Of course I may have not understood the question but here is how I
would do it. And have done it! We put a 1/4 keyway in a 1" diameter
shaft 20' long using this method.

If you have a tube with a hole drilled in it radially, and want to
drill more holes exactly in-line with the existing hole, how would you
do this on a drill press? Finding the center of the tube is the easy
part, but how do you know you have the tube "clocked" correctly on the
V-block?
