  Cylindrical braneworlds have been used in the literature as a convenient way
to resolve co-dimension-two branes. They are prevented from collapsing by a
massless worldvolume field with non-trivial winding, but here we discuss
another way of preventing collapse, which is to rotate the brane. We use a
simple microscopic field theory model of a domain wall with a condensate for
which rotation is a necessity, not just a nice added extra. This is due to a
splitting instability, whereby the effective potential trapping the condensate
is not strong enough to hold it on the defect in the presence of winding
without charge. We use analytic defect solutions in the field theory (kinky
vortons) to construct a thin-wall braneworld model by including gravitational
dynamics, and we allow for the rotation required by the microscopic theory. We
then discuss the impact rotation has on the bulk and brane geometry, thereby
providing an anchor for further cosmological investigations. Our setup
naturally leads to worldvolume fields living at slightly different radii, and
we speculate on the consequences of this in regard to the fermion
mass-hierarchy.
