Two days ago I was looking at a pile of bent, cracked and broken rockets, the sad legacy of experimental rocketry combined with plenty of builder/operator error. Determined to salvage something from this pile, I cut away some crumpled sections from a few tubes, salvaged a nosecone, and stood looking for quite some time at a fin unit sawn and pulled from a crumpled tube.
Salvaged fin unit from Estes Generic E2X, makings of motor mount.
Completed motor mount.
Motor mount mocked up in reversed fin unit. Note how, suddenly, the fins become tapered towards the trailing edge, and a plausible boat tail emerges.
