D 26. Glue the 1/16" x 1" x 1" plywood hatch tongue
(FUN1F12) to the front of the hatch (FUN1F10) so that
half of the tongue extends past the edge of the hatch.
D 27. Position the hatch on the fuselage and use a piece
of masking tape to hold it against the hatch front and act
like a hinge. Push a T-pin through the hatch approximately
3/8" from the edge of the fuselage and 1/16" in front of
F2B. Pick the hatch up slightly and look
pin stuck into the basswood hold down. It should enter the
basswood as close to the former as possible (within 1/32").
If it does not, adjust the position of the pin and try it again.
Do this on both sides of the hatch and then drill a 1/16" hole
where each pin is.
D 28. Remove the hatch and enlarge the holes in the
hatch only 3/32".
D 29. Use two #2 x 3/8" sheet metal screws (SCRW024)
and two #4 washers (WSHR005) to screw the hatch into
place. Sand the sides and back of the hatch flush with the
fuselage sides and the face of former F2B. Be careful not
to round off the back edge of the hatch because the wing
fairing will bull up against this surface.

WING ASSEMBLY

NOTE: The following instructions explain how to build
the wing on a flat surface using the built in "Jig Tabs",
directly on the plans.

BUILD THE WING PANELS

NOTE: It will be helpful to build the wing on a piece of
"Celotex" or other semi-soft (and flat) surface, into
which you may easily slick pins
see where the
wing parts while building,
from lumber companies and home centers.
D 1. Tape the plan to your flat work surface,
the wing drawing with waxed paper (so you won't glue the
wing
you may cut the left and right wing half drawings apart.
D 2. The shaped wing leading edges (LE) (FUN 1W07)
and trailing edges (TE) (FUN1W08) are fastened to-
gether by thin strips of balsa. Separate them by cutting
between the two pieces. Sand away the excess balsa that
remains along the edges after cutting them apart, using a
T-bar with 100-grit sandpaper.
D 3.
