Well, of troy, here are some everyday words for everyday things we might take for granted. Not exactly what you had in mind for unusual-sounding words, but these are fun to think about, too:
I like the name for the individual plates on a turtle's shell--and their various names depending upon where they're located on the carapace, which I also like--but I know you all already know that one fersure.
There are two t-words for the parts of the umbrella at the outmost stretching points: one that fits over the other one that the secures the stretch, both beginning with a 't'.
Parts of the hammer head? Human/animal names: the top, the lateral side, the flat front that hits what's being hammered, and the back part that looks like a double metal pony tail. Each of these has the name of a feature of an animal--most mammals would qualify.
