Homemade Photoetch (again)

And now for something completely different. Homemade photoetch!! Not very fine I must say but enough for most of my 1/35 projects. it's been 5 years i am doing some now and I must say i have been streamlining it quite efficiently. The process is too long to be explained like that, but the first picture shows an insulated metal plaque.

The second one actually shows a trick: to dip it a few seconds in the etching tank, all the drawings must be really visible, if they aren't, you have to dip it again in the revealing acid!

And after an hour or so you get Rhine-gold..

So what was it for? Well some tiles on the floor, some letterings for a poster, some metallic round plaques for an electric device..
