Got a lathe? Failing that, you could lay the thing out by hand, carefully
centerpunch it, then put it in a drill press. I'm sure you already know
this, but with care, you'd be amazed at how precise you can be on *one*
small part. Especially if it is the second or third one you've attempted to
make. ;-)

I need to make a specialized tool and am looking for a way to drill a 1/16"
hole EXACTLY in the center of the end of a piece of say 1/2" of 3/4" solid
aluminum rod. In other words, I am trying to make something similar to a
screwdriver using solid aluminum rod for the handle and 1/16" brass rod as
the blade.
