Paleotechnology

I have always wondered about how people accomplished the things they did, when they were done for the first time, like: How do you make a metal chisel, when you don't have the metal chisel to chip out the metal ores that you need to make it? How do you make ball bearings before you have the smooth axial motion that they alone give?

I'm hoping to make this blog a record of various things that I've tried in an effort to recreate certain early technologies.
