Oh, man, that's a bummer! You ought be able to either make, or have made, a replacement crank though.
That's why when I want coffee, I just HOLLER as loud as can can "COFFEEEEE, WOMAN" Until she brings me some.
Or, more likely, til I get tired of yelling.
Haha, if i did that she would hit me so hard i would be in worse shape than that crank :-)
