Part 1    An introduction to Scalescenes modelling    Tools you will need    Cutting straight lines accurately, cutting out window openings    Folding texture papers around window openings   There can be few British railway modellers who havent heard of the Scalescenes range of models based around the deceptively simple idea of downloading printable coloured files from the Internet, sticking them to cardboard and then assembling them to produce realistic, durable models. The brainchild of Graphic Designer John Wiffen, the Scalescenes range isnt limited to railway buildings from a modern container ship and dock crane and a to unload it, to bridges and cinemas, there is something for everybody in 0. H0 and N gauge. The range also includes various brick and stone covered papers for scratch builders. Legal Environment Of Business 8Th Edition Cross And Miller. Two free model buildings are offered, a small warehouse and a line side store building, Id certainly recommend building one of these models before beginning a more involved project. To get started, go to the Scalescenes site, click download where appropriate, and youll see a screen asking you to Save or Open the file. Click  Save and a zipped file will be downloaded to your computer. This file contains two tightly packed bundles of easily. It contains two PDF files, one full of instructions, and one containing the coloured printable sheets, with all the information needed to build the model in question. The instruction sheets need not be printed if you can work beside your computer. The techniques employed in all Scalescenes models are simple, either sticking a printed paper sheet to piece of card and then cutting out the components, or wrapping a piece of printed paper around a component made from several layers of card. Thin card and paper is scored to allow accurate bending to a given line, the when and hows are explained appropriately in the instruction files as shown below. In the terraced house model below, I have used an Epson ink jet printer set to the Text and Image Epson Vivid setting to print onto ordinary home office inkjet paper. Materials Broadly speaking, youll need thick card and medium card, printer paper, a glue stick, and P. V. A. glue such as Evostick Resin W. Id also recommend using a Fine Tip applicator with your P. V. A., as I wouldnt be without mine. The instruction sheet gives suggestions for the correct thickness of card dependant on the scale in which you are working in 0. I use 1. 5mm 2mm grey pasteboard available from art shops, together with packaging cardboard and cornflake packets as the medium card. Picture framing shops are another good source of card often off cuts can be obtained quite cheaply. Tools  I use a pointed device I call a stiletto, A which is a smoothly pointed device like a dart, for scoring card and paper prior to folding or bending, and for pricking holes in card on the cut lines and corners, and two knives. B is an ordinary craft knife and C a small Stanley snap off knife, with which you can always have a new sharp edge when you need one. A cutting mat, preferably A3 size will improve the quality of each cut and extend the life of your knife blades. I consider a wallpaper seam roller to be indispensable. This inexpensive item will roll out bubbles and creases from glued printed papers without fear of smudging or tearing them and will also ensure that wrapped paper components are finished with sharp clean corners, vital to achieve a realistic finish. Where by necessity a raw edge of card or paper is left visible, colour it to match the surroundings with a felt tip pen or watercolours. I have found grey, black and chestnut brown watercolour pencils are all I need for most work. A 1mm waterproof fibre tip artists pen is very useful,  I use one, for example, to draw a black line underneath a windowsill to give a greater impression of thickness. Here are two examples of Scalescene buildings, the TOO8 Low relief Terrace Backs and the TOO1. Country Pub, which I will refer to in the following pagesCutting to the line and cutting out windows the twin foundations of card modelling  To cut card accurately to a straight line first insert the tip of a blade firmly into one end of the line and slide a straightedge against the blade, aligning it with the rest of the line, just leaving the far end of the line visible. Now insert the blade tip in the far end of the line and swing the far end of the rule against the blade. Lightly run the blade along the line and if you feel for the blade dropping into the pierced card at both ends then the straightedge will be perfectly aligned and ready to guide the cut. Cutting to a curved line can be more difficult but often the use of an empty ballpoint pen tip can leave a gutter to guide the tip of a blade during its first light pass across the card. Window openings must look square and cut cleanly if they are not to detract from the overall appearance of a model. With a little practice and the use of a stiletto and sharp blade this is easily achieved. Pierce a hole at each corner of the window opening, insert the tip of a knife blade into a hole, and slide a straightedge up to the blade so that it aligns with the desired cut line. Then check that the blade will fit in the other hole too. Adjust the straightedge as necessary. Run the blade very lightly along the cut line and feel for the tiny clunk as it runs in and out of each hole. This will ensure that the straightedge is in the correct position, and that the holes will help you start and stop the cut at the correct point as you cut through the card using repeated light strokes. After an opening has been made, rub firmly or burnish its perimeter with the knife handle or other suitable tool to press down the sharp edge raised during the cutting process. Later, this edge could tear soft, gluey paper as it is folded around the opening. Scoring prior to bending  Scoring a piece of paper will allow it to be bent cleanly by partly severing the fibres on one side of the material, preferably on the back or inside face. Scalescenes models indicate a score line with a blue dotted line, necessarily on the printed side of the paper and scoring this side results in a white line on dark coloured components. Moreover, on light colours when weathered with powders or watercolour, the score line can show up clearly as it absorbs more of the weathering treatment than the surrounding material. To avoid these problems, prick through the score lines from the printed side, turn the paper over and having aligned a straightedge to the prick marks, score the back of the paper.
