythera Mechanism, by Clickspring A video series documenting the reconstruction of The Antikythera Mechanism in its most authentic form to date, with the intention of establishing the precise machining tools, techniques and technology used to create it.

The Antikythera Mechanism Episode 1 — Greeks, Clocks and Rockets.

The Antikythera Mechanism Episode 1 — Greeks, Clocks and Rockets, by Clickspring. In this first episode of the Antikythera Mechanism project, I lay out the plan for how I intend to proceed with the reproduction.

The Antikythera Mechanism Episode 2 — The Main Solar Drive Wheel B1.

There are more than a few surprises hidden in the wreckage of this iconic part.

The Antikythera Mechanism Episode 3 — The Plates And Main Bearing.

In this episode the basic structure of the mechanism comes together, and I put forward a theory on a simple method for achieving the extremely close clearances observed in the original device.

The Antikythera Mechanism Episode 4 — Making And Fitting B2

In this video the most recognizable component of the mechanism continues to take shape, and becomes the first moving part within the plates.

The Antikythera Mechanism Episode 5 — The Input Crown Wheel Assembly

In this video I make the small assembly that enables the user to drive the mechanism.

The Antikythera Mechanism Episode 6 — Making The Metonic Calendar Train

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/

The Antikythera Mechanism Episode 7 — Making The Saros & Exeligmos Train

In this video I make the gearing that drives the eclipse prediction function of the mechanism. Be sure to check out the reference links below for more info on the Saros cycle, and other eclipse related stuff. [EDIT: At 2:57 there is a typo — the final number in the denominator of the upper expression should be a 30 as per the sketch rather than 90 — Cheers 🙂 ]

The Antikythera Mechanism Episode 8 — Making The Mean Lunar Sidereal Train

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. Be sure to check out the related soldering video here: https://youtu.be/T_MdxdGr57k

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 pin-and-slot module that models the Ancient Greek theory of the variable motion of the #dearMoon.
