Well, if I'm in a hurry I can hand etch with hot FeCl and a sponge in
under a minute.  For now, with the CuCl, I just put it in and go do
something else.  Usually work ;-)

Once the CuCl bath is fully built, it should etch in a few minutes.

The tank has an air bubbler in it to keep things moving around.  I
might build a new bubbler rig to get more even air bubbles, and on
both sides of the board.

Meanwhile I move the board around every 10 minutes or so.
