Griffon 2000TDX - 1/10 scale

Cut out the duct ring (H) from 3mm thick plywood. The inner edge must be cut accurately to ensure that a good joint will be made to the duct inner wall. The duct ring should be marked out into 24 sections as shown in the drawing.

Place the duct ring face down on a flat surface on top of a polythene sheet or bag. Fit the rolled and glued inner wall (Y) inside the ring. Run a PVA glue bead around the joint and leave to dry undisturbed.

The inner and outer walls should be 100mm wide, and long enough to wrap around the duct ring, with an overlap of 15mm.
