You can add sodium hydroxide to brake it down into a liquid of a low pH and a sludge, the liquid can be disposed of in the drain and the sludge has to go to the local authority hazardous waste bin. Thats the other thing doing home etching- one is using hazardous stuff, also the etching process gives off hydrogen gas, not huge amounts but best to have a window open! Eoin

For one or two off items it is best to go to a suppler, there is a steep learning curve to home etching and it takes a lot of trial n error to get it right. This publication is a great introduction;- Most of the materials are inexpensive, except for the UV light box which is required for exposing/transferring the artwork to the resist on the metal to be etched. If one is considering this, stay away from the spray on resist available in the electronic stores which is rather hard to control. Using a film like 'Puretch' is far better and will help to keep your sanity! Eoin

The August Fair Date;-

July's Fair Date;-

It's a solder up job, parts from the etch sheets, the bottom sheet in the above photos is the main chassis frame, bogies frames are also on the etch sheets. Eoin.

Purchased many years ago when they were offered, discussed many times over the intervening years and now, and now!.......... Eoin

It's just unreal, poor girl

I'm assisting a chap to build one of these kits, thought I'd throw up a few photos here as wrennie's photos above, have disappeared;- Eoin
