: Bill, for my own information, how strong and flexible does the
: frame-to-stringer joint have to be? Flexibility requirement
: probably depends on how heavy the frame is - a heavier frame
: would need to have more rigid joints to distribute stresses
: whereas a lighter frame would need the flexibility to absorb
: shocks.

: I imagine lashing is more than enough, and flexible too, but it
: sounds a bit fiddley and rough on (my arthritic) hands.

: Screws would be fast with immediate hold, but I can see then
: working loose with the flexing of such an open structure.

: As for nailing, all the hammering is going to disturb the previous
: joints IMHO.

: Joint area is not enough to do the job with glue: it would need
: around x10 area I suspect to prevent joint failure because the
: joint would not flex.

: Oh for a really long Pop rivet . . .

That's the advantage of thickened epoxy, with filets you can expand the glue area.
