Caswell home plating supplies has a kit [1-1/2 or 2 gallon] for "Copy-Cad'. It looks like cadmium or zink plate but is not toxic to mess with like cadmium. The pic shows my copy-cad tank; the anodes are sitting on top. The savings are great because you don't have to drive somewhere to have it done [for me that's 100 miles each trip]. Even better...you get it done that day! Even better than that there is no chance of valuable parts being lost...that has happened to me. Simple to do...plates and solution last for many years, easy to store and set-up again. Although mine is left set-up and ready. It and the nickel tank are used often.
