So far, so good.
This is an old pulley block I bought the other day (w/ sheave) and I am removing the rust from it via electrolysis. I've already sanded and oiled the sheave. It's waiting on the bench now.
I have a 5 gallon bucket full with water and 5 tablespoons of Arm & Hammer Washing Soda, and have a piece of sheet metal bolted to one side. The pulley is hanging from some annealed wire from a stick.
Negative to the pulley (cathode), positive to the sheet metal (anode). I'm using my 12 volt battery charger/car starter for power. When this picture was taken, it had been about 2 hours in the cooker.
Now, after 4 hours, the water/sodium carbonate is REALLY murky. Should have a nice bare metal pulley block sometime later today. This is EASY!!! Can't wait to do more.
