Entertaining dive into hands-on-wrench, nitty-gritty tangible reality where this guy seems to have gone a bit out of his head over some flat washers. He starts out with a pair of calipers, progresses to 2 types of micrometer, and even tries his hand at probing them with an analog tool with dials.

Rarely submit to HN, but I regularly enjoy content created by lots of interesting-but-virtually-unknown people and today seemed like the day to try to do my part to help at least one of them find a bigger audience.
