Here are a few more pictures:
The nose with the parachute. And to my delight, the hatch opening mechanism actually works!



My friend Johan got himself a cheap Chinese laser cutter, and with some adjustments it can actually cut balsa. Here is a first attempt to laser cut the formers for the rocket.

Just a few more details, and then on to the catapult.

Hi Gunnar,
this is a wonderful replication/reconstruction. I do hope you will be able to make the high-powered catapult now that Andy has sent you an example of this frightening piece of equipment!:dry:
Stuart Lodge can help you to fly your model with, say, and Estes motor, but if you want to use an authentic Jetex 50HT motor you will need to know how the pellets are ignited to give the necessary thrust.



Details can be found in the archives, see:
archivesite.jetex.org/motors/motors-50r.html

You will see that ordinary pellets can be used if modified with grooves so that they are lit top, bottom and sides. It takes a lot of fuse.

Good luck.B)

Gunnar,
The pellets are cut using a tile saw...slowly.
