  Seems like a precision problem. Scaling everything by about 10 solves
the problem.

  This is the core of the problem:

#declare Scale = 1;

#declare eye = <-0.3,0.5,-0.3>*Scale;
lathe
{ linear_spline 2
  <0,0> <.01,.004>*Scale
  pigment { rgb 1 }
}
camera { angle 1 location eye look_at 0 }
light_source { y*10,1 }


  If you set Scale to 10, everything seems to be ok.
