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.

Armchair metrologist here. Did metalworkers back then use 16ths, or 12ths and 24ths? I'm familiar with the use of 1/12th lines ''' and multiples of 1/144th points ''''.

Good question! From my reading, English engineering shops like these used 1/8ths and 1/16ths. Whitworth did push for "decimal inches" (1/10, 1/100, etc). It seems like the 1/12th and 1/144th were more common in watchmaking and optics.

Interesting that many of the early steam mills used a steam engine to pump water into a water tower, which then drove a conventional water wheel to power the millworks.

How was AI used when writing the article? Not implying anything, I haven't started reading it (yet).

Certainly a fair question!
The text was hand written, but reviewed by AI and light edits were made. The CAD models that drive a lot of the animations were either sourced or built based on pictures of historical machines. As called out in the credits, the interactive figures were built by myself and Claude Fable 5 (mostly - a bit of Opus 5.5 in there now).
The article itself was built over about 4 months.

> 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.
