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.

> After repeated copying and correction, Maudslay made a master screw five feet long and two inches across, with fifty threads to the inch and a foot-long nut that engaged six hundred of them at once.

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.

Good work! Your style of animated articles reminds me of the work of Bartosz Ciechanowski: https://ciechanow.ski/archives/ , https://news.ycombinator.com/from?site=ciechanow.ski

I've sometimes thought of making a YouTube series where the foundations of precision are created as increasingly precise artifacts, building on each other and following the history. Something like the "Primitive Technology" channel but for machine tools.

how did you make these videos? ive struggled to understand mechanical systems from static figures and these are super helpful
