17. You are now going to sheet the top turtle deck back
from F-6 to the rear of the fuselage with the 1/8" x 3"
x 30" balsa sheet provided. We suggest that you
break this up into four areas; a left and a right from
F-6 to F-9 and a left and a right from F-9 to the back of
the fuselage. We also suggest starting at the center
of the top longeron and working down. Wetting the
wood with either water or a little ammonia will make
the curves required quite easy. Also be sure to leave
yourself a little "shelf" at the F-6 former for the for-
ward sheeting and at the F-9 former for the rear
sheeting. Take your time, trim and sand the sheeting
for a good fit before glueing in place. A thick type CA
glue is good here as it eliminates the need for pins.
18. Cut, fit and glue in place the two side cow/longerons
which fit into the half-notches left in the F-4's and ex-
tend out to the F-2 location. (See illustrations and
Top and Side view of the plans.) Locate and remove
formers F-1 and F-2 from their die-cut sheet. Observe
how F-2 sits in place when attached to the three 1/4"
sq. pieces extending out from the cowl. Viewed from
the side and top, F-2 is parallel with the firewall. Use
a ruler to be sure and trim the ends of the 1/4" sq.
material as needed. Once satisfied, glue F-2 in
place. Use your sanding block to lightly sand the for-
ward face of F-2 smooth. Position F-1 in place
against F-2. Note that doing this creates an approx-
imate "shelf" of 1/8". This is to locate and glue the for-
ward cowl sheeting in place. Glue F-1 to F-2. Last,
glue the two required 1/4" sq. balsa pieces that fit
from the bottom, outside corners of F-2 down to the
bottom, outside corners of the F-4's. Bevel-cut each
end of these to fit correctly.
19. Note the illustration in the lower left-hand corner of
Plan Sheet 1. This gives the correct sequence for
finish-sheeting the fuselage top and cowl. Again,
wetting the various balsa sheeting pieces with water
or a little ammonia helps the material to readily con-
form. Take your time to achieve accurate, gap-free
fits before glueing these pieces in place. Thick CA
