4. Cut a shaped 18” [457mm] balsa
flap spar
to fit between flap ribs W2A and W8A. Test fit, then
glue the flap spar in the notches of the flap ribs.
❏ ❏
5. Starting with 80-grit sandpaper on a large
sanding block or your bar sander, sand the
remainder of the jig tabs from the ribs and blend the
bottoms of the aft spars, the aileron spar and the LE
to the contour of the ribs.
❏ ❏
6. Use a bar sander and 150-grit sandpaper to
bevel the trailing edge of the top wing skin so it will
accommodate the bottom skin. While you sand, apply
pressure only to the sheeting and use the ribs to set
your sander at the correct angle.
Do not
bevel the
trailing edge to a
sharp edge but leave about 1/32”
[0.8mm]
squared off.
Hint:
Support the TE with the
edge of your workbench or a platform while you sand.
❏ ❏
R12. Drill holes in the rails and mount your
landing gear. Use the screws included with your
landing gear. Remove the landing gear and
reinforce the holes with a few drops of thin CA.
When the CA has cured, reinstall the landing
gear.
Hint:
Countersink the holes in the landing
gear for #6 x 1/2” [12.7mm] flat head screws.
❏ ❏
R8. From a 1/4” x 3/8” x 24” [6.4 x 9.6 x
610mm] basswood stick, cut a piece that is 1-1/2”
[38mm] long. Glue this
landing gear rail brace
to rib doubler W5R and the bottom of the forward
landing gear rail with 30-minute epoxy.
❏ ❏
R9. Test fit your retract unit with only the strut
but not the wheel. If necessary, enlarge the
clearance holes in the ribs and doublers so the air
cylinder and the strut do not interfere with the ribs.
❏ ❏
R10. Cut along the line you started earlier
on rib W3 for the wheel cutout and remove the
section of balsa for the wheel.
❏ ❏
R11. Mount a wheel to your landing gear
strut. Cut the axle to length. Place your retract
unit on the landing gear rails in the location
shown on the plan (by the way, the oleo
scissors
face
forward
). Retract the wheel by hand to
check the operation and make sure your retract
is mounted in the correct location.
Now is the
time to plan your installation and make sure
everything fits. It will be more difficult to make
corrections after the bottom sheeting is in place.
❏ ❏
R7. Cut the 1/2” x 3/4” x 6-3/4” [12.7 x 19 x
172mm] grooved basswood
aft landing gear rail
to a length of 6-1/8” [155.6mm]. Test fit, then glue
the rail in position with 30-minute epoxy
(with the
groove facing the top sheeting)
. Test fit, then
glue the 1/4” x 1/2” x 9” [6.4 x 12.7 x 229mm]
plywood
forward landing gear rail
in position
with 30- minute epoxy. Immediately proceed to
the next step before the epoxy cures.
Perform steps R7-R13 if you are installing
retractable landing gear.
Note:
Details for retractable landing gear are
shown on the
right
wing plan. If you are going to
install gear doors on your T-34, you will need to
recess the retract units into the landing gear rails
so that the doors will be flush with the bottom of
the wing. If you do so, reinforce the top of the
forward 1/4” [6.4mm] ply rail with some leftover
1/4” x 3/8” [6.4 x 9.5mm] basswood.
