❏❏17. Carefully break away the short piece of flap
leading edge that was tack glued to the flap. Glue the
flap horn into the flap, then glue the flap leading edge
back on. Use thick CA or aliphatic resin so you will
have time to accurately reposition the leading edge.
18. Return to step 1 and build the right flap the
same way. Use the small hash marks on the right
wing plan to mark the flap hinge locations.
HINGE THE FLAPS
1. Glue together the die-cut 1/8" [3.2mm] plywood
pieces that make up the wing and flap hinge drill guides.
2. Optional: The drill guides may be used
as is
to
guide a 3/16" [4.8mm] drill while drilling the holes for
the flap hinges. However, for ultimate precision, 7/32"
[5.6mm] brass tubes could be glued between the
grooves of the guides to support your drill even
better. The grooves in the drill guides will have to be
beveled slightly to accommodate the tubes. (The
tubes can be seen in following photos).
3. Cut the hole in the flap bay trailing edge to
accommodate the flap horn. Position the flap on the
wing and use masking tape to temporarily hold it in
position. Referring to the wing plan, use a
straightedge and a ballpoint pen to lightly mark the
hinge locations on the flap and wing.
4. Remove the flap from the wing. Using the
appropriate drill guide, drill 3/16" [4.8mm] holes 5/8"
[16mm] deep into the flap. Hint: “Cleaner” holes can
be drilled with a 3/16" [4.8mm] brass tube sharpened
on the end. Note the marks on the brass tube
indicating the depth of the hole.
5. Drill the hinge holes in the wing the same way.
Stop drilling after you feel the drill (or tube) go
through the hinge block so you don’t go through the
top wing sheeting.
