How to build a rocket
This guide is designed to explain the basic construction techniques involved in building a model rocket. I have no doubt that there are certain points that this guide will not cover in enough detail, so if there are any problems, please E-mail us.
Materials
The following materials are very useful in the construction of model rockets. Most are cheap, or even free, and they should be easy to get hold of. For specialist materials such as balsa or rocket engines, Howes Models on Broad Street, opposite Balliol, is a good place to look. Materials marked with a * are optional.
Cardboard tubes - from wrapping paper, or use a rolled up piece of card.
Cardboard - used to make fins and nosecone
* Balsa - used to make fins and nosecone
* Plastic nose cone - difficult to get hold of individually
Drinking straws - make excellent launch lugs
Plastic bag - to make a parachute
Elastic - for shock cord
Recovery wadding - Estes pack, or use baby wipes
Reel of cotton - used to attach parachute
Engines - Estes from Howes Models
PVA glue and Sellotape
* Sandpaper - to shape balsa fins
Pencil
Ruler
Scissors and craft knife
Swing testing
To make sure a new rocket is stable before its first flight, all new rockets must undergo a swing test. Attach a length of string around the rocket at its centre on gravity (i.e. its balance point) and swing the rocket around your head. Don't try this indoors. If the rocket is stable it should point in the direction in which it is travelling. If it doesn't, don't panic. Add extra weight to the nose, in the from of Blu Tak or small stones and try the test again. Finally, even if you don't manage to produce a rocket, come along to the society's Rocket Launch (See the termcard).
