Goldhunter_2,
It's become apparent that advice from those wiser than you will not detour you from your thought of using a lathe for a crankshaft grinder. Just for starters, the bearings in the head of your lathe do not have the integrity plus your tailstock is static versus being powered and synchronized with the head.
Wakeup, take a break from your wet dream, go to an engine rebuilding shop and request permission to watch while they setup and grind a crankshaft. If that does not enlighten you then you'll just have to learn the hard way.
The value of the time you spend trying to convert your lathe to a crankshaft grinder plus all of the crankshafts that you will screwup will make the price of a used crankshaft grinder seem very reasonable.
This advice is coming from a person who has many years of experience wih crankshaft reconditioning (Ran grind shop for Swick-Guth, a company that was a Caterpillar certified engine rebuilder (2 cylinder starter engines to D12 engines) prior to Caterpillar doing their own rebuilding) and many more years of lathe experience (Boeing Military Aircraft, CertainTeed plastics tool and die division, Cincinnati Milacron........)
In summary, You're peeing in the breeze and looking like a fool with the pee dripping off of your ears.
