Hi guys as in
Sure you have read in moving from knife making and clearing the workshop .
This is an electrolyte etching machine , using salt water and an electric current to mark tyre metal .
Black wire to the metal and red to the cotton with salt water , when the water hits the metal it begins to eat into it , you can get stencils made or use nail polish on the metal , scratch with a pin you logo and the machine will just remove the exposed metal .
In good working order , £40 delivered .
