Anode and tank wall distances

[boxgods]

I am building my setup to plate parts that are cubes about 2" x 2" x 2" made of copper with 26 inches of total surface area each and as I need to plate about 200 of these a month, I would obviously like to plate more then one at a time.

I read on Caswell's site that your part/s needs to be at least 6 inches from your tank walls. The tanks that come with the kits are about 11" in diameter...so obviously even one tiny part suspended in the center would be closer then 6" from all the tank walls...obviously the parts can't touch the tank sides, but would a more practical 2" from the tank side be OK?

Next, I could not find any information on the distances the anodes need to be from the part. I understand this probably varies from situation to situation of course, but a general "guideline" would be helpful.

I also noticed that in most of the pictures in the manual and in these forums, that the anode/s are placed along one edge of the tank. If you placed the anode/s in the center of the tank with parts on either side, will this work? In other words, does the anodes lines of "throw" extend out from all of it's surfaces? I am pretty sure they would but it doesn't hurt to ask.

I am including a simple illustration of what I was thinking for parts placement in either a round or square bucket tank with a legend of sorts bellow the image.





The heavy black lines indicate the tank walls. The round tank is the standard bucket tank from the kits and is about 11.75" in diameter. The Square tank is the standard square bucket and is about 10" x 10".

The heavy green line denotes the anode and is 8" long in the square tank, and 1.25" on a side in the round tank (would a round shaped anode work better then the hex?)

The parts in both tanks are about 1.5" from the anode and the same from the tank walls.

The orange circles represent the "safe" arc of the parts as they rotate at 3-6 RPM in the tank for the duration of their bath.

The plan is to first nickel plate then follow with copy chrome as the parts are already highly prepped/polished copper.

Thank you in advance for any assistance/information.
