I have done quite a few engines .010 over with a ridged Sunnen hone. like earlier posted 100 grit roughing stones run dry can true up a cylinder in about 10 minutes. Medium and finishing stones run with oil finish the job in about 30 minutes total. Most shops are going to want to go at least .030 when using a boring bar.
Then largest jobs I have done is taking the C153 in my 2444 from standard to .010 over. I actually had a spot on one cylinder about the size of a penny did not clean up completely. I left it because it left more material for a future overhaul. I also took a Ford 391 from .040 to 060 over. The most time consuming was on Continental engine in a Massey Harris 101 Sr.
It was a patch job with a vertical crack in one cylinder. It was at 030 and I took it .125 over and pressed in a repair sleeve. I then took the repair sleeve back to standard since I needed a piston and the customer had some extra standard pistons. That job provided the iron powder that I used with my Magna Flux equipment for many years.
