  We provide an example in each rank of an ageometric fully irreducible outer
automorphism whose ideal Whitehead graph has a cut vertex. Consequently, we
show that there exist examples in each rank of Handel-Mosher axis bundles that
are not just a single axis, as well as of "nongeneric" behavior in the sense of
the "train track directed" random walk of Kapovich-Pfaff. The tools developed
here also allow one to construct a whole new array of ideal Whitehead graphs
achieved by ageometric fully irreducible outer automorphisms in all ranks.
