If you build up around the sides with modelling clay so it holds a bath, with the stencil at the bottom, then just leave one electrode submersed in the bath. you get a very even etch because it etches the entire pattern at once, and you can vary the depth by timing it, more time or more current means a faster rate of etching. it also means you can walk away, and not have to sit there moving the cotton swab

I was coming down to write a comment about this but I see it has been done. I assume that the more water you put in the more power but I think that it is more dependent on the surface area that you are trying to engrave. I might try that but if you are planning on engraving more than a square foot I would make sure that you are using at least 4 9volts and make sure the negative is in or close to the average surface area of the area you are trying to engrave so one side is not deeper than the other.

@Drewster 30, size of the bath dosnt really matter, you can just leave it for more time, with the same amount of current. there is a guy on YT called michaelcthulhu and he makes swords, he has an 8 or 9 foot bath that he uses to remove rust, though the same process. sometimes he builds a fire under it to speed it up.

I wonder if it would actually result in an even etch. My (admittedly under-educated in this area) assumption would be that it would etch more quickly if not almost exclusively in the spots that closest resembles the path from the electrode to wherever the clip is placed.

If you have a cutting machine you can get a roll of vinyl to cut out masks. It's the best way to get fine details cut out.

The chemistry behind it: 1. The DC power provides an electric motive force (EMF) that make electrons flow from positive terminal (Iron Plate) to negative terminal (cotton swab). On positive terminal: Fe(on the plate) --> Fe2- (dissolve in solution) + 2e-. On negative terminal: 2Na+(in solution) + 2e- --> 2Na. 2. The newly formed sodium then reacts with water: 2Na + 2H2O --> 2NaOH (dissolve in solution) + H2 (which explains the gas bubble). 3. Finally, NaCl regenerates with the double displacement reaction: FeCl2(aq) + 2NaOH(aq) --> 2NaCl + Fe(OH)2 (which is the dark precipate formed on the cotton swab). The overall reaction: 2Fe ---NaCl, electricity---> Fe(OH)2 (which is essentially the same reaction that makes iron rust, except this reaction occurs in an observable rate given energy input (electricity)

Cool, do you know if this would work on aluminum or other metals and their alloys?

I think using the batteries in parallel might yield better results. I think the limiting factor in the engraving is the current, so allowing more current rather than more voltage (as used in the video) could increase the engraving depth/speed.

Thank you so much for doing this KoR! It's exactly what I was looking for. As for the nail polish, I am definitely going to try this for reverse etching by using the brush to make my design and then use this process to etch out the metal around it to wind up with something like a negative space frame around the prominent image or word. Thanks again!

Regarding the stains/splotches, you should probably polish the etching with some Autosol or other metal polishing product. As for stickers, there are some custom masks out there that people use for painting miniatures and the like. They should work just fine for this as well.

ive seen this done so many times on youtube, but this video was so clear about what you need how to go about it. Seems like such a simple process now

Man I miss when TKOR was like this and not just unending "experiments" of throwing stuff into a cotton candy machine.

Hi Nate, I believe the reactions going on are something like this: Fe(steel) + 3 NaCl(salt)+ 3H2O --> FeCl3 (iron(III) chloride) + 3 NaOH (sodiumhydroxide) + 3 H2 (hydrogen gas) So the gas developing is hydrogen and the greyish-black substance on the q-tip is probably the iron(III)cloride, which is dark-grey when in pure form and yellowish-brown when dissolved in water. Hope it helped

Seems plausible, though I'm not especially familiar with this reaction. It would be interesting to know if you could avoid the greenish stain if you used a different solution rather than NaCl. The hydrated form of FeF3 is pink which might look quite nice, although I'm generally hesitant to experiment with fluorine compounds.

I did the nail polish technique about 2 years ago. I used gel nail polish over small vinyl letters. When the nail polish was almost dry I used a razor to pick at a corner and peel up the vinyl lettering. After that I allowed the nail polish to completely dry and proceeded with etching. I used it on brass, not sure if the metal types affect how nail polish sticks but it did come out much better.

You are so awesome, I love you guys. I make this part of every day. Thank you for such high quality movies
