  I had almost always used sor when making this type of object before (CSG
differencing for interiors) but not
many with clear textures.
  The typical view being from above, and creation testing being faster while
non-transparent, could cause a
person to not realize this problem.  I almost always instinctively add sturm anyhow
although reading
documentation again seems to make it useful only for the quadratic spline in lathe. 
cubic and bezier already
implement it by default.  sor however needs you to add sturm yourself even though it
is also cubic spline.

I'd like to see the source to at least the rainbow myself, but I'm confused as to
where that slightly yellow haze line in the horizon comes from?  Is that a side
effect the blackish line in the thermometer itself?

Uh-oh, didn't I ever say where I posted it?  Doesn't look like it.  Well it has been
at povray.text.scene-files
for a short while.
I think you're talking about the sky and it's gradient y backdrop for the color behind
the clouds.  When the
plane was clipped by a box it left that up in the air and I didn't think of it being
like that.
The wrong part of the lathe is just below the uppermost float, maybe I didn't point
that out before because the
plane used to align there also.  The line above that float is the liquid level.  Hope
that explains it now.
