I agree, he has put quite some effort into the apparatus.
However I really think he shouldn't of tried building the
entire thing in one step, unless he had lots of experienced
with the process and is familiar with copper plating tank
design. For example it looks like he plans not to fully
suberge the copper anodes and will inevidably get large
amounts of oxidation at the air liquid interface. He also
has some mild steel and brass around that area. Unless he
will NEVER spill a drop of solution, this will corrode and
ultimatly contaminate his bath will iron(II). As for the
other tanks which I assume are for the electroless copper
stages, I don't have any experience with so thats a whole
different set of challenges he must deal with.

Imagine conductive salt soluions (especially the sulfuric
acid copper plating at 4.8 ohm-cm at 20°C) shorting the
transformer and blowing the fuse, which I sure hope he has
installed one.
