Re: Silly Q on home made chiller, improving cameraman's design
I beg to differ! I have been using pieces of 6061 aluminum as my cathodes for a couple of years now. They are thin, maybe 1/16" plates. When I first started using them I would take them out after each days run to clean them off etc. I haven't taken them out of my acid in over a year I think and they are more than fine still! I do wonder alittle about the disolved aluminum in my acid mix but so far no problem. Also lead is a very "dirty" material and you have to worry about impurities in it getting into your mix. Again aluminum is heads and tails better to use than lead. As for the pump. I don't know what model pump he is using but there are many pumps of this type that area mag drive pumps, they have no steel shaft turning the rotor itself. Making them acid safe. Pumps that are acid safe use a ceramic shaft that is acid safe. They cost alittle more but it's all what you want out of what you spend.
