The idea of metal plating stuff for HV gear has come up a lot over the
years.. inner tubes, beachballs, expanded polystyrene foam, papier mache
have all been mentioned and are probably findable in the archives. Another
issue... you're going to need a BIG tank of copper sulfate solution, and
while CuSO4 is cheap, a 4x4x3 foot tankful is going to be quite a pain to
have around.  I seem to recall a discussion of a small trough with a toroid
slowly rotated through it to gradually plate...
Even at hundreds of dollars, aluminum shapes produced metal spinning start
to look pretty attractive (unless you happen to own a plating company)
