Antikythera How The First Precision Drill Bit Was Made?

Antikythera Fragment #5 - The First Precision Drill Bit, by Clickspring. There are a number of cutting tools implied in the wreckage of the Antikythera Mechanism, and one of the most interesting is the drill bit. In this video I explore a possible method of how an effective and precise drill bit could have been made in antiquity. The video where I show the carburisation process in detail can be found here: https://youtu.be/V_Mp1fNzIT8 If you would like to help support the creation of these videos, then head on over to the Clickspring Patreon page: https://www.patreon.com/clickspring ________________________________________________________ A very special thank you to Patrons: Sinking Valley Woodworks (http://www.sinkingvalleywoodworks.com) Glenn Trewitt Christopher Warnock Mike Manfrin Steven Sladewski Rollin W.
