Apogee Aspire Rocket Assembly

1. Fine sand the balsa die-cut sheets before

removing the fins. Carefully remove all the

pieces from the balsa sheet by freeing the edges

with a sharp hobby knife.

2. Group the four fins together, and gently

sand the edges as shown in the illustration.

3. Test fit the red coupler in place into one

of the body tube sections (If you have trouble

inserting it, try sanding the coupler or peeling off

some of the red paper layer). Apply wood glue

around the perimeter to one end of the red tube

coupler. Quickly insert it 1/2 way into one end of

a 29mm diameter body tube. After the glue has

set, apply glue around the portion sticking out,

and insert into the other 29mm body tube.

Note: If you plan on using longer 29mm rocket

motors than the 3.5" (8.9 cm) long Apogee F10

composite propellant motor, you may omit the

next step.

4. Carefully glue one of the CR24-29 center-

ing rings into one end of the body tube assembly

using wood glue. Recess it 3-1/8 inch (7.9 cm)

into the tube from the end. It is easiest to push it

into the tube using a 29mm diameter rocket mo-

tor. From now on, this end of the tube will be the

aft end of the tube.

5. Cut out the tube marking guide from the

pattern sheet. Wrap the guide around the aft end

of the body tube and tape the ends together.

Mark the body tube at each of the arrow points.

Remove the marking guide.

6. Using a door frame, draw a pencil line

down the outside of the body tube at each pencil

mark. Label the launch lug line so you don't glue

a fin in the wrong position.

7. Apply glue to the root edge of one of

the fins. Allow the glue to dry slightly for a few

minutes, then attach it to one of the body tubes,

as shown in the illustration. Each fin is attached

.75" (19mm) from the end of the tube. Make sure

the fin is straight along the tube. Allow the fin to

dry before proceeding with the next fin. Repeat

this step three more times as you attach the

other two fins.

8. Apply a bead of wood glue to both sides of

each fin-body tube joint. Pull your finger along

the joint to smooth out and remove the excess

glue. Lay the tubes horizontally while the glue

dries. (Note: If you plan on flying with high thrust

rocket motors to achieve supersonic speeds, it

is recommended that you apply a fillet of FIXIT

Epoxy-clay

to each of the fins to add extra strength.
