7.
Bring the ribs up to contact the straight edges. Place the outer rib to the
outside of the standoff tube. Drill outer ribs # 30 using the standoff tubes
as a guide and cleco. Drill outer ribs # 30 at the aft end through the
fuselage tabs (rib mounts to the outside of tab). Cut outer ribs off just aft of
the aft attach tab.
8.
Drill the center tab located at the leading edge spar carry-thru at its center
to #30 and countersink. The center support rib mounts to the underside of
the tab.
9.
Transfer drill center rib # 30 through the tab and cleco in place. Bring the
rib up to contact the straight edges. Place the rib to the left side of the
standoff tube. Drill #30 using the standoff tube as a guide and cleco. Mark
the aft end, so that it will slip on the stub welded at the top of station 3.
Check, mark and cut off. Slide the aft end on the stub and drill a #30 hole
from the bottom through the rib and into the stub. Reference also
FIGURE
06-04
.
10.
NOTE: It is possible that the standoff tubes extend past the top of the
support ribs and must be cut off.
See
FIGURE 06-04
. Leave ribs clecoed
in place for now.
11.
Burn small holes through the fabric at the locations of the 4 tabs on the aft
top of station 3. The skylight will later be riveted to these tabs.
12.
Lay the acrylic windshield in place on the aircraft. Establish the trim lines
where the windshield meets the boot cowl. A Dremel tool with a fiber-
reinforced cut-off wheel works well. Sand the edges smooth with a
sanding block. Start with 120 grit and work progressively to a finer grit.
13.
Pull each side of the windshield down tight against the boot cowling and
fuselage side tubes and clamp or tape in position. See
FIGURE 06-06
. It
may be necessary to trim the forward edge of the windshield to achieve
the proper fit inside the top joggle of the boot cowl.
14.
Find the center of the boot cowl and mark. With the windshield tight in the
joggle of the boot cowl, position the front trim strip so that the aft edge of
the hold down strip is flush with the instrument panel. The strip should lay
flat against the windshield and the boot cowl with no puckers.
The hold
down strip is retained to the boot cowl only. Do
NOT
locate rivets into
windshield. Position the center hole in the hold down strip on the
centerline of the boot cowl and transfer drill through the strip into the boot
cowl and cleco in place. Pull the hold down strip tight to the windshield
and boot cowl. Transfer drill #30 through the holes in the strip. Drill from
the center out alternating from side to side. Cleco as you go. Push the
sides of the trim strip and the windshield down and transfer drill from the
inside of the fuselage through the 4 tabs at each side, the boot cowl and
the trim strip. Cleco as you go from the fuselage outside.
NOTE: The
windshield sides are sandwiched between “Z” strips and trim strips. Do
NOT drill or rivet into the fuselage structure or windshield.
