Or maybe that should be horse-powered router. Lewis Stepp of the Craftsman Gallery and WoodRat seller posted a thread on his forum with some pictures from an Amish fellow's WoodRat and the modification he made to his DW625 router so that it can be driven by a couple of horses instead of using electricity. Very ingenious setup.
Unfortunately, due to the SMC TOS, I can't post a link to the thread so you're on your own to find it.
