Preparation of the vacuum-moulded components
In all the drawings of vacuum-moulded parts the areas to be cut out or cut off are shown as
hatched-in areas. Please note that the halves of the seat backs 31 are moulded into the aft
part of the deck 27, which has to be removed as shown in the drawing D. The cabin support
flange 25 surrounds the cabin floor 30 in its moulding. These parts should be separated with
particular care. Parts 1, 25, 27, 28, 30, 31 and 32 are cut out using a fretsaw and balsa knife;
see drawings B, C and D. The cut edges are sanded smooth when the part concerned is
trimmed to fit.
