We use a pair of polarizing lenses on our microscope at work to identify birefringence in certain specimens (looking for uric acid crystals mostly) It is pretty neat, and very easy.)
I would think with a couple of cheap photography polarizes and a hole saw one could knock up a polarimeter in no time - though I understand that there are certeinly times where simply buying one fits the bill best.
