If you had a crankshaft that was slightly below the wear limit on the mains, rather than regrinding it one size under, would it make sense to just polish it, buy a set of standard bearings and send them to calico for coating a dry lubricating film inside the bearings with enough thickness to bring the tolerances back into specs? I am pretty sure they can coat any thickness we ask, not sure what the maximum is. Just a thought...then if you had spun a rod bearing, do the same on a new rod bearing...I wonder if this has been tried before.
