Homebrew PCBs

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


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

I had on hand a small roll of "lead free" solder and gave it a 
try.  The first test is very positive, but I had to increase the 
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 he 
suggested 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 
they recommend 15.5 A/M2.

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