Subject: Photo-etching brass

Would anyone be able to offer advice on photo-etching brass sheet for 
model making? I want to produce HO scale carriage sides, preferably using 
this technique, and using AutoCAD to produce the masks.

Any advice on reagents, mask design, limitations of the process (or 
alternatives) or even on reference books would be appreciated.

Many thanks,

Lachie,

Check out the 2mm Scale Association's picture gallery webpage at

http://phoenix.bath.ac.uk/~justinw/two_mm/

It includes an article I've written on my home photoetching setup. Sometime 
after the first of the year, I will have my own webpage with an updated article 
including a new etching tank, and the first results with a UV lamp exposure 
unit made from a Think & Tinker kit.

Good luck with your effort.

Randy

I bought the Home Etching kit from AutoEtch in PA. (advertised in Model
Railroader - I have the details if you cant find).

They supply a tank that heats Ferric Chloride and aerates it. Works ok.
The best thing they provide however is supplies of brass and nickel
silver sheet already precoated with photosensitive resist. 

The instructions in the kit are very good, and you can do a good job
straight out of the box. I have made some improvements, which I can talk
about later if you want.

The sheet sizes are 6" by 8" which is fine for my 1:120 modelling.
