Etch METAL with Battery Power

  1. HOOKED!!!
    Started with an experimental etch on a hip flask. Just sea salt in water, a cue tip and a 12 volt battery charger.
    Done my Leatherman, Zippo, belt buckle and cutlery.
    Have built a custom kit and getting a vinyl cutter, to save time.
    Everything is getting etched.
    Thank you!

  2. Have you tried to use low voltage . To remove rust from old tools. Or maybe I should just asked what is the best way to remove rust from old tools.

  3. I wonder if this would work with copper – might be a quick and easy way to etch PCBs without all the soaking / UV exposure / messing about with corrosive substances. Only 1 way to find out…

  4. Try without cuting the tape on the metal ans then you can confirm if the edge is the result of cuting or the etching metal .

  5. It doesn't matter which polarity you hook up. I've always done it like welding clamp the negative and use the positive with the same results

  6. Nail varnish and then use a cheap laser engraver to burn through with pretty high accuracy. Works a treat for logos on knives.

  7. 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.

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

  9. 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.

  10. 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.

  11. 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?

  12. 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

  13. 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.

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

  15. 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)

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

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

  18. 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

  19. 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

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

    Hoping for a response 🙁 please need to know

  21. 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

  22. 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

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

  24. 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.

  25. 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.
