How Many tanks ?

[micronind]

I have a somewhat simple question, I'm reconditioning some machine shop equipment and want to setup some plating and anodizing lines, can someone tell me how many stations / Tanks are needed to setup a proper complete line for Hardchrome for anodizing for yellow chromate and for Black Oxide 4 lines total. I just called to order chemicals and the manual from Caswell but would like to Order the tanks and start to build frames this coming week . One last question is should there be any set distance between the various tanks if done properly, Thanks in advance RD
