3. Lightly sand the surface of the upper body tube around the
launch lug slot. Apply cement to the base of the remaining
launch lug. With the sloping portion of the launch lug toward
the front of the upper body tube, insert the tab on the bottom
of the lug into the pre-cut launch lug slot in the upper body
tube.

4. Apply cement to the base of a launch lug. With the sloping
portion of the launch lug toward the front of the lower body
tube, insert the tab on the bottom of the lug into the pre-
cut launch lug slot in the lower body tube.
5. Apply a base primer coat of paint to the lower body tube.
After the base coat has dried paint the entire body tube
insignia white. Allow to dry thoroughly. The back 3.52"
(89mm) of the body tube is painted matte black. Mask off
and paint this area accordingly.
5. Screw the other screw eye all the way into the hole in the
bulkhead (1/16"1.6mm thick). Apply a bead of cement
where the screw eye meets the bulkhead.
6. Pass the free end of the remaining shock cord through the
coupler tube (6"/15cm long) and securely tie it to the screw
eye attached to the bulkhead with a square knot. (CAU-
TION: Do not put cement on the knot of the shock cord.
Cement will weaken the shock cord.)
7. Cement the bulkhead plate to the end of the coupler tube.
8. Make a pencil mark 3" (76mm) from an end of the coupler
tube. Lightly sand the surface of the coupler tube between
the mark and the bulkhead. Use a small dowel to apply a
bead of cement around the inside of the upper body tube
about 1" (25mm) from the back end of the tube. Then slide
the coupler into the upper body tube up to the pencil mark
on the coupler tube.
