18. OPTIONAL: Glue the green engine
block into the long sustainer tube, 1-1/4
inches (3.2cm) deep. To save weight, you
can leave out this piece.
19. Cut out the shock cord anchor from
the front of instruction sheet. Spread glue
on one side. Take the free end of the shock
cord and lay it diagonally across the paper.
Fold it twice on the marked lines, and then
curl it slightly so it will fit into the long tube
with the fins.
20. Glue the shock cord mount into the
front of the long tube with the fins on it.
Make sure it is deep enough to allow the
shoulder of the payload section to be in-
serted into the tube.
21. Thread the free end of the yellow
shock cord through the hole in the base of
the transition. Tie a loop in the front end.
This will give you a place to tie the altimeter
to the rocket in case the model separates
in flight. Tie a big enough knot about 1.5
inches (3.8 cm) from the tip of the loop in
the cord so it can't be pulled out through the
hole. Pull the cord so the knot is at the base
of the transition. Using thick CyA adhesive,
glue the knot inside the base of the plastic
transition.
22. Tie a loop knot into the shock cord
as close to the base of the transition as you
can. This will be the loop used to attach the
parachute.
23. Assemble the NAR Payload by gluing
a cardstock bulkhead disk flush with the end
of the brown tube using wood glue. Allow
the glue to dry. Fill the tube with fine sand
(not included) so the entire payload weighs
28.0 grams. Remember to include the mass
of the second bulkhead when weighing it.
Shake the tube to settle the sand. Then glue
the second disk on the open end and allow
it to dry.
