The above soloution is fine IF you are going to submerge the object to be
plated in the plating soloution (I'd love to see you try plating a 6 foot
sphere that way) If you look at my origional post I overcame the size
limitations imposed by immersing the sphere or toroid in the soloution by
instead saturating the soloution onto a foam brush connected to the
positive side of the power supply and using a painting action to plate the
surface which is connected to the negative side of the power supply.

NOT SO! You forget there are two forms of copper chloride;
1. copper chloride (ous) CuCl or Cu2Cl2 mole weight = 99.03 solubility
per 100 ml. in cold water = 0.0062 gm.
2. copper chloride (ic) CuCl2 mole weight = 134.48 soloubility per
100 ml. in cold water = 70.6 gm.
I was speaking of #2 and I think you are speaking of #1
