Step 1 - Wing Assembly (wing tip)
Locate one WS3 from BP5, one
WS4 from BP8, and one WS5
and WS6 from BP7.
These are glued together, one
at a time to form the wing tip.
Start by pinning WS4 in place,
then glue WS5 to WS4 and pin
it in place. Now do the same for WS6, and finally WS3.
n n
Step 2 - Wing Assembly (lower spar)
Locate one of the 1/8" x 1/4"
basswood sticks, as this will
be used as the lower spar.
Measure and cut it to length
- making sure it extends from
the inside of the wing tip you
just created to beyond the root R3 rib by roughly a 1/4" or so.
Using a few drops of medium CA glue, tack this spar to the waxed
paper as shown, and to the wing tip, making sure it is straight along
it's entire length - or you can use pins in a criss-cross manner as
shown in the photo.
n n
Step 3 - Wing Assembly (WS1)
Now two WS1s from BP10. These
are used to form the lower, leading
edge sheeting.
Note they have straight and
tapered ends. Glue one of the
straight ends to the wing tip (WS4)
and pin it in position, making sure
WS1 is straight and true with the plans.
Now the second WS1 is glued to the first WS1, already place on the
board. This time the tapered ends will be glued together forming
a scarf joint. Again, pin this in place, making sure it's straight and
true with the plans.

Step 4 - Wing Assembly (R9, SW5)
Locate one R9 from BP3 and
one SW5 from BP8. Note that
SW5 is tapered and has a
circle etched in it. This circle
indicates the top and outer
edges of SW5.
Glue SW5 into the pre-cut slot
in R9 as shown here - making
sure you pay attention to their orientations.
As you'll do with all of the following steps, make sure that each tab
in an SW piece is fully inserted into each rib's slot as the glue cures.
Any gaps will add up over the length of the wing and make is so
the rib alignment with the plans keeps getting worse and worse.
n n
Step 5 - Wing Assembly (R9)
Now glue the R9 assembly in place,
as shown here. Make sure that it is
properly aligned with the plans and
that it is completely flat on the plans
as the glue cures.
Also glue the bottom edge of SW5 to
the lower spar.
n n
Step 6 - Wing Assembly (WS7, WS8)
Locate one WS7 from BP7 and one WS8
from BP8.
Remove the pins from the pieces that
make up the wing tip, as these two parts
will be glued on top of the tip pieces
already in place, strengthening them.
First, glue WS7 over the outer portion
of the wingtip, and so the ends butt up
against the R9 rib.
Then glue WS8 on the rear of the wing
tip, between the R9 rib and R8 rib (R8 not yet in place).
n n
Step 7 - Wing Assembly (R8)
Locate one R8 from BP3. It
is glued in place, making
sure the tab from SW5 is fully
inserted, and that the rib is
perfectly flat on the plans.
n n
Step 8 - Wing Assembly (R6, SW4)
Now using the same
techniques, locate one R6
rib from BP1 or BP2, and two
SW4s from BP6.
Note the SW4s are tapered
and have a circle etched in
them. This circle indicates the
top and outer edges of SW4.
Dry fit them first, then when
satisfied with how these
pieces fit, glue them in place, making sure they're aligned and all
tabs are properly seated. The bottom edges of the SW4s should
be glued to the sides of the lower spar and the rib should be flat
against the plans.
n n
Step 9 - Wing Assembly (WS9)
Locate one WS9 from BP8. Glue
this in place between over the
rear of the wing tip, between the
R8 and R6 ribs.
n n
Step 10 - Wing Assembly (R6, SW3)
Locate another R6 from BP1
or BP2, and two SW3s from
BP5 or BP6.
Dry fit them first, then when
satisfied with how they fit,
glue them in place, making
sure they're aligned, all tabs
are properly seated and the
rib is pushed flat against the
plans.
