Cool,

If I can find some small drill bits tomorrow, I will try to drill
the holes and solder them up tomorrow. The smallest drill bit I
have on hand is .062" (2mm), and that is too big for these two
circuit boards.

I also thought about another way to clear out the copper between
traces that make work better for me than a hobby knife. In mold
making and other forms of metal working, we use riffler files that
are great for small detail work. I know I have some around so I will
give that a try first before the knife.
