Plating worn trumpet valves
I need to build up the diameter of a set of worn trumpet valves (approx 2-3 thousandths of an inch. The valves appear to be nickle plated. Should I strip the existing plating with nitric acid, build up with copper plating, and finish with nickle, or can I just over-plate with nickle?
Also recommendations on temp/voltage and amperage. I would plate in a 1000ml beaker with titanium anode.
