Ground breaking for the observatory took place today. I have decided upon a more traditional slid off roof design. I will be making it out of an old trailer top my father used for stage shows to be held outside (held the weight of three 100kg plus men and a lighting rack with spotlights so i think structurally it is sound) will install 4foot walls around the base and simply have the trailer roof roll off. The beauty of this design is the roof was designed to be a mobile sound and lighting desk (light on top mixing desk with attendants underneath) so it is already kitted out with electrical. the pier will be a piece of 300 by 300 by 6mm steel (think industrial framework) about 2.7m tall (will be cut to size with about 70-90cm to be buried in the concert base.
photos to follow tomorrow
