If you gave them a lathe, I wonder what they would have made. That confused me because in Spanish, the same word is used for a potter's wheel. Anyway that would be more recent too. But I think that there's a long prehistoric period, between stone tools and stone buildings, that we know very little because they used wood, more than anything else. I have a lot of respect for our far ancestors thanks to this guy: https://en.wikipedia.org/wiki/Miguel_de_la_Quadra-Salcedo https://en.wikipedia.org/wiki/Miguel_de_la_Quadra-Salcedo He made some awesome documentaries in the 70's showing stone age tribes in the Amazonia and their incredible techniques to make a blowgun, arrows or a hut. It seems there's much interest here for CNC, did you see this post? https://news.ycombinator.com/item?id=39141816 https://news.ycombinator.com/item?id=39141816
