  Design Features 
      Large Altitude BearingLarge Altitude Bearing 
      Flex Board Azimuth Bearing 
      Pyramid Shaped Spider 
      Lightweight Open Architecture  
Simple concept-make a large Aperture Telescope as light and minimalist as possible, manageble by one person and able to travel in a small vehicle with room for camping provisions.  The total weight was 105 pounds, with the heaviest piece 72 pounds, that being the Cell/Mirror combination.  The Pyramid Spider replaced the Cage structure.  Aluminum straps and corner gussits added regidity.  The Cage nests on the "Mirror Box" for travel.   The material was Baltic Birch with an epoxy coating including the Mirror Cell.  Lots of holes to reduce weight, combined with aluminum gussits and straps to add rigidity.  The trusses are made from foam filled 3/4 inch Graphite tubing and the Spider is made from Aluminum and Composite plates.   A Flex Board Azimuth with Cam Follower Bearings for the large Alt Bearing sits on a heavy hub-less Ground (Board) Base.  The Base is "hub-less" to permit Mirror clearance as the Telescope rotates to the horizon.  The Azimuth surface needed frequent cleaning to maintain smooth motion.
