Rhodium baths for larger articles

Hoping someone can give me a nudge in the right direction…

My rhodium bath at work is great for smaller items, but I’m now
having a need to be able to do larger ones such as bracelets and
necklaces. Can anyone recommend a reference that has useful info for
setting up a larger bath? IE: anode sizes, bath shape, how much
solution, does voltage need to change? The last thing I want is to
waste time w/ ghosted nasty large pieces that I’ll just have to
fruitlessly compound down to the gold again.

thanks in advance,
