7)
Install the former cage on the inboard side of one of the
completed fuselage sides. The inboard side is the doubler
side. Ensure the pylon support is towards the bottom of
the fuselage. Before gluing the formers in place, ensure
the former tabs are fully seated in the slots and use a
square to ensure that F1 and F2 are perpendicular to the
fuselage side. Use thin 'CA' glue. Do not glue the pylon
support yet.
8)
The other fuselage side is glued on next. Align the
former cage on top of the remaining side and ensure the
former tabs are fully seated in the slots. Before gluing
with thin 'CA' glue make sure the fuselage is square in all
directions. Do not glue the lower pylon support in place
yet.
9)
The 1/4” plywood firewall is glued in place using 15
minute epoxy. Be sure to keep the fuselage assembly
square while the glue cures. Note that it fits into the space
formed where the plywood doublers end. Align the
firewall with the top of the fuselage sides. It will extend
slightly below the bottom of the fuselage and will be
sanded flush with the landing gear mount in a later step.
When the firewall glue has cured, epoxy the 1/4” plywood
landing gear mount in place. Note that it fits into the
notches cut out of the 1/16” plywood doublers. When the
epoxy cures for the firewall and landing gear mount, sand
off any 'squeezed out' epoxy and the lower edge of the firewall flush with the landing gear mount so that the
1/8” lite-ply wire trap will lie flush with the sides. Note that this picture shows both the firewall and landing
gear mount glued in place. It is recommended that each piece be glued in place separately, firewall first then the
landing gear mount.
IMPORTANT NOTE:
see step 24 on page 12 before gluing the firewall in place. It will be
easier to drill the air cooling inlet holes in the firewall before it is glued in place.
