As I have slight phobia of etching and strong acids in general, I think I'll give this a try :)
@adrian: where do I get the right knife? Where would one get copper sheets?
knife: http://de.y-o-w.com/suchergebnisse/q?filter=true&FVkeyword=Schleppmesser+kle... if the copper sheet does not have a carrier foil, then you must use the big carrier-sheet (slightly sticky) stored under the machine - otherwise you will harm the machine and destroy your knife. the knife should only cut through the material, never through the carrier. conrad has only some infeasible small pieces: http://www.conrad.at/ce/de/product/529532/PB-Fastener-Selbstklebende-Kupferf... ad etching acids: I've worked with sodiumpersulfate for etching quite a lot a few years ago and it never did harm to my bare hands, if you wash it off after contact. it will however leave stains in you clothing, so wear a lab coat. adrian
