Copper plating

We've got some banjo tuning machines that are chrome plated, and (for esthetic reasons) a customer wants them plated with copper.

Other problems that I'm not anticipating? Thanks, Alden -- Alden F.M.

Absolutely sure - he wants copper. It's kind of a long story... but he made a bunch of the trim pieces out of copper, and he wants the tuning machines to match (fair enough). I'm hoping that we can buff the machines and lacquer coat them so they stay looking polished. If not, so it goes. Alden -- Alden F.M.

Copper plating
copper will react to hand oils while the chrome for the most part will not.

Other problems that I'm not anticipating? I think chrome must be stripped before copper or nickel can be plated, but the place that would do the copper plating can easily do that. If they also do chrome then they strip old chrome routinely. Since your customer is making other parts of copper, you might use whatever protective coating he uses (if any) so everything tarnishes at the same rate. |
