wing fitting attach locating assemblies

I decided that I needed to build fixtures to mount the wing attach fittings to the fuselage.
As my basic welded fuselage is currently being fabricated in Toowoomba, Australia, this presented some issues with matching wings to fuselage.
(a small distance issue)....
The best way I could think of to accomplish this was to build dummy wing sections of the upper and lower wings, and mount the actual fittings in place. This then ensures that the wings will bolt to the fuselage exactly. (fingers crossed)
I built the lower wing fixture to be stub sections of both the Left hand and Right hand wings. The tube in the leading edge was for alignment only, but the tube behind the rear spar locates the aileron spar, and diameter to ensure there will be no longeron to aileron interference issues. I removed the fittings from the LH and RH wing spars and used them on the fixture, so all should line up on assembly.
Should being the operative word.
The top wing only required a spar assembly which locates the center attach fitting, and the rib profiles each side to set the incidence.
I plan that a side benefit of these two jigs will be to use them to fabricate the wing to fuselage fairings, as it is much easier to fit fairings on a stub wing assembly than to have the actual wings in place.
I boxed up these two jigs and shipped them off to Australia, where they are now on hand for fitting fitment.
