In a world where the things we build often include several lines of code, I am awestruck by the mechanics of how stuff is made. Engines, which are almost as as plentiful as people, are complicated. And despite the grease and the sweat, there are still people who know how to fix them.
Watch “Goodoldluke” as he strips down and rebuilds an engine he bought from eBay for his Triumph Spitfire. I wouldn’t say he makes it look easy, but it’s definitely pretty.
