What Tony said ! .
I have never tried my hand at being a machinist , nor have I yet to meet an Machinist . no matter how competent , who's a good Mechanic .
Odd but true .
Seeing a crankshaft whirling off centered on the lath , is amazing as it appears ready to fly off and kill someone at any moment .
Then , there's knowing how to properly radius the corners in the bearing journals , failure to do this the specific way necessary on older Air Cooled Porsche cranks (a , B & C) , has caused many to develop cracks and fail rapidly .
All in all I know so very little but I'm always enjoying learning new things .
I'm about to head home and begin tinkering on my Coupe , folks keep coming up and telling me I left the lights on it my old truck , not realizing my seasonal illuminated Christmas Wreath , stays on until the sun gets too bright .

> Turning the journals is not that hard, the crankshaft is being cut out of a solid piece, so you make a fixture, or use a four jaw chuck, to hold the piece with the journal centered, at the chuck, and either a similar fixture or just a spot for a live center at the tailstock. The workpiece spins way off center except for the journal being turned.
> PS knowing how it is done, and being able to do it are not the same.
