Using no glue, position ribs 2,3, and 4 in place over-
plan.
Position notched T.E. on T.E. sheeting, align at wing
center. IMPORTANT: the T.E. has a 1/8” wide notch at one end-
match this notch with rib 2.
Starting with rib 2, press ribs into their respective T.E.
notches. Pin T.E. in place.
10.
Glue ribs 2,3, and 4 to bottom sheeting, main spar,
and T.E. (when gluing rib 2, tilt it very slightly using the set-
back gauge as shown).
11.
Lay parts out as shown. Glue rib doubler 6a to rib 6,
make one left and one right rib 6. IMPORTANT: when
installing rib 6 in next step, position rib so doubler 6a faces out
toward wingtip!
12.
Working one at a time, glue remaining ribs 5 and 6 to
main and L.E. spars and T.E. (do not glue L.E. sheeting at this
time!). Hold each rib up straight as it dries.
Glue T.E. and T.E. sheeting.
13.
Position set-back gauge touching bottom main spar.
Touch end of top spar to gauge, and set spar in rib slots. Glue
top spar to all ribs.
14.
Install top L.E. spar in same manner and glue.
15.
At locations shown on plan, glue two strut mounting
plates in place., Rear plate is glued directly over T.E. sheeting
(for short wing-move mounts one rib bay inboard as indicated
on plan).
Drill a 1/16” hole through each mount at punch mark
location.
16.
Position L.E. dowel, butting it against rib 6a and
checking it to be flush with rib No. 2. If the dowel in your kit is
over length, trim it to fit as shown below. Roll your knife over
the dowel in gradually deepening cuts.
Working a few ribs at a time, apply CA to glue ribs to
L.E. Gently squeeze L.E. into ribs and hold until set. Repeat
until all ribs are glued to L.E.
17.
Slide an aileron under L.E. sheeting to raise it in
contact with ribs. Only the rear half of the sheeting will be
touching the ribs. At this time glue only that portion of sheet-
ing in contact with the ribs. Move aileron on down the wing as
you go. Note: Instant CA is recommended here, since being
watery thin, a drop readily flows into the tight fitted joints and
dries instantly.
18.
Working a few ribs at a time, carefully pull the
remaining sheeting up against the L.E. dowel and glue in place.
Using CA, go back and reglue L.E. spar and all ribs
securely to sheeting.
