59. Hold the wing securely in position on the fuselage and drill 3/16" holes through the wing and into the wing bolt blocks in the
fuselage. The drill should be held so that it is angled 90° to the top of the wing surface.
Remove the wing from the model. Use a 1/4-20 tap to cut threads in the wing bolt blocks. After removing the tap, coat the
threads with thin C/A glue to harden the wood. When dry, run the tap back through the holes to clean out the threads.
60.
Glue the 1/32" plywood wing bolt plates to the top of the wing. They should be
centered on the 3/16" holes in the wing. Now use a 1/4" drill bit to open up the
3/16" holes in the wing and drill through the wing bolt plates. Use the nylon 1/4-20
x1-1/2" bolts to mount the wing back into position on the fuselage.
61.
Trim or sand the bevel on the front of the two ailerons. Mark guidelines on the top,
front, and bottom of the aileron. Now use your hobby knife to trim the corners
away down to the guide lines. Lightly sand as required to finish the bevel. Hold the
ailerons against the wing trailing edge and cut it to the proper length. There should
be a 1/16" gap at each end. Also mark the location of the hinges and the aileron
torque rod.
62.
Cut the slots for the hinges in the wing and ailerons. Drill a 3/32" hole in the
leading edge for the aileron torque rod. You will also need to cut a small pocket in
the leading edge from the torque rod hole to the inboard end to accept the torque
rod wire and allow the aileron to be flush against the trailing edge of the wing. Test
hinge the aileron to the wing and make sure that the ailerons move freely.
You will need to cut a small angled notch in the bottom of the wing immediately in
front and in back of the aileron torque rod to allow it to move forward and
backwards, where it exits the bottom of the wing.
63.
Sand the wing entirely smooth and set
aside for now.
64.
Glue the 3/32" balsa sheet to the top of
the fuselage between F-3 and F-15.
Note that the grain runs left and right.
Position the sheet so there is an equal
amount of overhang all around. After the
glue is dry, trim away the excess sheet
and sand it flush on all sides.
65.
Glue the 1" sq. x4-1/2" balsa block into
position on top of F-9 and against F-3.
When the glue is dry, trim and sand the
block to the shape shown here and on
the plan.
