Thanks M_D.
I noticed a piece that I anodized was swinging wildly in the tank, the agitation was so vigorous that the part hydro-planed. My agitation system cycles all of the electrolyte in 43 sec (the proverbial "tempest in a teapot"). This is actually more agitation than anyone would need short of Type III (hardcoat). Nothing broke, and it was very small wire (22 AWG). More careful wire placement would have elliminated the hydroplane effect.
Another idea for multiple large-ish pieces is to weld the wire to the work and to an aluminum bar which suspends them and controls the part spacing, don't make the wires any longer than necessary. The bar becomes the common connection point. If the job will tolerate this, use a second wire for stability and/or larger wire. The bar stays out of the electrolyte, this removes nearly all parasitic resistance (no rack) which will improve accuracy, reduce the required current, and lower the power dissipation.
I now have over $ 9K of my own money invested in the CDW, and 8 months of work, I'm not about to post the schematics and just give it away. I know I promised more information in July; sorry guys, I need a little more time. When you know why; you will understand, and you will be pleased that I went the extra distance.
