GerKonig - I have a third way of locating a lost part - Ask my wife to use a vacuum cleaner with an almost full dust bag to clean the area . In less than 30 sec I will hear the part rattling up the hose. Then its only a matter of sifting thru a couple of quarts of matted hair, dust, party crumbs, lint, and some things I can't begin to describe. She often finds stuff I didnt even know I lost - it plays out as " Nice to see you back from the field. When I was vacuuming, I heard something rattle up the hose. Are you missing a part?"
