I cleaned and polished an old copper contact bar I had laying around to test if this silver plating set up would even work.
I set up a hinged lid mason jar and put the plating solution in it. I cut the end off an old 3v 200mah charger I had laying around, and soldered gator clips to the ends. Attach the neg side to the copper contact and the pos side to a .999 fine silver strip. Used my soldering 3rd hand tool to hold the copper contact in the solution and bent the end of the silver strip to hang on the side of the jar into the solution. Plugged it in and the submerged part of the silver strip turns a blackish brown, and the copper contact starts to bubble.
It only took a couple of minutes to see results. The contact now had a off-white powdery oxidation to it. I polished that off and under it was silver plated copper. IT WORKED!!!
The plating is a bit thin, but another dip for a while longer will take care of that. Then a proper polish and cleaning to make it look nice and neat. I am going to finish it all up tomorrow. I am really excited about this, I have a few things I want to try to do with this electroplating rig.
