Moved from Rob's Forge thread as it was getting off the topic as pointed out :palm: Like we ever get side tracked.... Just had 5 mins whilst the wife is out, so etching the dogs bowl in the kitchen was a go. I used a 12v power supply salt water solution applied with cotton bud. I just grabbed some packing tape and a blade to make the mask. I got the polarity wrong so loaded the cotton bud with copper before I reversed polarity and forgot to change bud, hence the copper plate, might be useful in the future ? Clean up and buff with a Garryflex block. I really didn't know what result I was going to get so its nothing fancy. It really was so simple to do, with proper stencils I can see this being useful for marking tooling or even applying a surface finish. A new skill learn't.... Result :thumbup: p.s Just watch the chlorine fumes coming off. |

Hi Joules , was the dog impressed ? :lol: :lol: :lol: Good to see you gave it a try :thumbup: , vinyl art work would make a good mask . Are You going to develop the process ? I see your a fellow Garryflex user :dremel: , there great to have around the shop , I cut mine up to make all shapes and stick bits to lolly sticks . Cheers Rob PS I dont mined my thread going south :med: |

He wasn't chuffed as he thought he was going to get a bonus feed. He also looked somewhat suspicious of his Dad hooking his bowl upto cables :zap: As it happens I have a vinyl cutter on hand, so YES I will be trying some more fancy stuff and try etching with other acids, citric, vinegar and anything that is less likely to raise eyebrows as I dispose of it. I even tried a Sharpy to mask but the result was not as good as an etch resistant pen. |

Cheers for the link Rob, I have been playing with household acids with mixed results. Can't beat saltwater on steel for results. Could I be so cheeky to ask of you a master class in deep etching like you do with your name plates, they are just great and something I would like to do here. The above etch tests are on stainless steel using masking tape for the stencil. The J stencil lifted and got some pitting as I hovered the bud in the water. If you keep pressure on the tape with your damp cotton bud the etch doesn't creep under the edges as I thought it would. Literally I only kept the bud on for 3-4 seconds then moved along the mask, did this for a couple of minutes to get a deep etch. I used a Sharpie to highlight the etch as the above electric spark hardly shows on camera. Damp is better than wet, use a bit of stainless tig rod to apply current and pressure to the cotton bud, so you don't rot your croc clip. |
