Thread: Etching Questions & Ideas

Some people have managed to do some pretty decent etches on blades using things as simple as wax/nail varnish and ferric chloride or salt water and a battery. It's surprising what can be done with rudimentary tools. Not that I'd try it on a razor as the etch tends to spread as it gets below the surface using these slow techniques (giving you a dovetail sort of shape if you were to cut through the blade and look side on).

Okay Lou, I'll bite...

Just to let everyone know, I'm working on a 'secret' project and it does involve etching...not saying anymore, but I'll my first proto types are going to Lou, and I'll let him sing praises ...or tell of my folly, after all is said and done. Until then..suspence for the lot...
One thing I will say about laser etching is this. I remember reading about clear scales (I think the thread was started by Joshearl) and someone said that there are companies that will laser cut acrylic. maybe they can be coaxed into etching.
One thing I have been reading about is shallow etching takes AC current and deep etching takes DC, but one produces a black mark and the other a clear one.
