Stitch Posted November 23, 2017 Share Posted November 23, 2017 I have an old manual charger you can have. I de-rusted a bunch of hit miss engine parts with it. I bought another this summer at the flea market and this one is sitting around doing nothing useful. Just stop in and pick it up! Quote Link to comment Share on other sites More sharing options...

JHCC Posted November 26, 2017 Author Share Posted November 26, 2017 Random thought: I have some pieces of galvanized pipe that need the plating removed before they can be welded. I wonder if using them as sacrificial electrodes will take some or all of the zinc off…. Quote Link to comment Share on other sites More sharing options...
Stitch Posted November 26, 2017 Share Posted November 26, 2017 Hi John, If you have Galvanized or Zinc around... get rid of it!!! Lol! I use muriatic acid to remove plating. It works fast but I believe they have the death penalty in your town if you bring it into the city limits! BTW, I located the charger. My son "Borrowed it for a day" a month ago. Stop in pick it up and hit some steel! Quote Link to comment Share on other sites More sharing options...

Just as soon as I paint the living room........ 2 tone Das, replying on this thread so as not to clutter up the other....... Like was said, just wrap a piece of wire around a clean spot ( I like copper) and hang it. This pic is showing several pieces being cleaned (hanging on the aluminum channel) and several sacrificial electrodes (clamps on the outside edge of the tank). You can add as many parts and electrodes as you want. But will be limited by your chargers output. Just don't let yer wires cross.....

Hans Richter Posted November 27, 2017 Share Posted November 27, 2017 I was curious about the possibilities and the low aggressive method (no solvents, no acids) and tried to build my own de- rusting apparatus. Unfortunately the battery charger (motorcycle) turned out as not powerful enough. Build a cathode cage from rebar and start with a couple recovered raw horse shoes. Looking for a more powerful charger now on second hand sites. Greetings, Hans Quote Link to comment Share on other sites More sharing options...
Daswulf Posted November 27, 2017 Share Posted November 27, 2017 I just realized that I must have had a dyslexic moment last night. Ugh.. I hooked my leads up backwards. I even double checked which way they go before hand but upon looking at different setups online something caught my attention and I double checked the picture I took and it dawned on me. Oh well. I'll reset it up again correctly when I get home from work. Quote Link to comment Share on other sites More sharing options...

Daswulf Posted November 27, 2017 Share Posted November 27, 2017 Can't wait to see how cruddy the piece I wanted cleaned is when I get home. Guess I have bumped my head too many times. Good thing I don't defuse bombs. Quote Link to comment Share on other sites More sharing options...
JHCC Posted November 27, 2017 Author Share Posted November 27, 2017 Seriously, though, does anyone have any thoughts about using electrolysis for removing galvanization from pipe? I've got a lot of different sizes of conduit that I want to cut into 3" lengths and weld together as tool holders, but I'd prefer to avoid acids if possible.

Daswulf Posted November 27, 2017 Share Posted November 27, 2017 Well, electrolysis Was happening. Lol. Got the leads swapped so it will derust the piece I actually wanted de rusted. Think I'll be wearing gloves next time I get something out of the tank as well. Concentrated rust water is pretty nasty. Of course as soon as I picked the wet rusty piece up I got a phone call...

Dave51B Posted November 28, 2017 Share Posted November 28, 2017 I just thought of some more things.....If you put yer hand in the water with the charger on and the pieces still hooked up you can get a FEEL for the process. It's a rather SHOCKING experience. For me, this only happens in the line of site path. It's kind of handy to determine if you process is working, if your charger does not have an amp meter. Also, if you find the need to speed up or slow down the "cookin'",(as I sometimes call the process) the manual settings on your charger....ie: volts and amps will give you some control. On very large parts with clean sacrificial electrodes, the 6volt setting may be used to keep from overloading yer charger. I would not recomend cleaning non ferrous metal. It may not hurt, but I don't push my luck. Hmmm....Now I wunder...Do you think it will remove scale from a forged piece? I see an experiment in the works.... more to follow if ya need it Life is Good Dave Quote Link to comment Share on other sites More sharing options...
Hans Richter Posted November 28, 2017 Share Posted November 28, 2017 Gents, it's finally works -buy a new charger for about 40 bucks (probably from China) but with Amp-meter and selection switch for 5 till 20 Amps and 20 till 80. There is also an external fuse easy to change if overloaded. Very curious wat I will find tomorrow morning. However the rust is floating and the bubbles rise up. Dave keep the life 'sparkling' so there is no need on hair spray or a pacemaker Cheers, Hans Quote Link to comment Share on other sites More sharing options...
Daswulf Posted November 28, 2017 Share Posted November 28, 2017 Success! A little wire brushing to get the black stuff off and it's now down to bare metal. Now to get this all setup and going with multiple pieces. Quote Link to comment Share on other sites More sharing options...
Dave51B Posted November 29, 2017 Share Posted November 29, 2017 yer gonna need a bigger tank....Ha Don't forget to brush off your sacrificials also.....they deteriorate. Enjoy Dave Quote Link to comment Share on other sites More sharing options...
Daswulf Posted November 29, 2017 Share Posted November 29, 2017 Yes I will. I have been since you had mentioned it. I really appreciate the nudge and advice. This is really cool. I have more going now. Before long I'll have a bigger setup. Can't believe I waited so long. Quote Link to comment Share on other sites More sharing options...

In that case here is another tip.....a pressure washer comes in real handy when cleaning parts and electrodes on a bigger setup. After that I'll let you in on a tip of how to keep those parts from re rusting immediately. Life is Good Dave Quote Link to comment Share on other sites More sharing options...
Daswulf Posted November 30, 2017 Share Posted November 30, 2017 I have a good pressure washer. just cant use it during the winter. hit these with wd-40 for the time being. ALWAYS up for tips and pointers. Quote Link to comment Share on other sites More sharing options...
