I used WOF plans, but made a cardboard mold and fiberglassed it. A Vasaline like release on the mold allowed for the card board to be torn away. Had to upscale to compensate for thickness of fiberglass and my arm size. Te fiberglass top and bottom halves needed Bondo to fill in bubbles, etc. The rocket is made of PVC pipe and connectors. The ribs are 1/8 PVC strips. The rocket tip was made using a small funnel as a mold to cast a basic fiberglass shape. Careful work on a belt sander to shape the back angle. I drilled a hole through the back of the tip that a nail goes through and a larger hole for a dowel that is glued in place, holding in the nail. The silver tip was made by dremmeling down a small piece of dowel. The sawed off nail tip ca be seen at the front of the rocket tip. I drilled holes in the copper colored part by putting a small drill bit in a dremmel.
