wing tip rib W-145

Preparing for wing tips, I'm locating the wing tip rib (W-145). In Ch. 11,
p.1 (Fig. 11.1.1) the manual says to put the tip rib "over the wing skins"
and, as shown in the figure, with the flanges positioned on the inward side.
When I tried to do that, in order to get the tip rib far enough forward to
be at the correct 1/2" forward of the rear end of the flaperon, I couldn't
get it to fit at all without a very ugly squishing (stressing) of the wing
skins.

However, if I put the W-145 inside the wing skins, with the flanges pointing
outward, everything works great -- including the flaperon hinge bolt access,
etc. IMHO, closure of the rear end of the wing tip will look better with the
flanges inside the wing tip. Pictures at http://n254mr.com/node/187 &

Is my orientation of the W-145 with flanges outward a bad idea for some
reason?

Is this yet another place where the manual is, uh, bogus? So it seems.
