I can't find the Sumitomo inserts they suggested but I'm hoping my CDCD-505-CBN1's will work for my small boring bar. These are not for interupted cuts so will take light passes.

I would have liked seeing one more cut and measurement after the jaws were ground. He figured he was within 7 tenths across the length of the bar before cutting the jaws. The 1 jaw was larger than the other 2, looked liked he could have corrected for a couple tenths at least.

Good info but the video could have been shorter with less talking, more showing
I would also have liked to see a before and after the chuck jaw procedure, I don't recall if he said how much runout it had to start with
