I need to profile (cut the edges) of some skinny boards.  I decided against balancing the router on top of said boards, cutting them freehand.  I like my fingers, and am confident I would shred them in such an attempt.

So I built this.  The legs are 2x2.  The carcass and fence are 1x8.  The surface is 1/4" MDF resting on 3/4" MDF.  The entire surface, save for a 6" hole for the router, is supported.  Best way I could think of to prevent sagging.  There is no joinery in this.  The frame pieces are simply glued-and-screwed to the legs.  The surface rests on interior shelf glued-and-pinned (5/4" brads) to the frame pieces.  The fence is glued-and-pinned.  Again, nothing even close to fancy.

The fence has 2" hole, bored at an angle, to hold the 2" vacuum hose from my shop-vac/dust-collector.  I worry about breathing dust and, with the furnace & water heater in the same room, I'm mildly concerned by the possibility of a dust explosion.  As you can seen in this image, the fence isn't attached to the table.  I just clamp it on, wherever I need it to be.





This is rough-and-ready work.  There are a few things about it that I'll change in the next version.  Chief among those, is that the bench isn't tall enough.  I made sure there was sufficient clearance to mount the router, but I failed to allow the space needed to remove it.  I must set it on it's side to change bits.  Not a big deal, really.
