4. Mark the Body Tube about 2.5 inches from Fin end of the Body Tube for the Launch Lug.

5. Mark the Body Tube 1 inch and 1.5 inches at the other end for the Shock Cord.

6. Make two ¼ inch long slits for the Shock Cord.



7. Push in the Body Tube at the slits with a toothpick.

8. Tie a knot in one end of the Shock Cord.

9. Push the knotted end of the Shock Cord through the bottom slit in the Body Tube.



10. Push the loose end of the Shock Cord through the other slit. Put glue on the Body Tube under the Shock Cord.

11. Pull the Shock Cord down flat. Make sure there are no twists in the part of the Shock Cord against the Body Tube. 12. Put glue along the Shock Cord where is meets the Body Tube. 13. Gently push the inside of the Body Tube into its original shape to help trap the Shock Cord.

14. Tie the loose end of the Shock Cord to the Nose Cone. Tuck the loose end of the Shock Cord into the Nose Cone and put a drop of glue on the knot.



15. Tie a loop knot in the middle of the shock cord to attach the parachute.

16. Glue the Launch Lug to the Body Tube, 2 inches from the Fin end. Make sure it is aligned perfectly straight with the long axis of the Body Tube. Do not get any glue inside the Launch Lug 17. Lightly sand the edges of the Fins to make them smooth and all the same size. Make sure the root edge (the edge against the Body Tube) of each fin is perfectly flat.

18. Glue the Fins to the Body Tube. A little glue, spread thinly, is better for this step. Make sure the grain of the wood in going at right angles to the Body Tube.



19. Use the Body Tube Marking Guide to ensure the Fin comes straight out from the Body Tube. Make sure the Fin is straight on the line. 20. Once the glue is dry make a fillet of glue along each Fin and Body Tube joint and the Launch Lug. 21. Assemble the Parachute according to the instructions in the Parachute Kit. 22. Attach the Parachute to the knot in the middle of the Shock Cord. 23. If you don't paint the rocket, you should at least spray a light coat of clear sealer to protect the rocket from moisture.

Recommended Motors: Estes C11, D12 and E9 motors Flight preparation: If the motor does not have a built in thrust ring, tightly wrap three layers of masking tape 1/2” inch from the nozzle end of the motors to form a thrust ring.

●

Trim the excess tape.

●

Insert the motor into the Body Tube. If the motor is loose, wrap enough masking tape around it until it fits snugly. This is called a “Friction Fit”. Put at least 4 sheets of wadding into the body tube above the motor. Fold the Parachute and insert it loosely into the body tube. It should slide easily. Put the excess Shock Cord into the body tube being careful not to tangle it. Slide the Nose Cone into the Body Tube. Make sure it is tight enough to stay on the rocket during the ascent but not too tight that it would keep the Parachute from coming out. Launch from a 3/16” rod that is at least 36” long.
