Default Moving center drilled hole

Say you've laid out the end of a shaft for a center hole
to take a dead center and the hole comes out a bit off
center. How would you go about 'moving' the hole
back to center?

My favorite hole moving tool is a block of metal (steel preferred,
depends on what you have and the material you're moving the hole in) and a
gun barrel drill bit. Drill the hole in the guide block and attach that to
your material. It's essentially a drill bushing. A gun barrel drill (IIRC,
it's been awhile) only cuts on the face, so will cut without wanting to pull
off center too much.
