Turns out early mills were around some 30 years or so before that so perhaps that 1860 to 1890 and the process of machining was really in evolution on conjunction with metallurgy to provide some steels for cutting and others for products.

I guess "W-group" tool steel was the first. I wonder if they even really knew why it was harder. Perhaps all they knew was "some ores produced harder steel" and they could use that for cutting softer steel. Then "high speed" steel in the 1910s really opened things up, and carbide in the 50s.

Colt was a pioneer in machining tools and tooling. Most of the machines were produced in Hartford and exported throughout the world. Here are some of the early Colt's machines produced in Colt's armories. Most of the black powder revolvers were produced on those type of machinery.

For those who would like to know more here is interesting article from 1857 describing Colt's armory at that time.

Enjoy!
