Complex parts with humble tooling

I thought this video of a crankshaft being manufactured using regular lathes and such was interesting

I always wondered how they did that back in the day. I'm sure they don't do it that way at GM anymore. Probably something like this. Click on the video and it will go to youtube.

I just about laughed when I saw the large steel bar they started out with.  No casting for us!  Amazing.
I think GM is still concerned about cycle time and minimizing chips. :-)

It amazed me how easy it looked to cut, like it was plastic.

They  still  use both ways  to make  crank shafts  one is cast and one  is forged. If I'm remembering  correctly  the one  in the  2nd video  is forged for  more strength  for performance vehicles
