First cut out the wing skin, with the flutes running up and down
(chordwise) as shown in the drawing:
Then cut out the
ailerons as pictured in the drawing:
Mark the hinge
line on one aileron. Lay the other aileron against it, as it will go
on the wing, and mark the other hinge. This will make sure you get the
flute cut on the right side.
Now, mark the
center of the wing. This is the center fold line. Mark a line 3/8"
on each side of the fold line. Score all 3 folds.
This
is how i hold the straightedge while i score my wings. I use a dremel
engraving tool to score with, it makes scoring very easy. A good #1
Phillips screwdriver works well, also. Make sure to get the scores nice
and straight.
