CAP Payload Bay "EggLifter"
The CAP Egg Lifter was designed to further enhance the Civil
Air Patrol Model Rocketry Program as described in the training manual
50-20) by providing an inexpensive, easy to assemble payload bay that
is large enough to contain a raw egg.

pattern printed on white heavy index card stock
Elmer's type glue and/or Stick Glue
10-12 inches of flat 1/8 inch elastic
ruler or straight edge
Styrofoam egg carton
Assemble the forward and aft sections of the payload bay, then fit the
connecting ring around the middle of both and glue to the connecting ring
to the forward section of the payload bay.
Spray on several coats of "clear coat" to strengthen the outer
shell of the bay and use shock absorbent material to cushion the egg.
(I have used Styrofoam egg cups cut from egg cartons glued into the bay.)
Two launch lugs will be needed. Put one on the payload bay and attach
the other along the gray stripe on one of the fins of the rocket booster.
Insert a launch rod to ensure alignment of the lugs as you glue them into
