Thanks for the additional info, Jim. It's mainly a curiousity to me at
present, but plating small parts with nickel to inhibit corrosion and/or
improve conductivity could be a very useful procedure if it's not too
complicated.

I'll be having a closer look at Caswell's products and kits.

I'm wondering what plating materials can be applied to polished cast

I sent machined aluminum microwave radio enclosures out for nickel
plating because it was cheap and maintained conductivity between the
cover and chassis better than the bare metal over time. These were
prototype aircraft radios that may see condensation when descending
into humid air. IIRC the lot charge was about $80 fifteen years ago.

I think nickel and copper plate well without cyanide, copper from the
sulphate and nickel from the acetate, but I haven't tried it.
