Thanks for the help. Acutally, I am using a potentiometer (not a rectifier)to control the current and my battery pack is made up of 10 AA nicads that have plenty of power. I also tried another set of nicads that had 3.7 volts but even that is too little according to your setup. The bottom of my anodes are getting dark and burnt looking so I thought this was an indication of too much power. I have been heating the solution to the recommended 110 degrees but your setup was at 65 degrees.
I have a glass bead blaster which I have been using but I haven't been using an acid pickle because I didn't think I needed to.
I'll give your method a try. Thanks again.
