Confession time: How It’s Made is one of our favorite shows. Especially the car stuff. We aren’t that into seeing decorative candles coming to life, but car stuff–that’s destination TV.

Anyhow, we found this clip from the show online of billet pistons being made all the way from cutting blanks from billet to final cleaning. Watching the video won’t instantly put you on your way to manufacturing your own pistons (Wouldn’t that be cool?) but it is a fascinating watch.
