Gluing
complete
on the inner wing section. Slip the lower main and rear spars in
at this point and hot glue them to the spar fence, but do not glue
them in to the ribs yet.
Setting
the
length of the lower main spar. Place the 1/4" balsa outer main
spar up against rib #10 and mark the spar at the location of the step on
the bottom of the balsa spar.
Next
mark
the top spar where the angle changes on the top of the balsa spar, and
cut the spars at the marks. I cut them a shade long and sanded
them while trail fitting the balsa spar in place against the #10 rib.
Use
the same procedure on the rear spars.
The
outer spars are in place but not glued.
The
#11 rib is put in place to test the fit, not glued..
With
the
two outer main spars removed from the inner wing section, the remaining
ribs are slid on in approximate position. As with the inner wing
section, this will be easier
with some prefitting of the ribs to make for just a slight looseness in
the fits. If any of the feet become separated at this step,
reattach them with a balsa
strip 1/4" wide with the grain vertical, tack glued to the rib and base.
See the inset picture lower right.
