Per the drawing, a 1/2 block is inserted under the rear spar, which would put a twist resulting in a lower angle of incidence at the tip (washout) which is the way it should be.........right? The trouble is, a page or two later, it says we're building the wing upside down, and reference the above drawing. If that's the case, and the above drawing is showing the wing upside down, then the incidence at the tip would be greater instead of less then the root..............or am I missing something here...........been working all day, so maybe I'm not catching something that is obvious........been there, done that before.
Thanks

PS, I'm having to build the wing, right side up, due to the top stringer being in the way to lay the outboard spars level on the saw horse.
