1)Now I have it tied all up in the jig with clamps and all I am constantly checking the level to avoid twist
2) The aft view of the jig. there is a large aluminum 1/4 in angle on the top of the 2x4 used for the rear spar support to keep that support surface as straight as I can.
Note the rest of the aircraft in the backgound, pretty much ready to accept the wing rigging.
