Scratch-Built Model Rocket
Part 1: Intro and Overview
|Now the rocket has a name!
Ken, of Delanco NJ made several of these rockets using colored posterboard for the body tubes. His kids chose the colors, and his daughter Kristen gave them a clever and charming name.
So with her kind permission, I hereby christen this rocket model the
Made from posterboard and spray glue, they are quick, cheap, easy, and sturdy. Can be made lighter, at the expense of some sturdiness, or heavier, for greater strength.
This technique is adaptable to many other rocketry uses, such as inhibitor tubes, case liners, and small motor casings.
Sure, it's nice to have a wood lathe. But you don't really need one to get started. These cones can be "turned" with agile fingers from a 3x5 card, and are reinforced with epoxy. For what they lack in aerodynamics, they make up in simplicity and strength.
I use a simple, functional design, subject to aesthetic and perhaps aerodynamic improvement. Includes making and installing the launch lugs.
An easy way to create a fancy "paint job" for your rocket.
Thrust ring, shock cord mount, recovery streamer, motor retention, and launch video.

Photos of the October class launch, where this model was tested a number of times.
Everyone in the class assembled at least one rocket, some made more than one. On launch day, they were flown using Estes motors.
Except for some ejection failures, they all performed well and proved sturdy enough to survive a "lawn dart" recovery to fly again. I believe that my new motor retention system will solve the ejection problem, we shall see....
Here's one by Geoffrey Andrews which he has named Moonstone. I like that name - it matches the colors well. The tube is carbon fiber, both lighter and stronger than the paper tubes I am using. This one should really fly. Thanks Geoffrey!
