9. Wet the outside of the sheeting where it curves around
the bottom of F1. Slowly bend the fuselage side along the
curve. If it begins to crack, moisten the area with more
alcohol. Once you get the wood to bend along the curve,
soak some thin CA into the joint between the right fuselage
side and F1. Continue to hold pressure on the joint, even
after the CA has hardened.
Note: Put some wax paper or plan protector between your
thumb and the fuselage side so you don’t glue yourself to
the model.
Caution: Do not squeeze the joint too tightly or you will
break the fuselage side.
❏
10. While still holding the joint tightly, fit and glue the strip
you prepared in step 8 to the back of F1, along the side of
the fuselage. It does not have to fit tightly. Soak some thin
CA onto the area, keeping the strip in place. After the thin
CA hardens, fill any gaps with medium CA. Do not release
pressure on the joint until after the medium CA has fully
hardened. CA accelerator will speed the process.
❏
11. In the same way, glue the left fuselage side to former
F1. Before doing so, glue the die-cut reference cut lines with
some thin CA. As you glue the side in place, it may crack at
the bottom of the cut line. Once the side is glued in place
any cracks can be sanded smooth and filled with lightweight
balsa filler.
❏
12. Carefully sand the fuselage sides even with the front
of former F1. Do not push the sandpaper back and forth
across the joint. Rather, push the sandpaper across the joint
towards the center of the former. Be careful not to snag the
opposite fuselage side.
❏
13. Cut six 2" [51mm] sticks from the 1/8" x 3/8" [3.2 x
9.6mm] balsa stick. Working one at a time, glue three sticks
to the inside of each fuse side to create a gluing surface for
the bottom sheeting.
