Stephen,

I don't recall where it is written that tire tubes _must_  be filled 
with air.  It might make it much more difficult for the part about 
applying the graphite, but have you considered filling the tube with 
plain old water, or better yet, salt water?  Once in the copper plating sulution
you would have much closer to neutral buoyancy.  Maybe you could place the
tube in the empty plating tank, fill the tube with water, rub graphite on the 
top half of the tube, fill the tank with plating solution and plate 
to desired thickness, then drain the tank and tube, flip over, refill 
the tube, graphite rubdown, refill plating tank just to the parting 
line and go again?  Interesting /problem project!
