Homebrew PCBs

Baxter,

Thanks for the correction. The only difference in our approaches seems to be
that yours works. I tried the high intensity LED yesterday and it was too
weak. If I turned the lights off, I could see the dot of light but not the
drill or surrounding circuit board. I can see how the laser solves those
problems. 

I put my drill press rather high and sat on a low chair so my eyes are about
even with the pull handle. How do you sit so you can see the action?

Rick

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.
