3. After the top of the leading edge is clecoed, flip the wing
over.
4. Using ratchet straps and a padded piece of wood to dis-
tribute the pressure, pull the leading edge skin back until
you can cleco its aft edge to the matching holes in the aft
skin and main spar.
Important: To keep the ratchet straps from deforming the
rear spar you must place a board in the channel of the rear
spar so the straps tighten against the board and not the
spar/trailing edge.
Important: Cleco the leading edge to the main spar be-
ginning in the center of the spar and working toward each
end.
Fitting the Leading Edge Skin
1. Cleco the top of the leading edge to the main spar.
2. Working toward the leading edge, center the ribs under
the pilot holes and pilot drill (#40 drill) and cleco the
leading edge skin to the forward ribs.
With the lower surface if the leading edge hanging free, drill
and cleco the upper surface of the leading edge working from
the spar forward.
Ratchet straps and a padded 1 x 2 work well to pull the lead-
ing edge down, and into position at the forward spar.
5. Working forward from the spar to the leading edge, center
the ribs under the pilot holes and pilot drill (#40) and
cleco the leading edge skin to the forward ribs.
