I plan on nickel electroplating several Lionel prewar parts. The last several days, Ive been working on making a batch of nickel plating solution (please see picture).
Reading online, they say to calculate the surface area of the part that you want to plate, which will help determine the voltage. Because of the odd shape of these latch couplers, I'm not even going to try and attempt to figure out what the surface area is, lol. My question to the group, for small parts such as these, what approx. DC voltage should I use?
