- Author here. This is a sequel to my beam engine article: https://glinscott.github.io/beam-engine/.
I started digging into Watt's challenges getting an accurate cylinder bore for his pistons, and it spiraled out from there :).
The article covers some of the key techniques developed during the industrial revolution to measure and make incredibly precise parts. There are a lot of animations and interactive figures to explore how it works.

That's the stuff I like to read about the historical endeavors. A fifty-threads nut doesn't average the distance between the grooves quite accurately enough? Then let's make a nut with six-hundred threads on it, and so what if it's foot long.
