I picked up supplies monday after work for a quickie start at this first attempt. Home Depot has 12” and 24” 3/8 rebar at affordable price tags, bout some 12 gauge wire, a tub. I was unsure about laying this rusted Jet handle rod right on the bottom of the tub so used some scrap plywood to raise it up. Connected my negative battery charger lead right to the rod under the water and positive to the copper ring attached to the rods. Fully expecting a nuclear explosion in my garage, I plugged in my battery charger and turned it on to the 10 amp selection. Bubbles immediately started to arise from all 4 rebar rods and from the Jet handle rod. The battery charger looked to be hovering around 1 or 2 amps (can’t exactly tell due to the dial not being specific under 10 amps). Let cook for 12 hours. Not too shabby of the end result, but I know can be done better. I forgot one thing: the battery terminal alligator clips are made out of copper. Oooops.
Tonights attempt I used steel cable from exercise gym I have laying around to hold the 2nd rusted Jet handle rod up off the bottom of the tub. 3 gallons of water + 3 tablespoons of washing soda. This time, the battery charger is upto 5 or 6 amps. Will see what happens come morning.
