18) Working with the right wing half for now,
test fit the dihedral brace into the plywood box in
the root rib. The brace should slide into the wing up
to the centerline. If it does not, remove the brace
and lightly sand the edges and tips until the proper
fit is obtained.
The dihedral brace is cut in the shape of a "V".
The "V" shape should face the top surface of
the wing (curved surface) when the brace is installed.
q
19) When satisfied with the fit of the dihedral
brace, remove it from the wing half.
q
20) Mix a generous amount of Kwik Bond 5
Minute Epoxy. Apply a thin layer of epoxy inside
the plywood dihedral brace box and to only half of
the dihedral brace. Make sure to cover the top and
bottom as well as the sides, and use enough epoxy to
fill any gaps.
q
21) Slide the dihedral brace into the plywood
box up to the centerline. Remove any excess epoxy
before it dries using a paper towel and rubbing alco-
hol. Allow the epoxy to cure before proceeding.
q
22) Test fit the two wing halves together. With
the inboard panel of the left wing half flat on your
workbench, the joint in the right wing half should be
1-3/4” off the surface of the workbench. This mea-
surement should be taken at the trailing edge where
the outboard and inboard panels were joined. Use
books or a scrap piece of wood to hold the wing half
in the proper position. It is also helpful to weight
down the left wing half so it does not move. See
figure # 3 below.
Figure # 3
The wing halves should fit together tight with
little or no gaps in the joint. If the joint is not
tight, remove the wing halves and lightly sand the
edges and tips of the dihedral brace. Test fit the wing
halves together once more. Repeat this until you are
satisfied with the fit.
q
23) Mix a generous amount of Kwik Bond 5
Minute Epoxy. Apply a thin layer of epoxy to the
exposed half of the dihedral brace, the inside of the
plywood box in the root rib and the entire surface of
both root ribs. Make sure to use enough epoxy to fill
any gaps.
q
24) Slide the two wing halves together and care-
fully align them at the leading and trailing edges.
Align the wing halves as done in step # 22, keeping
the inboard panel flat and using a book or scrap wood
to hold the right wing half at the proper height. Wipe
away any excess epoxy using a paper towel and rub-
bing alcohol and allow the epoxy to fully cure before
handling the wing.
q
25) When the epoxy has fully cured, double
check all three wing joints. If any gaps are present,
mix a small amount of Kwik Bond 5 Minute Epoxy
and carefully fill any remaining gaps. Remove the
excess epoxy using a paper towel and rubbing alco-
hol and allow the epoxy to fully cure.
INSTALLING THE STRIPING TAPE
q
26) Using a modeling knife, cut the white self
adhesive trim tape into three 9” long pieces.
q
27) Turn the wing upside down. Remove the
paper backing from the trim tape and carefully apply
the tape over the three joints on the bottom of the
wing. Begin at the leading edge and carefully work
back to the trailing edge. Use a modeling knife to
remove the excess trim tape.
q
28) Turn the wing right side up. Remove the
paper backing from the blue trim tape and carefully
apply the tape over the two outboard joints on top of
the wing. Begin at the leading edge and carefully
work back toward the trailing edge. Use a modeling
to remove the excess material from the leading and
trailing edges.
q
29) Remove the paper backing from the red and
white piece of trim tape and carefully apply the tape
over the center section joint on top of the wing. Be-
gin at the leading edge and carefully work back to-
ward the trailing edge, aligning the red on the tape
with the red on the wing. Use a modeling to remove
the excess material from the leading and trailing edges.
