The use of the coloured fiddleyard backscene works on this layout because of the sharp approach curve, which are sub radius 1.

I find the 'tester' pots of household paints very handy for this sort of thing.  Farrow & Ball do a wide range of colours in good opaque and tough paint - find them at Homebase etc.

Afraid I have no expertise on building weirs but, perhaps, a piece of translucent polythene to make the main curve of the flow, backed with some crinkled aluminium foil might produce the effect, especially if lit by an LED from below.  Just a thought - I haven't actually tried it.

One of the most difficult tasks I have found in modelling is sticking two different types of plastic together. I have found that a thin piece of styrene sheet acts as a buffer, and different adhesives an be used on each side, provided that they don't attack it.

You might find this a useful technique when you start working on the weir, when you will require to stick styrene to the surface of the perspex that you have used for the water surface.

I will be visiting Mid Wales, tomorrow Thursday and time permitting I will take some photographs of the mountains in the area, to use when producing the backscene. These images will the be printed out using a inkjet printer and then glued onto the fixed backscene. I intend to extend this with a extension piece when the layout used.

Sorry to hear about your problems with the backscene, I must admit I use tester pots a lot from the local DIY stores as they are very reasonable and can be used for many other modelling jobs.

I always tend to use vry thin fine grain plywood for backscenes as I find the paint sticks to this a lot better, but the experiments I have made with MDF have worked well especially if you gently rub the surface with some fine sandpaper to remove a substance that is sometimes sprayed on the sheets at the production mill.

I was given this tip by my local wood merchant

Keep up the good work, its looking good
