I found the experts here and their discussions on the subject very interesting. My plan is that when I finally need to retire either my truck and Corolla, I’ll retain the crankshafts and install them in my living quarters as a reminder of all the fun places they took me. > [@How to manufacture a crankshaft?](https://community.cartalk.com/t/how-to-manufacture-a-crankshaft/76977): > > If you think about it, crankshafts are really treated badly. I mean – along with the heat – the forces they must endure are pretty extreme. So I wonder: How they are made? I guess if I was going to make one myself, I’d use a casting technique. I’d make a mold, pour in the metal, then fine tune the surface and dimensions with machining, followed by case hardening. But it seems like some kind of forging technique might be better. I’m not even sure a cast crank shaft could even stand up th… --- _[View the full topic](https://community.cartalk.com/t/whose-engines-have-forged-crankshafts/110114)._
