Indeed, Weyl's solutions are precisely the static axisymmetric vacuum solutions in gtr, and they have a simple and beautiful relationship to the corresponding Newtonian solutions: each Weyl solution arises from a Newtonian static axisymmetric vacuum potential, and in the weak field limit, the Newtonian potential is recovered from the Weyl solution.
Also, you should realize that the Chazy-Curzon vacuum is a specific one parameter family of vacuum solutions (-not- spherically symmetric in the near field) to the EFE, whereas solutions to the Watt-Misner theory are solutions with prior geometry to a very different field equation.
Remember that one of the points of this thread was that the family of Weyl vacuums (which consists of all static axisymmetric vacuum solutions in gtr) have a very simple "far field" or "weak field" relationship to Newtonian gravitostatics, but the "strong fields" of these solutions can be radically different from Newtonian gravitostatics.

 Some Scientifically Inaccurate Claims Concerning Cosmology and Relativity   (Site not responding. Last check: 2007-10-14)
The most interesting ones are constructed in stages and give the exact solution of the two-body problem in gtr (with specified multipole moments for the two bodies); these procedures are unfortunately rather demanding and probably over the head of all but advanced students of gtr.
It is true that (by construction), their spacetime is static, but unfortunately, their "solution" contains two plates composed of material which grossly violate the energy conditions of gtr, the relativistic analogues of the requirement in Newtonian gravitostatics that the matter density be everywhere nonnegative.
Be this as it may, incorrect claims are often made that it is always possible to interpret any solution in gtr in terms of "funny fields" on Minkowski vacuum which mimic the effects of spacetime curvature.

 Time Machines
This issue is to be settled by proving theorems about the solutions to the equations that represent what are taken to be physical laws operating in the general relativistic setting—or at least this is so once the notion of a Thornian time machine has been explicated.
Non-temporal orientability is not really an obstacle since if a given general relativistic spacetime is not temporally orientable, a spacetime that is everywhere locally the same as the given spacetime and is itself temporally orientable can be obtained by passing to a covering spacetime.
How to justify the singling out of one of the two possible orientations as future pointing requires a solution to the problem of the direction of time, a problem which is still subject to lively debate (see Callender 2001).

The influence of symmetries on the invariant classification of a general type N vacuum spacetime is studied.
It is shown that the existence of two independent symmetries (Killing vector fields/homothetic vector fields) reduces the upper bound on the Karlhede algorithm for such solutions from five to three (derivatives), as long as the vector fields obey a geometrical condition obtained here.
