Construction - Traditional Flyers

  1. Open all SPAM cans and place contents into Mom's Tupperware salad container. Remove can lids and bottoms and wash thoroughly to remove all grease and meat products

     
  2. Once dry stack the  Round Cans One on top of each other securing them to each other with 1" wide strips of DUCT TAPE.  Be sure to pull the tape tight to hold cans together well as flying can cause stress. (If you live where round cans are not available, either use the rectangular ones and modify the shape of the loaf - cone - or purchase a body tube to go with the plastic cone or loaf you bake and color it with #2 colored pencils or magic markers.
     
  3. Drill 2 holes in each square SPAM can and into the column of round cans as shown in drawing #1.  Secure construction with pop rivets.
     
  4. Duct Tape "fillets" can be added for esthetics.
     
  5. Mold the SPAM in the Tupperware salad container into the shape of a nosecone on an un-greased cookie sheet and bake at 350 degrees for about an hour or until golden brown.  Turn oven down to 120 degrees and dehydrate until completely hard.  As an alternate, use the LOC plastic nose cone and paint it to look like cooked SPAM.  If nose weight is needed, fill the plastic cone with SPAM but be sure to reinforce the shock cord attachment point as extra weight will break the plastic loop provided.
     
     
  6. Drill 2 small holes in the 3rd can from the top and thread through the SCM-2 shock cord mount making sure you have about 2" of mount inside the rocket to attach the shock cord to. Thread the ends back into the opposite holes they came through and tie together back inside the rocket. Epoxy a glob over the ends and secure with duct tape to smooth if necessary.
     
  7. Tie shock cord to SCM-2 using 2 square knots. Wrap knot with small strips of duct tape to smooth.
     
  8. Secure the other end of the shock cord to the nose cone. If the SPAM cone is used, drill into the center and epoxy cord directly into the core.  Do not attempt to fly this cone - it is strictly for looks.  Use the plastic cone.
     
  9. Epoxy the centering rings onto the motor mount tube about ¼" from each end.  Fillet when cured to reinforce.
     
  10. Sand motor mount assembly if needed to fit into round cans.
     
  11. Place a bead of epoxy about 7" into the rear of the rocket and slide in the top of the motor mount assembly.  BEFORE it dries place another bead of epoxy about ½" into the rear of the rocket and continue sliding the motor mount assembly into place.  Set aside to cure (harden).
     
  12. Site a line for the launch lug as shown in drawing #1 down the length of the body and epoxy on the launch lugs halves about 12" apart and in line.
     
  13. Apply additional fillets to the rear-centering ring and launch lugs.
     
  14. Attach parachute about 1 yard from the nosecone.
     
  15. Use masking tape to friction fit a motor of incredible power (E9-4) into the rocket and let her fly.
     

NEW AGE FLYERS INSTRUCTIONS

Put all of those expensive unnecessary items in a box and auction them on ROL for 30% more than you paid for them.  Follow the traditional flyers instructions and put the money you save into more rockets and motors.  Rockets shouldn't live forever -- at least that is what Dad says.
