This with a Van Norman bar.
I remember cutting about .030 at a pass, sort of max.
Make the last cut a light one, maybe .010. This will keep a straighter bore.
Hand honing, with a good sharp boring bar bit, You hone .001 pretty easily... Leave about .002 so you can get to a solid surface for the rings to seat on.
