Daedalus Model Update
Terry Regan is building a detailed model of the Daedalus craft. Here is a brief update of his latest progress…
So far I have made the reaction chamber, the support structure and the induction loop.
I test fitted the induction loop to the reaction chamber, and at first I was happy with the way it was looking, but there was something that didn’t look quite right. It turned out that the distance between the loop and the chamber was too large, so I removed all the “V” shape brackets and made shorter new ones from .8mm brass rod, and soldered on the top locating pins so that it would make a good solid joint. I reassembled the loop to the chamber and: perfect! – it all looked right.
Next step was to make the parabolic reflector. This was made out of 1.5mm styrene card, and the centre was cut out for the pellet injection gun. I marked out where the four propellant tanks are to be fitted, drilled and added four rods for the tanks to be attached to. I moulded a funnel for the pellet injector gun by plunging a brass drawer knob into soften styrene card, and then glued this to the centre of the reflector.
The four fuel/propellant tanks are Christmas baubles, cleaned up and detailed. The support structure that fits around the payload bay was made from 1.2mm styrene rod, and I drilled down the centre with a .5mm drill and fitted 15 Amp fuse wire for the locating joints.
