: Bill, you've hit the main design points. The joints are key.

: From a construction viewpoint, I'd build the frame in one piece
: with the sections meeting at double bulkheads, then go fetch a
: saw. When the longitudinal frame members are cut the strength
: and stiffness they originally possessed must pass through the
: bulkheads. The butt joints between them and the bulkheads must
: be stronger than the original members, also the bulkheads have
: to rigid enough to prevent any flexing between the sections. A
: geodesic pattern of struts (triangles, triangles) at the
: bulkheads adds rigidity for the least weight penalty.

Hi Terry,

I was planning on doing this at one point, plans changed and/or something else came up, forget which.

I'll be happy to watch someone else do this first :)
