I find myself having to enlarge a bushing's ID by 1/16ths to 3/8ths.
My concern is I don't know how to insure the 3/8" bit is aligned with
the axis of the hole. Centered is good, but I'm more concerned with
the alignment.
Suggestions? - Mike

Chuck a rod in the drillpress the same size as the existing hole. Slip the
bushing on the rod and clamp it to the table. Replace the rod with your new
drill or reamer. Make shavings.
