Ernie, what's the Delta stressed for? I perused your site, but didn't
see an illustration of the spar attach fittings. A half-inch pin
sounds right. But what kind of fitting does it go through, and how is
that fitting tied into the spar? That's the real question.


Normal category. 1950lbs gross.

I just put a couple pictures and and explanation at the bottom of the
'Frame' section of my website. Follow the link below.

Tell your lovely wife 'thank' for helping out. I'm afraid it's still
not entirely clear, but it looks like the whole structure hangs on
those two 1/4" fittings welded to the spar truss, inserted into the
vertical hinge tube, and held in place by the 1/2" pin? Make certain
those are solid welds, my friend!
