I'm looking to do copper electroforming, to a scale of up to 500mm to 750mm surface area. I intend to use copper sulphate and car battery acid. no cyanide based solution..
I am not sure what is an appropriate power source, I do understand that i would require variable voltage, that is 3-5 dc volts, at first, then increased to a max of about 12v, . As copper electroforming is quite simple, i am looking for a cheaper alternative to a rectifier, what altenatives might there be? I am not sure about ampere rating required, i understand this depends on the solutions balance, however i require fine detail. does anyone know of a simple voltmeter ampere meter dc set up applicable to electroforming procedues? |

Try an auto battery charger.. everything you need in one package.. Get one that charges both a 6 and a 12 volt battery. If you purchase a large copper wound reostat and place it in series with the - terminal, and place a voltage meter (a cheap digital one) across the terminals of the tank, you can adjust the voltage drop across the tank terminals to your desired voltages. I've seen the large wattage reostats in surplus stores, you can also order one from one of the major catalog supply houses. It needs to handle around 100 watts or more for long time cycle duty. .... after all, when you charge a lead acid battery, you are actually doing "pretty much" what you want to do. The worst suggestion of your lifetime may be the catalyst to the grandest idea of the century, never let suggestions go unsaid nor fail to listen to them.
