Joining The Wing Halves; Installing The Dihedral Brace - Phoenix Model Cap 232 Instruction Manual

Instruction Manual

INSTALLING THE DIHEDRAL BRACE

1. Look carefully at the surface of each root rib on
both wing halves. Notice how the excess
covering material overlaps onto them. Using a
modeling knife, carefully cut out away the
covering from both root ribs. Iron the covering
down so that it does not pull away from the ribs.
!
It is important that the excess covering be
removed from the root ribs. This will ensure an
adequate wood to wood glue joint.
2. Using a ruler and a pen, locate and mark the
center line of the dihedral brace. Draw the
vertical line at this location on each side of the
brace.
Draw a center Line
3. Test fit the dihedral brace into the carton tube in
each wing half. The brace should slide into each
wing half up to the center line. If it does not,
remove the brace and lightly sand the edges
and tips until the proper fit is obtained.
4. Test fit both of the wing halves together with the
dihedral brace temporarily installed. Do not glue
it in at this time! The wing halves should fit
together tight with little or no gaps in the center
section joint. If the center section 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 with the dihedral brace
installed again. Repeat until you are satisfied
with the fit of the wing halves. The proper
dihedral is built into the two root ribs and should
not be altered.
5. When satisfied with the fit of the wing halves,
remove the wing halves and the dihedral brace.

JOINING THE WING HALVES

1. Mix a generous amount of 30 minute epoxy.
Working with only one wing half for now, apply
a thin layer of epoxy inside the carton tube and
to only half of the dihedral brace. Make sure to
cover the dihedral brace top and bottom as well
as the sides, and use enough epoxy to fill any
gaps.

2. Slide the dihedral brace into the carton tube up
to the center line. Remove any excess epoxy
before it dries using a paper towel and rubbing
alcohol. Allow the epoxy to cure before
proceeding.
3. Once the epoxy has cured, trial fit both wing
halves together to double check that the wing
halves still fit correctly.
4. Mix a generous amount of 30 minute epoxy.
Apply a thin layer of epoxy to the exposed half
of the dihedral brace, the inside of the carton
tube and the entire surface of both root ribs.
Make sure to use enough epoxy to fill any
gaps.
5. Slide the two wing halves together and carefully
align them at the leading and trailing edges.
Wipe away any excess epoxy using a paper
towel and rubbing alcohol. Use masking tape to
hold the two wing halves in place until the
epoxy cures.

6. When the epoxy has fully cured, double check
the center section joint. If any gaps are present,
mix a small amount of 30 minute epoxy and
carefully fill any remaining gaps. Remove the
excess epoxy using a paper towel and rubbing
alcohol. Allow the epoxy to fully cure before
proceeding.
7. Apply the trim tape to the center section of the
wings where they join.
