LanceVance Posted December 16, 2011 Share Posted December 16, 2011 (edited) Haven't seen many posts regarding electrolytic rust removal. Considering rust is something that all of us (at least most of us) have to deal with, I figured I would post up my results! I recently purchased this turbo manifold from a member on here, and it had the typical amount of rust. It will eventually get ceramic coated when I have a turbo to coat as well, but untill then I figured I would try this out. I followed the instructions found HERE. Manifold as it arrived... Worst area of rust... The bucket and anode... After sitting for two days, this is the anode, complete with holes... Anode and Cathode (the manifold) together... The manifold after about 1 hour of brushing by hand... The turbo gasket surface. Can still see the line of the old gasket (Might end up doing some porting!)... All in all, it came out much better than I expected! There is still a bit of rust around the ends of the runners, which was farthest away from the anode. I might just throw it back in for another day with the runners facing the anode this time. Turning the manifold would have given more even results (next time ).

kiwi303 Posted December 16, 2011 Share Posted December 16, 2011 I've done pretty much the same on an old (1940) SMLE barrel... came out shiny! Quote Link to comment Share on other sites More sharing options...
Lazeum Posted December 17, 2011 Share Posted December 17, 2011 Good job, it looks good! I believe everybody working on old car should know this technique. It's my dad's blacksmith who's also restoring old guns who showed me how to proceed. Beware that this technique however would create some hydrogen molecules that makes flexible parts somehow brittle; something to think about if you try to remove rust from stab bar or springs.

Tony D Posted December 17, 2011 Share Posted December 17, 2011 Yep, it ain't rocket science. Actually, if you have one of the Caswell home plating kits, you got most of what you need. I was taking manifolds (headers for example) de rusting them via this method, and then directly plating them for storage. Quote Link to comment Share on other sites More sharing options...
surpip Posted January 10, 2012 Share Posted January 10, 2012 Nice all have to try that one of these days Quote Link to comment Share on other sites More sharing options...
Lazeum Posted January 10, 2012 Share Posted January 10, 2012 To give you some more motivation, here's the result of last weekend: front bumper brackets after 5h sitting in electrolytic bath and 20s literally with wire wheel (not the small one on the picture) to clean up the residues, paint included.

Moltar Posted January 12, 2012 Share Posted January 12, 2012 What did you use as your power source? Two days seems a bit long. I've done similar work with a car battery charger wand was done after 4-6 hours. Quote Link to comment Share on other sites More sharing options...
LanceVance Posted January 12, 2012 Author Share Posted January 12, 2012 I used this battery charger. Two days may have been more than necessary, but like I said there was still a small amount of rust on the runners. Turning the manifold every few hours may have cleaned it up completely in less time, but I wasn't in a hurry either way. Quote Link to comment Share on other sites More sharing options...
Lazeum Posted January 12, 2012 Share Posted January 12, 2012 A friend of mine tried with an arc welder. In 20 minutes, you might be ok but I'm not responsible for any conequences that may occured Quote Link to comment Share on other sites More sharing options...

kiwi303 Posted January 14, 2012 Share Posted January 14, 2012 Hopefully one with a DC output setting. and a non-smoker around that H2 output! Those electrolytic baths are low voltage H2O to 2(H2)+O2 hydrogen generators... Quote Link to comment Share on other sites More sharing options...
SoC MATADOR Posted January 18, 2012 Share Posted January 18, 2012 Sticky for sure! Quote Link to comment Share on other sites More sharing options...
