Introduction: 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.
Step 1: Watch the Video
Step 2: Materials
Materials you will need:
Voltage source (battery charger)
Non conductive container
Wire (for wiring tools) cathode
Soda Ash or Bicarbonate of Soda
Step 3: Electrolytic Rust Removal
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
WARNING: DO NOT PUT YOUR HANDS IN THE WATER WHILST CHARGER IS ON AND/OR CONNECTED!!
Step 4: Removing and Cleaning Tools
