10. Test fit the wing joiner into one wing panel, then the
other. Be certain the joiner is installed upright with the joiner
angled upward for wing dihedral. Also make sure that the
joiner slides in all the way to the centerline. Test fit the wing
panels together with the joiner. Make certain both panels
fit well.
❍
11. The measurement for this wing is 3-3/4" [95mm]
plus/minus 1/8" [3mm] from the top of your table to the
highest point of the wing tip as shown in the photo. To check
that this is correct, join the two wing panels together with the
joiner in place.
Lay the wing on a flat surface with one panel flat on your
bench or table. To do this you will need to allow the trailing
edge of the wing to overhang the edge of your table in order
to avoid the aileron torque rods as shown in the photograph
above. After making sure the root ribs are fitting together
with no gaps on the top or bottom of the wing, measure the
distance from the surface of the table to the wing tip. If this
measurement is not 3-3/4" [95mm] plus/minus 1/8" [3mm]
make adjustments in the plywood joiner. (It is possible that
the joiner may require slight sanding to remove slivers of
wood or excess epoxy that may interfere with the fit).
❍
12. Once satisfied with the fit of the joiner and the wing
has the proper dihedral, it is time to glue the two panels
together. First thoroughly coat the inside of both pockets
where the joiner fits and one half of the joiner with
30-minute epoxy. Making certain the joiner is upright, insert
the coated end into one of the wing panels. Coat the other
end of the joiner and both wing root ribs with the epoxy and
join the two wing panels together.
❍
13. Wipe away epoxy that squeezes out from between the
wing halves with paper towels saturated with alcohol. Use
masking tape on the top and bottom to hold the wing together
as shown. Be certain the root ribs on the ends of the wing
panels accurately align. Again, wipe away excess epoxy and do
not disturb the wing until the epoxy has fully hardened.
HOOK UP THE AILERONS
Do the left wing first so the assembly matches the
photographs the first time through. You can do one wing at
a time, or work on them together.
