I'll go chase down what Micromark sells in their kit, which specifically states it works with stainless. I doubt they sell stuff that needs a fume hood without warning people ahead of time. > Although, I did find a howto site where they just used a electrolyte.

It's possible that adding an electrical current to the flow would both accelerate the process and might even minimize undercutting. I did some research a while back on photoetching services, and found one that will etch from the front, the back, or both at the customer's option. They point out that this gives a profile to the etched object. I figured I'd etch from the back for nixie cathodes, so the front (facing the viewer) surface was the largest. Since we'd be etching pretty thin material, I doubt it would be a big problem. > Otherwise, if anybody would like to attempt etching, and would like a enchant > mask, and you live in the US, I'll be happy to whip one up on my vinyl cutter > and ship you one/several.

My first thought was that the vinyl adhesive is really tough, and would bend and tear the delicate metal, but then it occurred to me that there's probably a way to dissolve away the vinyl. I expect there are solvents out there that would do so while leaving metal untouched. - John -- You received this message because you are subscribed to the Google Groups "neonixie-l" group.
