Ancient precision


Get interesting at 23 minutes in.
No one seems to be able to demonstrate how one can make a corundum vase to high precision and drill handle holes through it or make a dish out of granite so thin it's kind of transparent with copper chisels, wooden hammers and stone pounding blocks.

As soon as I saw the thread title I thought Seraphium and the Schist disk.

I'm only 38 minutes in but I am being driven from the house by the need for groceries. My theory for the control they had over surfaces is Electrical Discharge Machining.

edit:

Precise orbit from antiquity? At 13:30 he mentions the precision machining.

Clickspring is awesome. It makes you appreciate being able to pick up inexpensive tools at Harbor Freight.

His pneumatic fire starter is interesting.
