The materials for one model, including one rocket motor and igniter, cost under 10 EUR each.Materials
(first picture, from top to bottom, left to right):
A piece of 2mm thick balsa, 100 mm by 500 mm
A thin walled cardboard tube 20mm in diameter and 235 mm in length.
This is half the length of standard BT-20 model rocket body tube. I used a body tube from Opitec’s “Rocket model II”
A standard 19mm model rocket motors should fit in it.
20 cm of a balsa “stringer” with a triangular section 2x45°-90°, 10mm wide or smaller
Available at modelling shop for building flying model airplanes
A piece of 5mm thick balsa or light plywood, about 100mm by 40 mm
A wooden egg 40 by 60 mm
In case you do not have access to sanding equipment, a wooden half ball 50mm diameter is a better alternative, as explained in step 6 on the bow section.
A (wooden) button about 30mm diameter
A half ball, about 10mm diameter, in plastic or wood.
I happened to have plastic ones, clear and with a mirror base, a feature I used in a simple “window effect”.
A printout of the pattern/skin attached in the next step
Half the length of a standard 19mm diameter model rocket motor casing (A, B, or C type), emptied.
A screw hook or eye, maximum 13mm wide.
A streamer or a small parachute.About 50cm of Kevlar string as “shock cord”.
I like to use the “QUEST-way” to attach the shock cord to the rocket by tying it to the motor hook. This works fast and reliable, which is particularly important in workshops. I do not use elastic bands with streamers and small chutes. Obviously you can do it the classic “ESTES-way”.
A motor hook for standard 70mm long model rocket motors.
A launch lug, about 9 cm long.
I use a piece cut from a tube sold to hold up air inflated balloons. Do check if your glue works on them, as the plastics used are sometimes hard to glue (PE-like).Tools, paint and adhesives
(second picture, from top to bottom, left to right):
Sanding paper, medium grit
Gouache paint (school paint). I mixed the colour from blue, yellow, red and white
Cutting surface (I worked on cardboard, for the workshop it was not possible to provide enough self-healing cutting mats)
A metal ruler
Spray adhesive (contact glue)
A (columnar) drill and a 2mm drill bit (not shown)
If you use the wooden egg, a belt sander comes in handy (not shown)
Something to protect your working surface from (spray) adhesive (like old newspapers, cardboard… , not shown)
For the workshop we also used non-stick baking paper to work on when using superglue (not shown)Launching equipment
(third picture, from top to bottom, left to right):
A launch pad (I used a tripod made from water pipes) with deflector plate
An ignition system
A model rocket motor: B6-2 (first flight) or C6-3 (I used German WECO motors)
An igniter (I used KLIMA igniters)
An igniter plug (an Estes one is shown)
A 3mm launch rod
