Fit the formed
Wing Tip
in place at the end of the forward
Spar
and the
Rib WR5
and if the fit is good,
or adjust if needed then glue the forward end of the
Wing Tip
to the end of the
Leading Edge
flush to
the bottom edge. Next glue the
Rib WR5,
the
Spar
end and the
Rear Spar
that was angle cut to fit
flush. Allow the glue to set and now with the
Wing
on the
Building Pattern
for reference cut and fit the
rear end of the
Wing Tip
to the
Trailing Edge
. With a sharp blade taper cut the
Rear Spar
to blend
from
Rib WR5
to the
Wing Tip
then sand to blend and smooth the
Ribs
to the
Trailing Edge.
Add the twelve (12)
Leading Edge Stiffeners
centered between the wing
Ribs
with the back edge of
the
Rib Caps
aligned with the back edge of the
Forward Spar
as seen in the pictures on the next
page. Cut the front extensions off flush with the front edge of the
Leading Edge
. Cut an angled
chamfer on each of the
Stiffeners
front edge. (On the underside of the wing add
Rib Cap
extensions
from the edge to the
Ribs
to the front edge of the
Leading Edge
and cut flush.
This is only if
necessary if extensions were cut inadvertently
). Once the glue has set sand the
Cap
joints smooth
to each other, then starting with the lower edge of the
Leading Edge
sand using a flat sanding board a
small radius the length of the
Leading Edge
blending to the
Wing Tip
. On the top of the
Leading Edge
sand a much larger radius blending the
Rib Caps
into the rounded
Leading Edge
.
NOTE: Take care
not to sand through the Rib Caps.
Now do a final smooth sanding of the entire top surface of the
Wing
. Sanding diagonally across the ribs will provide a better result of wing curvature.
