Followed the instructions on David Richter's site, however building in this size, Stage II and III (and Stages V and VI) had to be done simultaneously. The size 2 struts will not bend enough to allow insertion without popping something else open, and with so many struts going into each connector, that can go downhill quickly. The solution is to create stars with at the end up to 8 struts in them, and put all 8 struts in (slowly) at once.
Building in size 3 would be much more forgiving, but I also like models that can fit through doorways...
