0corradini 11 years ago Well, first of all, there's a VERY easy, fast way to at least COPPER plate it -- a copper sulfate solution. Which, btw, is pretty magical. You just dip an (cleaned) iron or steel item in it, or even brush it on -- and whammo - you've got a copper coating. Here in the US, they sell copper sulfate at hardware/home & garden stores everywhere (EXCEPT the San Francisco Bay Area, where I live) - I'd imagine it's easy to find in SA. (If not, it's easy to make: search for "NurdRage" and "Copper Sulfate" on YouTube. I have a batch right now - made with a copper pot scrubber, some hydrogen peroxide, and some drain cleaner.) Safety warnings: it'll eat little (or big) holes in your clothes, which you may not notice until long afterwards. (Don't ask me how I know this.) It's not super-corrosive to flesh, but you do NOT want to get it anywhere near a steel sink, or anything else you don't want to be copper, instantly. You could just copper-plate the wheel, then put a serious coating of protective clear polyurethane spray on it to keep it from going blue-patina. The copper (or even brass) is not going to stay on the wear surfaces no matter what you do. Previous authors are right - it's often best to strike a copper base plating first, then plate onto the copper (nickel - which wears much better! - or brass, etc.) Check out caswellplating.com for more info.
