Thanks Herb!

The brass was the .005 inch thick sheet that came with the etching system. It took about seven minutes to etch completely through one side, and I just dangled the unfinished side in with the pair of plastic tweezers for about two more minutes to complete it. Believe it or not, folding the dang AC unit without deforming it was the hardest part of the etching.  All the soldering except for brass to brass was done with cerrosafe. I made thin soldering "sticks" by ladling a thin line of it out on a sheet of glass.
