2000 grit is too fine for finishing a crank journal. Crocus cloth is 320 grit and leaves the journal with a little bit of "tooth" which helps the needles roll, not slide. Rotating the crank while polishing is a good idea and a good way to get a nice even finish all the way around. Turn the crank slowly. In a lathe, maybe get someone else to hand-turn the lathe while you polish. My experience has been that a nice guy in an automotive oriented machine shop will probably give you a length of crocus cloth if you ask. Maybe trade him a 6-pack for it.
