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.

1-1/4" (3.2cm)

1.0" (2.5cm) minimum

Approx. 1.5" (3.8cm)
