There's plenty of posts and information on electrolysis rust removal, so I'm just going to cover my set up briefly.
After using this for restoring old hand planes, I know that the smaller the bucket, the quicker the results. The electrolyte is washing soda, using about half a cup to around 5 litres.
My positive anode is my old file, works perfectly here as it reaches the full depth of the bucket. For the negative current, I bought single strand electric wire (90c/metre) and stripped the insulation as required.
Finally the power supply. Previously I have used a battery charger, with OK results. I am aiming for 12 volts and 4 amps. I found this transformer for under $30 at Jaycar Electronics. It is 240V AC to 12V DC @ 5 Amps - perfect. It is designed to supply 12V fridges, so should run for a while. I removed the plug end and fitted alligator clips. Now to put it to work.
