Some of us don't have a jointer for machining straight edges on boards. If you're in that club, like me, you have probably screwed or clamped a straightedge to a board and jointed the edge with a flush-trim bit in a router. That's nothing new. But after doing it that way, I wanted a faster method that doesn't leave marks or holes in the board.

So I routed a series of parallel keyhole slots in a length of 12 " medium-density fiberboard. To several of the slots I added a small base, toggle clamp, T-bolt, and knob (hardware available at woodmagazine.com/jointjig). Now, I can quickly clamp down a workpiece of most any size and rout straight edges easily.
