DIY electrolytic metal etching with 9V batteries

First of all I placed the vinyl stencil in the position I wanted.

Then I connected the batteries in series, using alligator clips. I connect the positive pole of the first battery with the negative one of the other.

Now I had two poles empty. The positive one went to the metal of my tool. On the negative I added an ear scoop.

In a small container I added vinegar and salt and I mixed them together.

Then I dipped the crocodile clip in the vinegar and salt mixture and touched it on the metal parts I wanted to be etched.

I repeated the last step several times for about 10 minutes.

And that's it!



Many thanks to Opus Decor for producing the vinyl stencil.
