This is truly amazing, and something for the machinists and gearheads out there! A man built, from scratch, a complete working scale model of a V-12 engine. And I mean complete.

While the video is in Spanish, you can watch him machine each and every component of the engine, down to the tiny pistons. And then he turns it on and lets it run.

Talk about a steady hand! Check out the video, you won't believe the precision that he achieves.
