I've been following Chris for ages and have always been impressed with his skills related to clockmaking and to a lesser extent, watchmaking.

His latest update is centred on tools he hand made in the ancient methodology to construct an Antikythera machine as they would have done two thousand years ago.

Enjoy it.

 

Interesting - He places the tool below the rotary axis (longitudinal turning).

 

Cool! There's a really fun NOVA episode about the antikythera mechanism.
