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!
