and the R6-R10 to the right side of the middle jig.
Now, snap the dowels on to the jig supports. Then carefully space
the ribs apart, to their proper locations as shown in the photo.
Step 7 - Wing Assembly (R10 & SW9)
Locate one SW9 from
BP11. Note that this has an
engraved circle, as do all of
the sheer web pieces. This
circle designates the top and
should also be positioned
towards the root rib (R1).
Glue SW9 to R10, making
sure SW9's tab is completely pushed into the corresponding slot in
R10. Also make sure the outer edge of SW9 contacts R10 along it's
entire height. Hold this away from the J2 jig until the glue cures.
Once cured, then push R10 against J2.
To help hold R10 (and any of
the other ribs) in place, there's
a bunch of J8's cut into LP1.
Wick thin C/A into any of
these you use first, then snap
them on to the dowel and use
them as a "stop".
Step 8 - Wing Assembly (SW3-SW8)
Locate one set of
SW3-SW8 sheer
webs from BP13.
Starting with R9,
you will attach
each of the
appropriate SW
pieces (as noted
on the plans)
and glue them
together as shown
here. You can
either do one at a time, or position everything in place, then glue
everything together at once.
Regardless of how you do it, make sure all of the SW circles are
positioned properly and their tabs are completely inserted into the
each rib's tab cutout before gluing. Also make sure that ribs are
aligned to the plan (remember to use the triangles we talked about
in step 1).
Even small errors here can multiply as you go along the wing and
causing larger and larger misalignments as you move further along
the wing.
Step 9 - Wing Assembly (SW2)
Locate two SW2s from LP1
and LP2. These are installed
the same way as the previous
SW pieces, just doing it twice.
You are paying attention
to where those etched SW
circles are, right?
Also - take care not to get any extra glue in the space between the
SW2 pieces (and the SW1s in the following steps). Any extra will
have to be filed away later on when fitting the dihedral brace, keep
this area as clean as possible.
Step 10 - Wing Assembly (SW1)
Locate two SW1s from LP2.
These are installed slightly
differently as they are only
glued to R2 at this time. You
can push them into R1 to help
position them, but don't glue
them to R1. Don't do it. Trust
me - it's better this way.
Step 11 - Wing Assembly (WH1 & WH2)
Locate one WH1 and one
WH2 from LP1. These have
circles as well, showing
upright and the edge that will
be against R1. Glue these in
position to R2, but again - not
to R1. Trust me - this will all
make sense in a couple more
steps.
Step 12 - Wing Assembly (WH3 & WH4)
Locate one WH3 and one WH4 from LP1. These also have circles
and you should know the drill by now. Pay attention to the
orientation, then glue them to R2, but not R1.
Step 13 - Wing Assembly (R1)
Back in step 1 I mentioned
the root rib triangle. Well,
now it's time to use it.
Take some time with this
step as you need everything
aligned, but also you
need R1 straight down
it's entire length.
Epoxy,
or slower curing glue is
recommended for this as
there are several pieces
being attached in succession.
Starting at the leading edge, start gluing and inserting the tabs
from the WH pieces the SWs and the remaining WH pieces into
R1. When they're all properly seated into R1, R1 should be at a 2°
angle. And you can verify this with the root triangle. Measure in
several places, all the way along it's length. And at the same time,
