Could brick acid be used for etching as that is easily available and pretty cheap ? |

Maybe because it's diluted, or I didn't notice -- even after a couple of mistaken overnight cleanings in it. It also seems to work well to clean scale off of brazing and copper based parts that I've tried. But again, i didn't notice it eating away the base metal. It will really tear into zinc, though! |

I forgot -- I have done electrochemical etching of steel -- to make reed valves for pulsejet engines. Maybe that's a possibility. But i think there'd be some undercutting of the letters if you went anywhere near as deep as Rob has..... |
