This is the second zapper that I made, my first one was just like the small one with the step by step instructions.  With this one I can zap 10
or more coins at one time.

This anode is about 14 inches wide and 7 inches deep.  It is made from 3/8 inch stainless steel pipe nipples.  It is robust and will last for many hours
of zapping.  I designed the anode to be a complete circuit, I felt that if the electrons left the coin in the most direct route possible, a better job might be
accomplished.  This has yet to be proven.


Here is the cathode, it is made from a piece of 1/4 inch stainless tubing.
This is a sample of the clips I use to attach the coins to the cathode.  The copper wire is 14 gauge and was easily shaped with pliers, then soldered to
the clip.
Here it is, setup and ready to go.  Notice how the electrical connections are made.
Once you understand the principle of electrolysis, the imagination is the only limit to the designs that you can come up with.
