Thread: Acid Etching

Ramo, what are the sheets that are used to make circuit boards you are talking about, any idea on where you'd get them? thanks.

the sheets are press-n-peel just google it, you can find them in any radioshack, here's a how-to How To

this guy uses regular semigloss print paper, i've seen people using magazine covers for this purpose (printing circuit boards)
semigloss

the only diference betwen circuit boards and etching is that they dissolve the entire layer of cooper, you just want to mark it so time is what matters.

the two important thong are use a LASER printer not inkjet, and make a NEGATIVE of the design.

btw, the acid used in circuit boards is ferric cloride, but you can use any acid at hand, like battery acid muriatic, or even vinegar just consider the time-acidpower factor

I saw that site about six months ago. I emailed for more info on whether or not they thought their etch o matic would etch concave areas (hollow of a razor) and never received a response back.

Awesome, Ramo. Isn't open source sharing the best? Now we're all getting somewhere!

Now.......does anyone have any thoughts on what they think the best way would be to transfer the blade etch in the hollow of a blade to a paper in order to scan it in? There's the old time method of rubbing pencil over a paper placed on a surface, but that would take a bunch of monkeying in some photoshop type software to clean it up.

I've thought about coating the entire blade side with the etch in some sort of ink or indicator dye and then rubbing paper over that. The right ink and the etch would appear as white text/negative. Still, I don't know if that would be the best option either.

Let's keep this discussion going!

my geek might be showing by posting this but... here is a video showing you how to etch circuit boards and also how to laser print out a template and use transfer paper.

why don't you take a good close-up picture of the blade and post it, a friend is prety good in photoshop (she is graphic designer) and maybe she can help...

I used Word to generate the text that I need. The fonts took a little bit of tweaking to figure out, but since the etch that I want to replace is just text it was rather easy.

I need some sort of curved replacement for a flat hot iron. I've been thinking about laser printing on glossy paper as the way to go. Just need something hot and curvy to adhere the image to the blade.

I'm not sure I'm having the right mental image, but the 1st thing that comes to mind is a curling iron (I burned myself on one at my sisters house last weekend, so it's fresh on my mind).

That's exactly where I was stuck in thinking up a solution to this challenge, the hollow of the blade and then.........

Bubba! Great idea. My wife has a curling iron and I bet it would work.

Have a look at this: Knife Etching.

Though it does show different methods of etching I found the step by step layout quite helpful.

ok, some time ago i used a sheet of galvanised iron to bend wood, I used a jig based on a guitar making wood bending model i saqw on internet, you can make someting similar,, just match the radius of you razor hollownes...

I´m attachin a picture of the original guitar making jig, inside there are a couple of light bulbs (the real ones not the energy saving kind), just heat it and iron...
