Why aren't the hour lines evenly spaced on a sundial? Of course the intent here is for a horizontal (or vertical) dial, but the asker of this question would probably not know that term. I've thought of another tip for spotting worthless horizontal sundials (such as is sold in garden shops, etc)--if the shadow of the gnomon crosses the hour lines it's no good. This test requires only horizontal positioning, not polar alignment, and a lot will fail this test because the gnomon for cheap dials often does not intersect the dial plate at the convergence point for the hour lines.
