Install the top spar flange SPF-T. Apply
glue to the top of the sheer webs from
W12 to the root and to each rib in the
flange notch at the top of each rib. Place
SPF-T onto the wing and use a straight
edge to weigh it down until it cures. Check
that the flange is in good contact with the
sheer webs along the entire length.
c
17 Locate and prepare the wing tip WT. In-
stall and glue WT to W12, FLE, the sheer
web assembly, FTE and TE.
c
18 Locate and prepare the trailing edge top
sheeting TES-T. Plane a small amount of
material off of the trailing edge to bring it
into contour with the trailing edge of the
ribs. Install and glue TES-T in place. As-
sure that it is bottomed in the notches.
Note the indentation at the root end. Re-
move any glue that squeezes out into this
area, as it will interfere with the center
sheeting when it is installed later.
c
19 Locate the cardboard cable tunnel tube
and cut one piece 6-3/8” long and another
9-3/8”long. Install the 9-3/8” section first
into the holes in the wing ribs. Push this
tube through until it just protrudes through
W7. Install the 6-3/8” tube until it just pro-
trudes through W3. Glue both tubes in
place.
c
20 Locate and prepare one top center sec-
tion sheeting TCS. Install and glue this
part. TCS should butt snugly up against
TES-T.
c
21 Locate and prepare the top leading edge
sheeting LES-T. Before we can install
LES-T we will need to sand the top of WT
to contour with W-12. Test fit LES-T and
sand WT until you gat a good fit. LES-T
will lay on top of the top wing spar flange
SPF-T and butt up against the ribs at the
aft edge of the spar flange. It should also
butt up against the center section sheet-
ing TCS.
