The next step with the baseboard was to add fascia panels to protect the foam-core board, which although surprisingly strong is not very robust. Joshua also wanted a back-scene and a lighting pelmet, for such a small layout it made sense to make them integral. The whole lot was cut from a sheet of 3mm MDF; the end pieces forming a support for the backscene and lighting, with a "lid" on top to cover the lighting. The front, rear, and end pieces were glued to the foarm-core board and also screwed to the blocks that had been set in the corners. Small strips of wood were used to help join the backscene to the ends, and blocks behind the lighting pelmet joined the top pieces together.
As you can see at this point track-laying had already started, as we'd realised it would be easier to lay the curve through the backscene and the point control wires before the backscene was in place. The curve is pretty tight, so the rails were slid out of the sleepers and pre-bent between fingers, before re-threading the sleepers back on. Track is glued down with PVA, held with a few track pins pushed into the foam-core until the glue has dried.
Point operation is by wire-in-tube, which was laid into a groove cut into the top of the foam-core board and held with hot glue. We've used the simple but effective trick of connecting the wire to a slide switch, which deals with frog polarity.
