Sailplane Construction Project Session #47
Yesterday all of the top bulkhead pieces were
glued in place as shown below. Before I could add the stringers to top aft
fuselage and work out the fairing of the aft fuselage into the stab and fin,
I had to come up with an aft fuselage bulkhead in front of the stab that
extends out to the edge of the stringers also shown below.
Actually this is a double bulkhead made out two
pieces of 1/16" sheet balsa laminated cross grain together. Notice how the
outer bulkhead extends out to the edge of the stringers. To provide support
for the stringers, the inner bulkhead only extends out to the inner edge of
the stringers as shown below.
There is a void that had to be filled in from the
center side stringer up to the bottom of where the stab platform will be
that extends from the aft bulkhead back the end of the fuselage. This void
on the left side of the fuselage is shown below.
Soft sheet balsa was shaped and glued into this
long slender void area as shown below on the right side of the fuselage.
Notice in the picture below that these two added
pieces not only fills in the voids on the sides, but provides for a double
gluing surface foot print for the 1/8" stab platform sheets that will be
added forward, aft, and between the two plywood stab mounting
