Anybody know where I can find plans for a "small" build-it-yourself rock crusher? Here's the situation: I've got plenty of good-sized rocks and a bunch of big rocks. I've also got numerous washouts and muddy spots in the driveway - which I'm slowly fixing. With all the available rocks on the place (simply too big for my use), I absolutely hate the thought of buying rock for the driveway! There's got to be a way to make big ones into little ones - and after having 2 strokes and a heart attack last year, it's not going to be a sledge hammer!
