Having used cable ties to temporarily hold the rigging in place on the starboard rigging in position I have now replicated the work I did on the port wing and swaged and ferruled them properly.
Once these are done the wing pair become almost a single unit and (coupled with the jury strut) everything just tightens up nicely.
In the is new state I can consider properly folding the wings back in turn and checking the fit under the fuselage and also the alignment with the tailplane.
One other thing I can start to manufacture is a board clamps that we effectively clamp either side of each wing strut to provide additional security when towing on the trailer. (See picture below from the original TLAC board)
