Total build time: 242 hours.
The airfoil shape of the wings are formed and held in place by the wing ribs. There are 2 shapes of wing ribs, those that hold the shape of the wing in front of the wing spar (along the leading edge):
and those ribs aft of the wing spar along the middle of the wing (pictured below):
The trailing edge of the wing on the Waiex is shaped by the triangular control surfaces (flaps and ailerons) which I haven’t built yet.
For reference, here the picture again of the the small project part that I made while at the Sonex Workshop in October 2013:

There are 3 major parts in this simulated cutout of the leading edge of the wing: 1) the skin, 2) the wing spar (the flat part on the right, consisting of the spar “web” and top and bottom angle “caps”), and 3) the wing rib on the inside that holds the shape and strengthens the structure.
About half of the wing ribs get some additional strengthening near the root of the wing, partially because some of the rib must be cut out to provide clearance for the wing spar. This strengthening is done with gussets, which I bent (using a vice and hand seamer), drilled, and riveted into position. The gussets are specific to top and bottom on each rib, as the shapes are not symmetrical.
Each new rib, previously identical, is now specific to a particular place on the wing, since each rib has a specific clearance amount cut into it for the spar. There are 2 more specific wing ribs I have yet to build from blanks; the root ribs at the most inboard position on each wing, and the ribs that hold the aileron bell-cranks.
