Reflective objects need an environment to reflect, whereas your lathe 
and the tiles it's sitting on appear to be floating in empty space. You 
might consider putting everything in a shop environment, or even an 
empty room (although the reflections from an empty room will be really 
bland.. still better than nothing though).

Using low-quality radiosity will then give the room a more realistic 
appearance, which will improve the reflections, as well as brightening 
up the inky black shadows on your lathe (eliminating any need for 
ambient finishes.. remove 'em!), and shouldn't make render times 
unacceptably long.

If for some reason you can't or won't do this, at least scatter around a 
couple more point lights.

I'm sure I could say more about the textures themselves, but I would 
prefer not to judge them in their present lighting environment.

Oh yeah, and don't scale anything by 0. That's just dumb. I'm actually 
surprised POV-Ray let you get away with it.
