1 There is a good selection of short static grass fibres now available for ‘N’. Choose fibres from Noch and WW Scenics that are 2.5mm or shorter in length.
2 Static grass applicators come with different heads for different length fibres. Select the head with the mesh best suited to 2.5mm or shorter fibres. Then fill the applicator with fibres.
3 To plant the grass and weeds between the line and the road, I painted on Grass Glue with a round paintbrush.
4 Attach the alligator clip from the electrostatic grass planting tool to a rail (or a pin in the baseboard) to complete the electrical circuit.
5 Hold the electrostatic grass tool a few centimetres from the wet glue and shake it. The fibres will fall out and stand upright in the glue.
6 If you don’t have a static grass tool, you can purchase adhesive static grass tufts from various outlets including WW Scenics.
Secure the tiles with wood glue. Start from the bottom and complete an entire row before progressing. The row above should slightly overlap the row below.
I trimmed any tiles protruding over the edges of the roof former with a pair of scissors. Make sure that the scissors are sharp – blunt blades will pull and damage the roof tiles.
Form a rectangle, estimating the size in relation to your building’s roof – it needn’t be perfect. Lengths of balsa should then be arranged in a criss-cross pattern.
Cut rectangular holes in the roof former to allow the truss structure to show through beneath. Be aware that tiles will frame the edges of each hole
Score the central fold line using a sharp scalpel and a steel ruler as a guide. Although this aids folding, it does produce an unsightly gap, which will be covered up later.
Thinner lengths of balsa can be added to provide variation. You needn’t be overly precise regarding placement or, indeed, length at this stage – it’s a derelict building after all.
Measure the length and width of your building’s roof line. Add half a centimetre at either end to form a lip and mark your measurements onto a piece of thick card.
Cut out a batch of 1cm2 tiles – a paper cutter will speed up the process. I found Model Rail’s front cover to be the perfect thickness.
The roof truss arrangement was cut to size and glued to the inside of the card roof former using cyano glue.
Cut lengths of 0.5mm balsawood using a scalpel to form a roof truss arrangement. I used cyanoacrylate to secure the trusses, but wood glue would also work fine.
