Reading Think and Tinker's gives one the notion they can do this (almost)
easily at home. Plating is deposited by electroplating at about 20A/sq.ft.
Copper, bright tin, and solder are the typical platings, and differ only in
the anode bars and electrolyte. For the small boards that I do, I think I
can easily manage a DC supply to source 5A into the 20'ish milliohms in the
bath.

Some evening this week, I think I'll have a walkabout through WalMart and
see what tubs are easily available for making into plating baths. I think a
wallpaper wetting trough might be too long, but perhaps there'll be
something the right size in the garden center. Actually, a rectangular
tupperware thing with a tight fitting lid will be ideal, I think.
