Objectives of this task:
In this task you will fit the bottom and back of the rear seat into place and fill the cavity under
the seat bottom with expandable foam to provide rigidity.
Materials required:
Epoxy resin and flock
Expandable foam - included in the kit:
Fit the seat bottom
Start by test fitting the seat bottom as shown below – it may be necessary to sand or cut to fit
in some places. Once the seat bottom fits firmly into place, tape or hold it in place and then
drill 3/32” holes and fit 6G self-tapping screws at ~50mm centres around the entire outside
edge, through the fuselage. Start by fitting a screw at each corner then add the screws each
side of the longitudinal rib then fit the remaining screws until the bottom is secured all round.
Mark the fuselage around the edge of the seat bottom and remove the bottom. Remove the red
peel cloth from under the seat, then sand around inside the mark and also sand the edge and
under the seat bottom then mix a batch of resin and coat both surfaces to be bonded.
Mix some flock into the remaining resin and apply a 2mm coat right around the marked area
on the fuselage and then fit the seat bottom into place and secure with the 6G screws and
leave overnight to cure. Next day remove the screws, heating them first if necessary.
Remove the red peel cloth and sand around the edges of the join between the seat bottom and
the fuselage and sand around the join. Mix a batch of resin and coat the surface and then brush
on 2 layers of 2” wide glass fibre tape right around the join. Leave overnight to cure.
