The top wing was put on already and
attached to the Cabane Strut which is the center strut located just in
front of the pilot. The " I " Struts, landing wires and flying
wires are
also put on prior to this leveling procedure but left in a loose condition.
When the aircraft was designed the upper longerons were made to be completely
level with the direction of flight. Now that it's time to get the
wings aligned, this upper longeron becomes the main reference to ensure
the fuselage is level. Roger uses a bubble level on this longeron
to check this level. Now you can see why we used the milk crate as
a step. I'm not really happy with this method of leveling the
fuselage as you will see why in a later step. however, because of
the small spaces in the cockpit, I really don't know how else to complete
this step.
To get the planes fuselage level, shims
were placed under the tail wheel until the fuselage was completely level.
