==========================
The machinest that does machine work on blocks/heads/cranks/rods/nicked cam journal etc on motors i am building says Crocus cloth is whats best for hand polishing things like a bearing race and or to hand polish journals on a crankshaft like i have done many times over the yrs with great results each time.
Crocus cloth is avail a good hardware stores but the 400 emery cloth (maybe even 600 too) could be rough enough to damage the bearing race if over done or too much pressure is used which is harder to do with the milder less aggressive crocus cloth.
