So I bought some new (old) toys and they are a bit rusty.
Currently, I have a cap iron and blade hooked up to the -ve side of a battery charger. The anode is an old circular saw blade (homebase special so no carbide in sight). Both are positioned with wood and cable ties in a plastic box with about 7-10 ltrs of water and 5 tablespoons of sodium bicarbonate as electrolyte.
I'm not seeing bubbles and the rust is still there.
I'm all ears as to why! Connections are obviously solid. Current is 6v trickle - the onboard ammeter reads about 1.2.
