well, I have been reading up on anodizing for 3 months now. Have gotten info from USpecialty corp, Ron Newman, other published books, and from Caswell. The lead content of the cathodes where bothering me some due to higher heat the lead based cathodes radiated (USpecialty corp). Ron Newman also suggested 2 alloy types in the 6000 range, I picked one up and tried to use that.
My copper wire is extra long! From university physics, I know the resistance of a wire is negletable in problem solving based questions, but maybe here in this instance it could mean the difference. My rectifier is cradled. I have a wooden box insulated with syrofoam put in a metal casing. Ill admit my wiring was a tad sloppy as per I already took on an anodizing job and wanted to run my test peices and the customers marker though in time. Maybe the wire is touching the metal casing and giving some problems?!?
I am running 4 cathodes, each a Square Foot in size, but only 3/4 is actually in the bath. (so total approx 3 SF total cathode)
ill post some pics:
