I've just been reading about a few others' observatory projects so thought I'd post a brief update on my efforts thus far: (my day job keeps getting in the way...)
- Pier and slab poured Aug 07 - 457 mm dia RC
- Geodesic dome constructed Jan 08 - 3.6 m dia. plywood
- Turntable constructed March 08 - 100 x 50 ply, with rolled 75 x 75 x 6 angle
- Building constructed June 08 - circular, stud frame, mini-orb cladding, with observing floor 2.2 m above slab.
- Dome lifted into place Aug 08
- Current works: weather sealing (it's been an excellent spring season here to thoroughly test it!)
- Still to do: stairs, power, lighting & comms, pier extension (steel pipe), fixed wedge
