Insert the wings carefully, bit by bit into the wing
shapers until they protrude about 2 cm.
Optional Step:
You can now insert the wings (with the shapers
still on) into hot water to form the Depron to the
shape of the curves.
Briefly sand the inner parts which will be joined
at about 10 degrees before gluing them so they
fit together flush.
Glue the wings with the shapers in place and
allow the glue to dry before removing the
shapers.
The completed wing should have dihedral and
curvature.
