5th July 2016 - Left wing intersection fairing - day 5

For the last few days I've been building the intersection fairing for the left wing. As at today the structure is complete and the next jobs are to fill/finish the outside surface and install plate nuts to the fuselage side and screw-in inserts into the wing root. I'm using screw-in inserts to take a M3 screw. These only need a 5mm hole so will easily install into the 12.5mm wide root rib. These will be glued into place so there will be no impact on the rib's strength.
The intersection fairing is made from 0.032" aluminium sheet with fibreglass laid up round the curves. A slurry of resin and microballoons on top of the glass cloth was used to create the leading edge shape.
