LOKI VINK 4 Posted September 17, 2017 Share Posted September 17, 2017 thought id share my new knife I made with my Logo etched with salt water and a small electric gate motor battery.. etched real fast. anyone know how to make it etch a little smoother and slower.? 1 Link to post Share on other sites
Charles dP 479 Posted September 17, 2017 Share Posted September 17, 2017 Mooi mes man . Unfortunately I haven't done the etch yet. I was going to try it on my next knife. I do know that etching happens at different rates depending on the structure of the steel. If the area you've etched isn't uniformly hardened (being possibly on the edge of your heat and quench) you may get an uneven etch. Link to post Share on other sites
LOKI VINK 4 Posted September 17, 2017 Author Share Posted September 17, 2017 ag dankie man haha. jy van Suid Afrika af na Engeland toe getrek?. i also think the hardning process can effect the etch.. I used N690 stainless. Link to post Share on other sites
Charles dP 479 Posted September 17, 2017 Share Posted September 17, 2017 Hehe. Yeah, I came to the UK 16 years ago to see a bit of the world... then life happened . Link to post Share on other sites
Karim 62 Posted September 17, 2017 Share Posted September 17, 2017 So funny to read SA, puik messie trouwens. Great Job on the blade, you could consider using vinegar (no salt) if i recall correctly. Link to post Share on other sites
LOKI VINK 4 Posted September 17, 2017 Author Share Posted September 17, 2017 haha as far as i know im the only Afrikaans guy on this site. I know what you mean Charles. dank je Karim, il do vinegar next time on a test piece or use less salt in the water. Link to post Share on other sites
Brian Dougherty 1,175 Posted September 18, 2017 Share Posted September 18, 2017 Adding some resistance between your battery and the etching pad will slow the etch down. Just a few ohms will probably do. The back-yard anodizers used to use a tank of salt water as a resistor before adjustable power supplies became so affordable. Link to post Share on other sites
LOKI VINK 4 Posted September 18, 2017 Author Share Posted September 18, 2017 sure I can get a small resistor to do the job. thanx Brian Link to post Share on other sites
