I wouldn't worry toooo much about the hydrogen as it's given off in fairly small amounts unless you are using 10's of Amps, and will disipate vertically very very quickly. The main precaution is to switch off the power before disconnecting the leads to the anode or cathode to avoid sparks igniting any gas before it has a chance to escape.

Cheers,
Craig.

Here's a picture of my set-up. A bit of a lash-up, I've been meaning to make some better wires but it's always in use! Rescued attachment Rough rig up.jpg

Craig, Fair point on the hydrogen I wont worry too much about theat then, just sensible caution.

Graham, That setup is very much how I was planning on doing it which is nice to know. But in your picture of the primed de-rusted bits I see you still have half of you bag of soda crystals left, I was going to whack the whole bag in

Graham,

Can't believe I'm going to say this BUT lift the tank up or drop the PSU in level.

Reason, ask which wally turned and knocked over his battery charger from a stool into a drain tray full of oil, whilst switched on ?

One wrecked battery charger, oil everywhere (ba***d stuff) and ripped leads from battery.

Thankfully before I ever attempted electrolysis.

Right I've got it set up and it seems to be doing a good job.

Here's my setup: Rescued attachment PICT1974.jpg

I used some ribbed cast iron plate as the electrode, it gives good surface area and is working well.

I just hung the items up with wire, this didnt connect to one suficently so only one caliper was de-rusted, adding an extra conductive lead solved this. Rescued attachment PICT1982.jpg

Rob,
Good point, I hadn't noticed the precarious PSU ...
Graham, I hope you're still alive and are not too proud to accept a bit of sound advice...

To get you in the spirit, today at work, as part of an I.T. project to build some ticket machines I was asked how many tickets were on a roll of tickets. I started talking in terms of 2 x PI x Radius of ticket roll taking account of ticket thickness and length etc etc until one of my colleagues pointed out that inside the roll of tickets it said "1200 Tickets"... I have no pi$$ left as it was all taken out of me earlier today...

Stay safe,
Craig.

I also had trouble with some computer PSU's.

1) Old AT 200W PSU, only worked on 5V, 12V cut it out.

2) Old AT 200W PSU, worked fine giving about 2-3A

2) ATX 300W PSU, again worked on 5V but cut out on 12V

4) ATX 300W PSU, working well giving 5-6A

so it lookes like some PSU's have trips in them!

Just a note to say thanks works a treat only down side is that im almost finished my kit so would have been handy at the start.

WHAWWL brilliant Top tip

Hardly fixed a car today at work to busy creating bubbles.

Tried a bit of 25mm tube at first and it worked slowly so i made a half circle out of sheet steel that i use on mot repairs and it works great.
There is some rust proofing on the steel that is leaving a green residue all over the plate is this normal or some other more devious chemical reaction.

Can we use a fully charged car battery?

I Think it may cause problems with any inadvertent short circuit as a battery isnt current limited where'ase a charger will current limit or trip a fuse.

cheers

Cleaning drive shafts....

Anyone used this process to clean the drive shafts from a 4*4 LSD. I am concerened about the grease in the joints either end. Is is possible to push the bearings out then clean them. I have removed the circlips and have each drive shaft in three bits with the boots removed.

ta!

Just spent two hours watching my hubs bubble away and WOW this really does work. This is going to save so much time and mess now all i need is a bigger plate and tank.

Now i've got it going can you answer a few questions lads.
At the moment it only draws 1 amp from the charger. It's a 12volt jobie and i'm wondering if the process would speed up if i changed to 24v instead.
Is it possible to up the current by altering the solution at all.
Or am i just being impatient and inquisitive for more information.

Add more soda crystals, that'll speed it up. And move the metal plate closer to the thing your cleaning.

Sorry to dig this old thread back up....

I've been doing some electrolysis of my own over the past few days as part of refurbishing my old sierra front hubs.

Im now at the stage where all the rust has gone and I am left with a black surface. I had a brief scrub with a wire brush to remove the last bits of 'flaky rust' and found that this black surface brushes off to leave a more silvery surface underneath.

Are people painting onto the black surface, or blasting that off somehow and then painting onto the silvery surface underneath?

Thanks

Hi,
As said above, scrub the black stuff off and paint immediately. Don't leave it lying around as it will rust again very quickly. Use an etching primer if you can or a zinc based primer to get a good grip on the bare metal.

Cheers,
Craig.

Just a note on the anode material used in the solution for this process. Using nickel rich material like stainless steel will create a solution that contains nickel. Nickel solutions have been linked to cancer. Stick with the iron/steel as an anode.

I think this has been asked before but after scanning through I haven't found a definate answer,

Can Alloy parts be used in the same process, like alternator casings etc? or does it only work on cast and steel pieces.

Ally doesn't rust in the first place so there isn't any to remove. Something might happen to ally in the tank but I dont know what. Why not find out on something disposable?
