Thanks Seanc, you are the man ! I am starting to get my head around the circuitry now !
I am having better results now I am ignoring the volts, and my surface area calculations were also wrong. My plating is still comming out really dark though, but shines up really well with a wire brush. As you say the amps per square inch that Caswell recommends seem too low, what is the difference between the old kit and new kit ? mine was bought in England about a year ago and the electrolyte came in concentrated form ( no dry Pack of Cyrstals ) which kit have I got, and how many amps per square inch and temperature do you recommend for me ?
In My plating manual there are two pages with the instructions for copy cad / zinc kits, and they both have conflicting instructions for current !
Caswell seems to recommend 1A x 40 square inches which is 0.025A per square inch ? that seems very low to me, I think I read on your page that 0.05A per square inch gave the best results, but others on the forum have talked of using 0.1A per square inch.
For some reason I Never get any bubbles or fiz comming from the part, I have watched the video on your site, I even tried cranking the Amps way up on a test piece and still no fiz - What gives ? could this be related to my dark plate problem ?
