  CXO imaging has shown that equatorial tori, often with polar jets, are very
common in young pulsar wind nebulae (PWNe). These structures are interesting
both for what they reveal about the relativistic wind itself and for the
(nearly) model-independent measurement of the neutron star spin orientation
they provide. The later is a particularly valuable probe of pulsar emission
models and of neutron star physics.We describe here a procedure for fitting
simple 3-D torus models to the X-ray data which provides robust estimates of
the geometric parameters. An application to 6 PWN tori gives orientations, PWN
shock scales and post-shock wind speeds along with statistical errors. We
illustrate the use of these data by commenting on the implications for kick
physics and for high energy beaming models.
