GLASSING THE AILERON SLOT FOAM CORE SLOTS
.....
The aileron slot foam core inside slots are glass ed with 2 BID
at 45 degrees to the spanwise direction. (i.e. T.E.). Knife trim to
the edge of the foam core, as shown on the sketch.
SHOULDER HARNESS INSTALLATION
.....
Remember those 20 BID plies that you laminated over the two
SH1's when you performed the "BOTTOM" skin and spar cap lamination?
Now is the time to drill and tap each SH1 with a 1 x 28 tap for a AN4
bolt later. The sketch shows the complete assembly. We don't
recommend actually attaching the shoulder harnesses until after the
main wing is mounted to the fuselage. Note that both shoulder harness
straps of each shoulder harness assembly are attached to one bolt, in
a Y fashion. Also, the 4130 Steel Bushing should be as short as
possible, to reduce bending loads on the bolt.
