Stormin 4,458 #1 Posted May 25, 2016 I know this subject is posted elsewhere, but as I decided to make a bigger one, I thought I'd do an update. Actually, certain persons told me too. So first a plastic drum was procured from up at a mates farm. Next, the top was cut off. I had these hooks that are for hanging florescent lights from. After cleaning the paint off the hook and the back, they were fitted to the drum. Two eye bolts were also fitted opposite to each other. These for wire or some sort of support to hang the work piece from. Copper wire was secured behind the hooks and out through a hole drilled in the side. Also a wire and crocodile clip secured to one of the eye bolts. The later will attach to the work piece. Sacrificial anodes were made using some box section with copper wire attached, so they could be hung from the hooks. I had an 18v battery charger for a cordless drill lying about, so this has been modified to provide the electric current. The blue wire, negative, is attached to the copper wire running round the inside of the tank. The brown wire, positive, is attached to the eye bolt with the wire and clip on. All that's left now is to fill it with water and add washing soda and it should work. The top will be fitted upside down to act as a cover. Why upside down? The barrel after being cut and having bits bolted to the sides, is distorted. Upside down it fits grand as owt. 2 Westie1 and sten reacted to this Share this post Link to post Share on other sites
Rocboni 257 #2 Posted May 25, 2016 Can the charger provide enough current ? Share this post Link to post Share on other sites
Stormin 4,458 #3 Posted May 25, 2016 Yes! Any charger will do. I've been using a car battery charger. 24 volts would be even better. It's not a fast process, but does allow you to do other things. And being an electrician, I'm sure you can come up with something maybe more suitable. Share this post Link to post Share on other sites
Rocboni 257 #4 Posted May 25, 2016 A car battery charger will be able to supply a lot more current than a charger for a cordless. As far as I understand the more surface area the more current required? 24v at 10amps would be ideal for a tank that size. I would probably go far a mains variac and a rectifier but not cheap. 1 Stormin reacted to this Share this post Link to post Share on other sites

Stormin 4,458 #7 Posted May 25, 2016 Gets rust and muck off. Not a quick process. But allows you to go off and do other things. Share this post Link to post Share on other sites

Stormin 4,458 #9 Posted May 25, 2016 Time depends on how bad things are. Definitely days. Sorry I have no photo's. Got a chassis half submerged in my smaller one. Been in two days. May have a look in another couple of days. Share this post Link to post Share on other sites

Cub Cadet 613 #16 Posted May 25, 2016 I love my e-tank, after 12 hours the paint just falls off. Share this post Link to post Share on other sites
expeatfarmer 591 #17 Posted May 26, 2016 I have an old stick welder connected to mine after a few hours the electrolyte gets hot which makes it all work faster great for stripping off ancient paint as well as rust but eats the sacrificial anodes. 1 ranger reacted to this Share this post Link to post Share on other sites
