Post-Apocalyptic Technology: Multimachine

"The MultiMachine is all-purpose open source machine tool that can be built inexpensively by a semi-skilled mechanic with common hand tools, from discarded car and truck parts, using only commonly available hand tools and no electricity. Its size can range from being small enough to fit in a closet to one a hundred times that size. The MultiMachine can accurately perform all the functions of an entire machine shop by itself." -wikipedia

The best documentation of the machine I have seen is at openfarmtech.org. My desire would be Multimachine aiding in the construction or maintenance of this kind of ride:
