Paint/rust

[rustywrench]

With regards to this battery charger rust removal. I tried this one myself but to my dismay the charger quit working after a few minutes so I resorted to evapo-rust from Harbor Freight with good results.
My question: I used DD's recipe so is this process hard on chargers or perhaps it was just my chargers time to die?
I would really like to use this one again (cost effective) but not if it is hard on chargers. Any feedback would be greatly appreciated.

I had much success w/ DD PH method. I used a good car battery and just used the charger to keep the batttery maintained. I think if the bolt were shorting out on the inside of the tank it might cause troubles. I used solid copper home wiring , so that I could bent it to keep shape and position the bolt where I needed it inside the tank. This process seemed to take a long time. Cleaning the bolt off repeatedly. The worse the tank the longer the process. I must say though the finished product looks superb.

Thank you Goody for nudging me in the right direction. A good friend recently suggested a sealed beam light to act as a resister, however the battery between tank and charger would certainly do the trick. Hadn't even thought of it but I sure will try it soon as I get my tank back from a friend to remove some dents. One step at a time as they say, Thanks again, RW

Your welcome . I even had good results w/ just the charged battery alone. Only hooking up the charger when I was around to keep an eye on it.

I also use the charger method. I found an old 10 amp charger at a garage sale for $2. All of my newer ones won't produce a current unless hooked to a good battery. I also use solid copper wire from romex, and change the bolt, or scrap metal every few hours, and top the tank off as well. It's really important not to let the metal touch the tank. That may be what killed your charger.

I tried the battery charger method earlier this year on my CL77 tank. Absolutely brilliant. I wish I'd trued it years ago. No nasty chemicals just washing soda and electricity. I've de-rusted all sorts of stuff with it. I've even seen a setup using a large pool (straw bales covered in polythene sheet) which someone used to derust a truck chassis. The juice in that case was a welding transformer!

I don't like the sealer gunge inside my tanks - I've spent too many hours cleaning flaking crap out of carbs. Just get rid of the rust and if there are any holes - weld them up.

"No nasty chemicals just washing soda and electricity." Hey G-man, "washing soda" in Americun english=what?

I think I've got the basic idea, but anybody got a link with good instructions for how to do this, just to be sure?

Thanks, Lee
