3. D SAND THE WING FAIRINGS TO SHAPE
Prepare to install the wing fairings by drawing lines
on the bottom of the wing even with the fuselage sides.
Cut the fairings to width. Sand to shape by placing sand-
paper on the wing and working the fairings back and forth.
*The 60 size has three fairing blocks where the 40 size
has only two. Sand the blocks to the shape of the wing and
also sand them to mate squarely with each other.
4. D GLUE THE FAIRINGS IN PLACE; SAND THEM TO
FUSELAGE CONTOUR
Drill holes through the fairings large enough for the
wing bolt heads to pass through. Install the wing bolts and
glue the fairings in place with 5 minute epoxy. Be careful
not to get any epoxy on the wing bolts and not to glue the
wing to the fuselage! When the glue is dry, sand the fair-
ings to the fuselage contour.

5. D USE DOWEL JIG AND DRILL HOLES IN THE WING
LEADING EDGE FOR DOWELS
(The dowel jig is used to help you drill holes in the
wing leading edge. The jig also gives you the location of
the 1/4" holes in bulkhead #2. You drill the wing holes first,
position the dowels and jig and then drill the holes in the
bulkhead after the wing is in position.) Use the plan
template and mark and drill 1/4" holes in the 1/8" Ply dowel
jig piece. Center the dowel jig over the wing leading edge
making sure the holes in the jig are centered on the wing
leading edge centerline. Drill 1/4" holes into the wing
leading edge and through both 1/8" dowel plates inside the
wing. Be sure that the holes are drilled parallel to the rib
centerlines and at 90 degrees to the wing leading edge.
6. D REALIGN THE WING TO THE FUSELAGE; GLUE
DOWEL JIG TO FUSELAGE
Place 1/4" dowels into the holes in the wing leading
edge. Place the dowel jig on the dowels. Position the
dowels so they are flush with the dowel jig when the jig is
next to the wing. You may want to tack glue the dowels to
the wing so they don't fall inside the wing during this step.
Now place the wing, dowels and dowel Jig into the wing
saddle. Realign the wing. Push the dowel jig forward
against bulkhead #2 and tack glue the dowel jig to the rear
of bulkhead #2. Remove the wing and dowels from the
fuselage.
