I think the spider is needed to center the metal ring, which does not fit the platter precisely; once this is done, you remove it.
Clearaudio now have an acrylic ring which you put round the edge of the platter, allowing you to slip the metal ring on precisely in place with no spider needed. Works like a charm.
