Okay - this sounded too easy so I decided to try it. I found a piece of 1/8" x 1" aluminum bar stock. I drilled an .020 hole in one end of it and drilled and tapped a hole for the 00-90 screw in the other end. I cut off a piece of the .020 end about an inch long and a piece of the other end about 3" long (dimensions are unimportant). I stuck a piece of .020 wire through the small hole and then a piece of Teflon tubing from a CA extension cap over the wire. This Teflon tubing was just the right size to fit through the tapped hole and acted as a centering device. I glued the 2 pieces of aluminum together with 5 minute epoxy while the Teflon and wire were in the holes.
When the epoxy had set I put a screw all the way into the tapped hole and ran a drill in the other side. I got a nicely centered hole on the first try.

Thanks John. I've done several freehand but it's not a lot of fun.
What I was thinking of is maybe a sandwich of 2 sheets of metal. One would have a threaded hole for the screw and the other would have a guide hole for the drill bit. The 2 pieces could be lined up and glued together with epoxy or CA. Then you could just screw in a screw on one side and put the drill in the other side and "let 'er rip".

Ya didn't ask, but here's how I do that task anyway:
- I use that cheap Dremel drillpress thing to hold a Dremel with
a .013" drill bit in it (it's a nice bit - the shank flares out to fit
the largest Dremel chuck)
- The nylon screw is screwed into a threaded hole in a flat piece of
scrap plastic
- I line it up by eye and let 'er rip
Despite the relative kluge-iness of the whole thing it is pretty easy
to do and the hole gets pretty dang centered and lined up
