We've had a lot of rain, but fortunately minimal flooding. This means some time available in the shop. These ribs are all clamped in place, and since I took this picture a day ago, the ribs have been sanded so the chord lines align with the lower jig string. For some reason, the ribs as they were manufactured were such that they are canted upward when clamped in place. They all had to be trimmed slightly with the sanding wheel. It's nice to see these all in place. It no longer requires much imagination to see a wing shape here.
The flaps are controlled by a DC gearmotor which is attached to a torque tube that runs between the flaps. There are cutouts in the ribs to allow the tube to swing through. The torque tube pivots on hinges bolted into the rib at station #2. The tube is at a 5 degree angle to the ribs because of the wing dihedral. In this photo, one can see the flap end of the tube, the hinges, and the 5 degree wedges of spruce that are used to mount the hinges so that they do not bind.
The next task is to trial fit the aft wing spar.
