Preparing to celebrate, next summer, the 40th anniversary of Apollo 11’s flight, I’m (finally) building the Apogee Saturn V (that I bought almost 10 years ago!). I’ll maintain a builder’s log here.

With the laying of the gussets on the motor mount centering ring, construction begins. Most interesting was constructing two perpendicular diameters on each ring: I’m glad I could remember some of my basic geometry (constructing a perpendicular bisector), and figure out enough of the rest from basic principles to be able to do it accurately. (Important observation: a perpendicular bisector of any chord will be a diameter.)

Along the way, I might let myself get slightly distracted to build another quickie model, since LUNAR will be able to fly at NASA Ames for a launch in August!
