I am in the process of trying to do it based on this man's work:

http://transistor-man.com/electroplating_busbar.html

I had on hand a small roll of "lead free" solder and gaveit a try.  The first test is very positive, but I had to increasethe current density to 13.5 A/M2 instead of the 10 that he suggested.Also noted the current he used was not based on the 10A/M2 that hesuggested so it looks like it will take a bit of testing to get it right.
I also looked up the recommened current density on Caswells site and theyrecommend 15.5 A/M2.

The power supply I was using was flaky so just got a new one in yesterdayand plan more testing in the next few days.

I have had some success with the tinplating product sold by Rapid Online but it requires the copper surfaceto be extremely clean or results are patchy. Once made up the solutionlast for about six months in a well sealed plastic container(supplied).
