Neat idea, but I gotta ask...does the light down below collect any
dust from the drilling or does a vacuum pretty much
take care of that.

Rick,
I think you misinterpreted the arrangement. The drilling is down from the
top, but the light is shining up through the bottom of the board. The
board is placed on top of the project box which has the laser pinhole
setup. I use the Eagle drill-aid.ulp which provides a smaller etched hole
than the regular hole. The board is positioned (looking down on the
board) so that when light appears in a hole that is where the drill will
penetrate. This has improved my depth perception so that now I can pretty
much drill a straight line of holes.
