After several false starts I got a board ready to etch. I went to Radio
Shack and bought a bottle of etchant. It was a chilly(68 F), rainy day
so I put enough etchant in a plastic dish to cover the board a quarter
of an inch. I stirred it cautiously and it had barely started to etch in
15 minutes. I warmed it gently with a small heat gun up to a little over
100 F occaisionally. It took an hour and a half to etch. I may not have
shook it up enough so my next attempt will be with the rest of the
bottle in a bigger dish.

For the moment, picking a broken drill bit out of one of the holes is
the next challenge! We don't all have success the first time around.

BTW, am I the only one to ever get the printer output to the wrong scale
and not discover it until I drilled the board?

I am getting closer!
