Airborn 1600 build Wing midsection bisection and tip joining
Cut all the midsections into two pieces right down the center line, through the joiner tubes
and into two equal parts with tubes perfectly aligned and ready for plywood end cap ribs.
One picture shows the cut through section with a 1/16 Ply end cap rib not the joiner tubes
showing through. A carbide blade cuts these tubes very well.
Then we cut the dihedral angle on all the the midsection tip ends and the matching
angle on all the wing tips. Nothing like a radial arm saw to do this with a nice 80 tooth
carbide blade for a slick cut. Also I made a little jig to align the tips for a square cut.
Just basically a wedge of 3/4" wood cut at the complementary angle of the tips
leading edge angle and trailing edge angle.
With all the dihedral angles cut on all the pieces we primed all the raw ends of the
parts like spars, Trailing edges and leading edges with thin CA.
Then I used my wing dihedral joining jig to match all the midsection halves to their
respective tips. Easy to line each wing panel up and joined.
Next will be the dihedral braces and ribs at the joints, also epoxy on the end cap ribs.
