Oh, we have the tooling to cut a long hole, called a gun drill. You see,
the problem is that lubrication for the drill comes out of the tip of
the drill, under high pressure. So whaddya think happens when the drill
breaks out of the end?

Uh, it goes all over h*ll and back? What'd'I win? g

Really, what is the problem with that?

I would also think that you could mark the depth on the drill, so it does
not quite break through. Drill the rest without lube, or finish from the
other side, or cut a small length off the end. You will need to have a
small flat part on the end of the prop to mount the lamp fixture on, anyway.
