Dynaflite DYFA2016 - Manual (Page 22)

Q Q 9. Glue the 5/16" x 24" hardwood dowel
leading edge to the ribs. Use the dihedral gauge to
make sure rib #2 it is at the correct angle when you
glue the dowel to it.
Q Q 10. Glue the 1/8" x 1/8" x 24" outer
turbulator spars in the notches of the ribs. Use the
dihedral gauge to make sure rib #2 it is at the
correct angle when you glue the spars to it.
Q Q 11. Make six shear webs from the 1 /16" x 3"
x 24" balsa sheet to fit between the sets of ribs from
#2 out to #7. Cut or drill a 5/32" hole 7/16" from
the bottom of the web where the aileron cable guide
tube passes through.
LJ LJ 15. Use your bar sander to angle the end of
the 5/8" x 1 -3/4" x 24" balsa trailing edge stock
so it fits against rib #2 when placed against the aft
spar. When you have achieved the correct angle on
the end of the trailing edge stock, cut it where shown
on the plan. Glue it to the aft spar and #2 rib. The
approximately 18" of remaining trailing edge stock
will be the aileron.
Q Q 12. Do not glue the shear web between ribs
#2 and #3, but glue the rest of the shear webs
between the ribs with medium CA.
Q Q 13. Test fit the 1/8" x 3/8" x 24" balsa top
outer spar in the notches of the ribs. If necessary
adjust the notches and the tops of the shear webs so
the spar is fully seated into the ribs. Glue the spar in
place with medium or thick CA. Use the dihedral
gauge to hold rib #2 at the correct angle when you
are gluing it to the spar.
Q Q 14. Use medium CA to glue three 1/16"
die-cut balsa gussets to the ribs and aft spar where
shown on the plan.
O Q 16. From the 1/16" x 3" balsa sheet you used
for the shear webs, cut and test fit the sheeting for
the aileron pushrod guide tube exit that fits on top of
ribs #6 and #7. It is okay if the sheeting extends past
the ribs by approximately 3/32" or so. Glue the
sheet in position.
U U 17. Remove the T-pins from the wing panel.
Lift it off your building board and peel the wax
paper off the panel. Look for glue joints that don't
look strong and reinforce them with medium CA.
Pay special attention to the glue joints between the
shear webs and the spars.
