Estes Quinstar #7241 Build, Part 5, Dry Fit Cage

Look close at the picture to the right.
Where the outside ends cross, the holes on the outside (left of center here) should be smaller.
If you have two outside holes the same size, it is assembled incorrectly.

Try a dry fit first, no glue should be used until you are sure of the assembly.
Pieces 1 and 2 are slid together.
Enlarge the picture and you can see the numbers 1 and 2 are inside and facing each other.

Part number 3 is added.
The numbers 1, 2 and 3 are facing the inside of the structure.

Part 4 is slid in.

Part 5 finishes out the cage and forms a star and pentagon at the center.
Check the outside cross intersections. The right side will be higher than the left so the flat "K" pieces will end up at an angle.
