This is straight out of Keith Rust's plans here:

I just wanted to share how even I could do this :
The desire is to be able to face joint a board that is wider than your jointer. First you need some parts:

I used 3/4" BB Ply to make some braces. The result is like a torsion box. You want to build this on a known flat reference surface:

The top and bottom are glued and screwed to the braces. I offset the panels by about 1/2", marked and drilled the holes. This prevents the screws from running into each other from opposite sides of the base (a little blurry on this one, it must have been getting late):

Gratuitous glue up shot. The panel and supports at the back of the bench are just setting there. This is not part of the assembly:

So here's the base assembly. The extra 5/16" hole at each end is for a dowel that will hold the bungee cord:
