Carl Goldberg's 1938 Comet Clipper
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.
