Electrolytic small parts cleaner
#17
Two problems with alloys. One is that copper and chrome can go into solution and plate on the part. I can't see this as a problem with stainless, but a good reason not to use any ol' piece of metal you have handy. There is a bunch of stuff out there on the net with the chemistry wrong. I can vouch for this site http://www.holzwerken.de/museum/links/electrolysis_explanation.phtml which includes a few balanced redox equations and references to x-ray diffraction for the truly sick. Not only is it well written, but it gets the chemistry right.
Two reason to use steel bolts for the anode rather than stainless. First is that everyone who reads this has a good supply of just functional 5/16 nuts and bolts that they wouldn't mind making a bit more rusty and then tossing. Second is that it provides a low budget ammeter; if the anode rusts, you have it set up right. Stainless is safe, and if you are building a thing of beauty like eman's you should certainly use stainless so it stays nice.
I think the best way to screw up safety wise would be to use a strong base like lye, or to put the lid on the kitty litter container or 5 gal pail. (Search you tube for Hindenburg videos before doing that.) I work outside so ventilation is never a problem. (This weekend I was ventilated with gusts to 20mph.) Shorting the part or basket to the anode would also be bad. And high amp arc welders as a power supply would be a little Tim the Tool Man. The prop shaft of the USS Monitor sits in a vat of electrolyte at the Maritime museum in Newport News. The little tiny wire attached to it is certianly not carrying that kind of current. And I think that (other than my wheel cylinders) that is the rustiest part I've ever seen. I'd sure like to know if anybody has found any other ways to screw this up

Found the site where they did a trailer frame(I said truck frame earlier).
