I used (2) one-half inch by 10 inch
bolts. I dunno if they'll last as long as stainless, but
they're cheap and easy to get. I just ran the thick copper wire
right down to the bolts and wrapped it around em a few times,
then wrapped it with electrical tape. Very low-tech but it
seems to work great on the 2 amp setting of my car battery
charger. Alligator clips with wires already on them can be
bought in the automotive-electrical section of fred meyers.
They are called "jumper wires" and cost 1.50 for four. Not bad.
PS: the rod on top (in the pix)
which they are hanging from was originally a screen door spring,
but that heated up too much from some resistance, so instead I
found a steel rod in my basement that just so happened to be the
perfect length and size. (ok, i borrowed it from a rock grinder
hand-rest that I have).
I shock six coins at once, for about
15 mins... and it works. I probably have enough room to add two
more coins for eight or so at a time.
Thanks to Tom for the great idea!
Much simpler and more productive than my four seperate tubs
idea.
