For rust removal or for plating?
I've done both...
Rust:
IN A WELL VENTILATED AREA, OUTSIDE FOR PREFERENCE!!!
Big plastic tub.
Fill with water
Add soda crystals (about 200g for 20 litres)
Mix well
Clean rust free sheets of steel or rods (NOT STAINLESS OR PLATED, JUST RAW MILD STEEL)
Line the tub with the steel, make sure its all touching or wired together, and clean Steel is poking out the water by a few inches. Use clamps.
Connect that to the POSITIVE side of a variable current 12v supply where it pokes out of the water (you can use a battery charger but its not ideal cos you need to be able to control the current, if using a battery charger then put a built in series on the positive side when you connect it up)
Hang the piece you are de-rusting in the water so that it does not touch anything, not the bottom, sides, and make sure what you hang it with doesn't touch anything attached to the steel you lined it with either.
Attach your piece to the negative side
Switch on.
Lower current = slower, more gentle rust removal. Higher current will blast rust off but is more brutal. Use low current (couple of amps) for intricate items with details that need to be retained. Use high current (10+ amps) for lumps of pig iron.
It takes days. Clean your steel now and then, it will need it.
Plating... What are you plating?

Cheers guys, it is just for rust removal for now, replacing a load of rear suspension components on the daily and and wanted to clean up the bits I'm keeping, once I get the hang of it I will move on to more important stuff.

Get some rubber washers from the plumbers or B&Q for the bolts one each on the inside should do it or use PTFE tape

Meaning to do that for ages, I bought the washers two or three years ago... Would be nice to be able to get the water level just a bit higher.
My idea was that constructing it this way it would be easy to replace the anodes (12mm rebar left-overs with threaded rod cut-offs welded on) or the tub, which is a standard size you can get at any builders merchants (in the Netherlands). This was my "prototype", I planned to make one with a new tub at some point, but this one has actually been working fine for about five years.

You might also want to try citric acid (or a commercial product like Deox). Have a look at my build thread, towards the end, I've tried electrolysis (not as advanced a set up as above) and citric acid. I prefer using citric acid. There's also an article in issue 2 of Street Machine about electrolysis and loads of info on YouTube and/or instructables |

I use electrolysis in my workshop in NL; at home in UK and IRL and for quick and small jobs I use Bilt Hamber Deox-C, which I can highly recommend. I've also tried Evapo-Rust, which works much like Deox-C but costs a lot more.
