Restoring Old Chisels Using Electrolytic Rust Removal.

I had some old cold chisels inherited from my father gathering rust. Using electrolytic rust removal and a bit of spray paint I will show you how to restore them to their former glory.

Materials you will need:

Rusty tools

Voltage source (battery charger)

Non conductive container

Sacrificial anode

Wire (for wiring tools) cathode

Soda Ash or Bicarbonate of Soda

Fresh Water

Time

Wire the tools and connect to negative of voltage source

Connect positive to the sacrificial anode

Mix the Soda Ash (Bicarbonate/ washing soda) in fresh water

Cover tools in non conductive container with water solution

Turn on voltage source

Wait

WARNING: DO NOT PUT YOUR HANDS IN THE WATER WHILST CHARGER IS ON AND/OR CONNECTED!!

SWITCH OFF POWER SOURCE!!

Remove tools from solution

Remove wire

Rinse in freshwater using scrubbing brush for a few minutes

Clean up metal burrs on bench grinder

Finish in the colour of your choice
