On outside diameters that I can measure to 0.0001" the lathe can shave
a few tenths with a freshly honed bit.

So, turn a "setting standard" that IS the couple of tenths smaller than the
bearing, and use that to feel out your hole as you enlarge it a half-thou
at a time (after boring to a nominal under-sized dimension).
