11.) Glue all (10) main false ribs in place.
12.) Glue the two W-1 center ribs in place.
13.) To fit rib W-3, you will have to trim the front and back tip to
match the leading edge and trailing edge curvature. Also you will
need to trim the spar notches so the spars will fit at the necessary
angle.
14.) Fit the false rib on the inside of W-3. Again trim the spar
notches so the spar will fit in place as was done in Step 13.
15.) Fit the false rib on the outside of W-3. Trim the spar notches
as done previously.
16.) Refer to Photo 10. Fit and glue in place the last two W-4 and
W-5 tip ribs and the two false ribs.
17.) Locate the four diecut leading edge pieces, two long and two
short. The angle is cut on the top of the LE to match the ribs. Cut
the angle on the outer end of one of the long LE strips and check
the fit with one of the diecut LE corner pieces. When it fits
properly, glue the LE to the ribs and laminate the LE corner pieces
right in place.
18.) Cut the angle on the end of one of the short wingtip leading
edge’s and fit to the laminated LE corner. Glue in place.
19.) Glue the aft (rear) 1/4” square spar in place.
20.) Cut the upper forward 1/4 x 3/8 x 24 spar to length. It ends
at the false rib about 2” shorter than the bottom spar. Carve and
sand the outer end of the spar from rib W-3 to the false rib and
glue in place.
