Figure 155 slide the wing frame into the covering.
m) Collapse the wing frame using a scissor type motion so that it will slip easily
into the fabric envelope of the wing, Figure 155.
The trailing edge has the most fittings on it, so scissor the wing to insert
the trailing edge first.
n) Slide the frame of the wing into the cloth taking care not to damage the fabric
with any of the fittings attached to the frame.
Keep track of the turnbuckle, tie a bit of string to it if necessary.
o) Use the same type of scissor motion to expand the frame back to its original
shape.
Make sure that the fittings for ailerons, and flaps, as well as the strut
attachments, exit through their respective holes in the fabric.
p) Stand the wing up with the trailing edge on the clean surface, and the leading
edge up.
q) Attach a small rope through the grommet on the leading edge so that you can
use a bar to press against the leading edge of the frame to stretch the fabric
into place, Figure 156.
You may need to use a bar and pry against the leading edge tube,
being careful not to damage it. Note the piece of wood to protect the
tube end in the photograph.
Check that the fabric is properly seated at the tips of the leading and
trailing edges. It should be nice and snug, with no wrinkles near the tip.
If prop tape or similar has been incorrectly used it is possible that it will
grip the fabric and prevent it sliding down the leading edge, causing
difficulties later.
