Dennis,
I can do OK with just top light and about 0.01" of clearance between board
and drill during positioning. But it would take less concentration if I
added a means of locating the touchdown point. Maybe a thin clear plastic
plate would do the trick. I would just attach an L shaped piece and then let
the drill make the hole so it would be self aligning. Hmmm.

Rick,
Recently I did this. I cannot tell you that it was a terrific improvement.
In my arrangement there are overhead lamps as well as the one below the
deck. I am still experimenting but this probably would have worked better if
the overhead lamps were dimmed a little more and the copper was not as
reflective, maybe cleaning the board before drilling isn't the way to do it.
The led I used was not specified, just claimed to be super bright white,
4.5v. I am running it at about 30ma., as much as I dare.
