  1. Should hold the terminal in place for a set amount of time. Ive always found about 10 seconds is best. Hold in one place the move to the next like a series of dots.

  2. One thing I read was to dissolve as much salt in the water as it will hold. At one point it stops dissolving

  3. To blacken what you etched you need to use AC not DC. Just rig up a simple DPDT switch by modding the wall adapter to switch between the two.

  4. Your 12v converter has a symbol on it that shows pos. and neg. – —–(0—– + Looks kinda like that and it means the outside wrap of your coaxial is the ground.

  5. What would happen if you use the home energy (230 v in germany in the usa i dont know) to etch iron?
    would it just completely melt?

  6. You are suppose to leave the Qtip in one spot for 10 seconds at a time. For vinegar to work. You have to soak the steel in the vinegar for a few minutes

  7. needed way more salt. The reason I am saying that is because I watched someone do something similar just before this video and they used a different mixture. They used a mix of salt with a little water in it instead of lots of water with a little salt in it. The engraving they did was much deeper and the conductor they used to apply the electricity to the engraved surface was an iron or steel rod with a clip attached to it with another attached to the steel plate.

  8. @kingofrandom revisit this experiment, but with apple cider vinegar instead the acidity is higher and might work better than regular vinegar

  9. Instead of a stainless coffee mug (303 grade) would tool steel be better (07 grade or 317L grade), 303 is naturally magnetized where tool steel is not? (Your wrench would be example of 07 grade, a stainless bolt or nut would be an example of 316L)

  10. Clean the metal with acetone before sanding. You'll have better luck with getting paint/nail polish to adhere properly.

  11. Can we use two 12v adapters so it will be 24v out put 2amp. ? Is it possible anyone can reply for this.

  12. you need to abrade the substrate in order for any coating to "stick" to it. IE sandblasting, wire wheel, grinding disc, coarse sand paper etc

  13. Do a timelapse of how long it takes to etch all the way through a piece of metal and a different type of materials. And see what will happen if you use lot of voltage

  14. Did you have a best procedure to remove those stains left in the steel?

    Hoping for a response 🙁 please need to know

  15. Yeah the more power than better and you know why salt works so well and it turns into an acid as it’s electrified that and it’s also an excellent conductivity

  16. I like your tape idea it sticks better because it said he sieve and it also holds up under alcohol because alcohol breaks down it he sieve due to the Acid and rubbing alcohol would definitely pretty much clear off nail polish

  17. Be careful with advertised Butt Wipes; they are not really flushable and can clog up your sewer pipes, making life stinky.

  18. I wonder if you could get a better finish if you coat the cup completely and then cut out the design you want, and instead of using a q-tip to etch, you just electrolized a solution and dipped the cup.

  19. You can also mask the area off with a raised lip to submerge the etching in vinegar & inserting the negative lead attached to a penny. It will give it an even gold tone. HOWEVER !! Don't allow the penny to touch the steel because it will concentrate & ruin the etch.

  20. Electroplating with a gold ring as a source will fill the areas that were yellows part of the crown. Copper will plate also!

  21. I know I’m really late, but the trick to use nail polish as a mask is to only apply a thin layer of it, the more you apply the easier it peels off

  22. This method is called electrolysis, I use copper sulfate if I want to engrave copper, and if I want to engrave aluminum I use aluminum sulfate. As the polish I use engraving polish from graphic chemical or I make it dissolving chapopote and turpentine

  23. The venegar is used with salt also. There is not chrrent flowing. You could have checked with an amp meter to see if you need more current o more voltage
