Back through the mists of time; well 1979 to be precise, the iconic Dovey Valley appeared in RM over two issues. One of these contained a method of constructing slate waste slab fencing using plastic sheet. This has been used by 009-ers ever since with a couple of slight variations and I’ve tried most of these. Here on the Peco epic Trefach, 20 thou black plasticard is the material. This has been given a coat of Humbrol 29 followed by coach roof grey. The latter unmixed to give some colour variation. Alternatives are to sand the plastic to break the surface to a grey or possibly to use card which was the method 25 years ago with Wood End. All have their pluses and minuses, but all fall into the ‘tedious, but worth the effort’ bracket of model making. I’ve done over 9′ of this on this project and still not finished yet.
