I am attaching a Rocksim file of a rocket I am currently designing/construction. Pay no attention to the internals.
I am trying to construct a fiberglass shell that would be the rocket 'body tube'. I don't know exactly how to go about it. Here is the current scheme. As for dimensions, it is 48" tall, 7" at the widest and a 2" motor mount.
Make two cardboard centering rings for the 7" part. Then every 2" or so make another ring the diameter of the parabolic curve. Then take 1/16 x 1/4 or 1/2 balsa strips and run them perpendicular to the centering rings. This would make a 'form' for the fiberglass. (Kind of like the shapes you see in an old diridgible (blimp)) Then run gummed kraft paper lengthwise on the 1/16 x 1/2 strips. This would for a paper skin. Next you glass the entire thing with probably 9 oz glass and then some 2oz glass. You let it set up and then take the cardboard and the 1/16 balsa strips out. The paper will probably be stuck to the glass so good it ain't coming out. Do this for both sections and integrate the fins into the process so you have a one piece fin can and one piece payload.
Any suggestions ideas?
