CONSTRUCTION OF 1/2 SCALE MODEL OF SHUTTLE CABIN

1. Tape, overlapping 1/2 inches, the 10 ft 9 in x 12 ft rectangles labeled (A) to make a 10 ft 9 in x 23 ft 11 in sheet,

24 ft (800 cm)

2. . Spread plastic sheet flat on the floor. Using a marker draw the triangles as indicated in diagram. Cut out the triangles. (total 12 triangle cutouts)

3. Overlapping edges slightly, tape AC to BC. Repeat until all 12 triangles have been cut out and taped.

4. Tape the two 10 ft 9 in edges together to make an open cylinder.

5. Cut a 4 x 12 sheet from your roll, then cut that sheet into 4 x 4 and 4 x 8 sheets. The 4 x 4 is (C) and the 4 x 8 is (B).

6. Make the nose cone from 4 x 4 feet square (C).

Locate the center of the sheet by folding in quarters. Tie a marker to a two foot long string. Holding the other end of the string at the center, draw a circle having a radius of two feet. Cut out the circle.

* *This will not be neat - - make it fit!

7. Cut-out 10 triangles, 2 inches at the base and 12 inches long. Tape together the triangle sides as you did the shuttle body. Tape nose cone to the small end of shuttle body.

8. Cut a 8 ft x 12 ft sheet the cut this into 4 ft x 8 ft (B) and 8 ft x 8 ft (0) sheets.

9. Make the final cabin wall from the 8 x 8 feet square (0). Use a piece of string (four feet long) and a marker to make a circle having a radius of 4 feet (same method you used for making the nose-cone

circle.) After cutting out the circle, tape it to the large open end of the shuttle.

10. In the large circle, cut a ~ 22 inch square (the size of your fan),just about 8 inches from the bottom. Insert in this hole a sleeve made by taping together the edges of plastic sheet (B). Sheet (B) is 96 inches x 48 inches. Tape AC to BO overlapping as needed to allow your fan to fit snugly in one end. **You may inflate now and mark the position for #11 or complete #11 before inflating.

11. Make the sleeve for the entrance as you did for the fan. Install this sleeve in the side of the shuttle.

or

Cut a hole twenty-four inches in diameter on the rear side for an entrance porthole. Cut a thirty inch square from "B". Tape the square on the inside of the orbiter just above the hole. Attach velcro strips to the sides and bottom of the square with matching velcro on the orbiter inside wall.

11. The fan may be placed in either sleeve if you elect to build an entrance sleeve.
