Castelated holes do not line up

The next time you want to torque up and the castelated holes don't line up just right, just work the flat of the nut down a few thou on a piece of 180 grit wet and dry paper using apiece of heavy glass or a micro-flat to keep the nut surface square. You work it down a couple thou then check to see if you can get the torque spec and the hole lined up, if not, do it again. It sounds like using a lathe would be easier but it really more difficult as you must take it in a and out of the chuck several times to get it just right on the mark. Maybe sounds dumbbell, but, its works.
