If you have a lathe or access to one it's simple. Just chuck the
bushing in the lathe with the drill bit mounted on the right side...
can't think of the name of that part..

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
