A few more pics to provide the illusion of progress on this project:
Above: ghetto frame mostly completed. In this pic it's
very firmly strapped to the car. Five... count 'em! 5 ratchet straps, 2 bungee cords (to be replaced by straps). Still some triangulation to be done.
I've extended a very light 1x1 frame out from the main frame to act as a skeleton. This one won't be a stressed skin structure like the Firefly tail.
Woo.
Starting on the "hip bustles".
