Once the glue has fully dried from the
previous stage, unpin the wing and flip over
again. Carefully trim the tabs off the top of
the ribs. You should notice now stiff and
strong the structure has become.
Because WS1 & 2 attach
to the plywood central
ribs, they need to be taped
down while the glue dries.
Use a sanding block
to make sure the wing
skins and false LE are flat
before glueing the LE part
into place.
Once the glue has fully dried from the
previous stage, carefully carve and sand the
leading edge until it matches the curvature of
the wing tips.
Use a sanding block to smooth
out all the glue joints between
the various sections of
sheeting.
