I too have used this method regularly first on tractor parts then tools and a couple of motorcycles and lately some old lathe bits.Great method of paint and rust removal on ferrous items as long as u are wary of hydrogen embrittlement common with all electrolytic processes in hardened and high tensile steels. only 3 volts is required but higher voltage helps combat resistance which steadily grows necessitating cleaning of electrodes
A light bulb and ammeter in the circuit to show current flow and bulb acts as a current limiter in the case of a short circuit,and after washing an etch coat of phophoric acid will eat of the black coating of magnitite leaving a passivated phosphate coating resisting rust if kept dry and is a great primer too
