How did you "polish off " .002?
That is a lot of material if all you did was "polish" the bearing journal with a piece of fine emery in your hand, or a scotch brite pad.
Now if you chucked it in the lathe, it would a bit easier to knock off a tho' either side.
is the bearing an "easy fit" on the journal, or is it sloppy?
if it is an easy fit, I'd go with it using Loctite cylindrical bond, at this point you have nothing to loose.
Either it is going to be ok, or you are going to need a good used crank.
Are the bearings used? if so, try new ones.
Also are you measuring the crank and bearings both at the same temps? just asking because ewe is in MT. and it gets kkkkkkold there
and if the crank is cold and da berrins is warm, ya gonna see more slop that ya actually got.
And shaft chroming, or spray welding is going to be cost prohibitive.
