I set one up using zinc flashing from Amazon, a DC power supply I had (D cell batteries work too if the parts are not too big), vinegar, Epsom salt and some copper wire, I also bought some zinc chromate from Caswell Plating. I plated the rear brake arm and rod which meant I needed a long bath. The large plastic tray I used needed a lot of fluid. This turned out to need quite a bit of current but it worked, I will be doing other parts of my K3 as I take it apart. The zinc chromate step was a learning curve. If the part is not absolutely clean after buffing the chromate does not work. A good place to start is Arnold's Design on Youtube. He has a great tutorial and it's pretty cheap. The smaller the vessel you plate in the easier it is, I needed a larger one due to the length of the brake parts. As I move forward, I will set up a small vessel for small parts.
Note: muriatic acid (pool acid) removes old plating. Old rust can be removed with vinegar or electrolysis. I have been using vinegar, it's pretty easy and nontoxic.
