Hi Folks,
Wine, wax, woad and yes, There Will Be Blood... all in an effort to discover the best ancient marking fluid. (And I'll let you decide how the blood supply issue might have been dealt with in the ancient shop - I'm guessing it might not have been much fun being the apprentice on the day the large dial was marked out!)
Please enjoy,
Chris.

Hi Folks,
In this video I make what is arguably the most impressive section of the mechanism - the small gearing module that models Hipparchus' observation of the variable motion of the Moon - Please enjoy :)

The pin and slot mechanism in progress (short movie) - The pin moves from one end of the slot to the other throughout the full rotation. This effectively superimposes a quasi sinusoidal variation upon the mean sidereal rate of the moon, and was the ancient Greek way of modeling the slight rate variation that we now know to be due to its elliptic...

Hey Folks,
This video is a sort of continuation from TGT#4 where I covered the basic starting point for setting up the shop. In this video I continue the story, with some of the things to consider when selecting a first lathe - Be sure to add your own essential lathe criteria in the comments below.
Cheers,
Chris.

Hey Folks,
The precision of the holes in the Antikythera mechanism is one of the most fascinating aspects of its construction. In this video 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.
Plans for the tool can be downloaded as a zip file here (11Mb): 2018-02-20 06:54:57 +0000 UTC View Post
Hey Folks,
Here is the first of 2 new Fragments videos, both investigating the drilling technology that could potentially have been used to build the Antikythera Mechanism. In this one, I have a good look at a plausible method for creating an ancient equivalent to drill rod, and then shape it into a useful drill bit.
The next one is the main video on the drilling tool, and it should be finished uploading in approx 24 hours.

Hey Folks,
In this video I depth & plant the gear train, and give it all a first test within the body of the mechanism. Its a key milestone in the project, and is a sort of plateau in the build process, verifying much of the previous work. There is of course still a lot of work to be done, but the finish line is in sight!
Thank you all so much for your support this year folks. You keep the lights on at Clickspring, and I very much app...

Hey Folks,
I partially covered this subject in a text article on buying a lathe a few years ago, but I think I can do a better job of covering the subject again in this video, and a few subsequent TGT episodes. So think of this one as a sort of overview if you like, on getting started on setting up the shop, and then I'll cover all of the specifics like what to look for in a lathe, mill etc in subsequent videos.
