The backscene board was constructed by inserting 1” uprights at 600mm centres between the two L-girders at the rear of each level, then mounting 3mm masonite sheeting across the front. This was glued in place, and held with clamps until dry. This was a very slow process, as each 2.4m sheet required 8-12 clamps to provide the necessary pressure to keep it in place, and the clamps were left in place for at least 24hrs to allow the glue to dry.
This was especially important in the corner sections, where the long 2.4m sections gave nice sweeping corner curves on a 500mm radius, but created quite a bit of tension in the curved sheet until the glue had set. Despite having amassed a collection of some 24 clamps, the cutting, gluing and clamping process took a while to complete.
Once all of the backscene was installed, the masonite joins were filled, sanded, and the masonite covered with a coat of undercoat, before two topcoats of sky blue as a base for future designs was applied by roller, giving a very smooth flat finish.
