D D 8. Make sure the ribs are fully down on the plan
and all ribs are inserted into the LE notches. Angle rib
W-1 slightly using the dihedral gauge (DG). Glue W-
1 to the TE, LE and bottom spar. Glue all other ribs to
the LE and bottom spar. Follow up by applying a drop
or two of medium or thick CA to all spar/rib joints.
D D 9. Glue the top spar in place, making sure you
do not change the angle of W-1. IMPORTANT:
Install the top spar with the short spar facing down.

D D 10. Sort through the pre-cut 3/32" balsa vertical
grain shear webs, selecting the hardest ones (which
will be used near the root of the wing). Glue the shear
webs to the rear edge of the spars in all rib bays
except between ribs W-1 and W-2. NOTE: You
may wish to trial fit, mark, and trim each web before
gluing in. NOTE: The webs must be securely glued
to the spars, but it is not necessary to glue the webs
to the ribs.
D D 11. Lightly sand the tops of the ribs to blend with
the notched trailing edge; then glue one of the 3/32" x
2" x 39-3/8" balsa trailing edge sheets in place.
NOTE: The edge of the TE sheet may not be exactly
straight, but just position the sheet so it slightly
overlaps the TE, and any overlap can be sanded off
later.
D D 12. Before applying the leading edge sheeting in
the next step, block up the leading edge in a few
places with scraps of wood. Then use your T-bar to
lightly sand off the edges of the shear webs and
smoothly blend the ribs to the spar. Also, lightly sand
the tops of the ribs to eliminate imperfections.
D D 13. Prepare the 3/32" balsa leading edge
sheeting by sanding the front edge to a slight bevel
so it will fit snugly against the back of the leading
edge.
NOTE: It will be helpful to have the following items
handy for the next step . . . thin CA, thick CA, a wet
cloth and masking tape. Read through the following
step and go through a "dry run" before actually gluing.
NOTE: In the next steps, maintain straightness by
keeping the wing down on the flat surface and on
the TE Jig.
D D 14. Position the leading edge sheeting at the
rear edge of the notched LE so there is an equal
