    Electro-etching Metal Using a Stick On Label

    This video shows how I use salt water, a power supply, and a stick on label to mark aluminum and steel. This procedure should be done in a well-ventilated room or outside.

    Hey Rick, Iíve tried doing this but I had my electrodes backwards. Would you say that that would make a difference or do you need to do it with them the way you did it. Also if you used a material specific electrolytes as your medium, do you think the results may be deeper or not?

    Thanks,
    Mike S.

    Mike,

    The polarity is critical. The target metal must be positive relative to the salt water soaked Q-tip.

    I have not tried different electrolytes but would very interested to know of liquids that would cut deeper into aluminum and also steel.

    I do understand that in the commercial electric etching provides electrolytes for the base metal you are etching. Iíll get some and try it. It has to work better or why would they include them in the kits?? Thanks for the reply. Iíll switch my electrodes and see if that makes a difference for me. What voltage are you using and are you using a power supply or batteries?

    Thanks,
    Michael

    Michael,

    I'm using a 20V at up to 2 amps power supply. Be very careful using batteries that can put out more than that. For example, do not use a car battery.

    I'm going to try this! I have a vinyl cutter so making templates is a breeze!

    Thanks for sharing!
