Begin by laminating the two rear spars
together and then add the rear spar
doubler to that. Ensure that you get the
centers correct, draw a centerline if
necessary. Use CA or epoxy but make
sure of a good fit and ample adhesive.
You will need to use a piece of 1/8 balsa
or light ply to place outboard of the rear
spar doubler that makes the rear spar 3/8
thick all the way to the end. Sand flush
with the top and bottom of the spar
assembly.
Laminate the main spar doubler onto the
main spar in the same fashion and
ensure that it is centered properly.
Laminate the rear spar
from here out with
1/8
th
Balsa
Locate eight 6-32 t-nuts and press into
position in the formers named GPLATE.
Use epoxy or thick CA on the back of
the nut to keep from working loose.
Epoxy the main spar into position at the
front of the gear well of a foam wing
core. Make sure it is centered on the face
of the foam top and bottom as well as
left and right by aligning the center of
the ¼ x 1-inch slot with the root edge of
the core. The doubler of course faces the
interior of the wing.
Epoxy the rear spar assembly into
position in a similar fashion, top and
bottom and left and right using a
centerline that lines up with the root
edge of the core.
Laminate two the WR5s and glue into
position between the Main and Rear
Spars as well as formers WR4 and WR3.
