L2 Rocket – Looking at components

I have finally purchased and received my L2 rocket parts; a kit called Katana 4 from AusRocketry. It is a fibreglass kit, 4″ suitable for J, K and possibly L motors. I’m going to take my time making this one, making sure I get all the joins really well done, the holes in the right place, the paint just perfect!

The first step has been to identify all the pieces.

Main components of Katana 4 laid out. Measurements included.

Well, not quite all the pieces, but some of the main ones. I will get myself a weigher (previous one stopped working) so I can get the individual weights. Then i’ll be able to create myself a simulation file in OpenRocket and work out how it will perform.

The second step has been to clean them up, vaccuming off dust and wiping any residual dirt. . See some pictures below.

Cleanliness is very important. We want to reduce chance of dust getting in the places we don't want it, e.g. Gluing, painting

Here are some other pictures to put the rocket into perspective.

The rocket stands approximately 2.4 metres and has a diameter of just over 100mm.
