I found that simply reversing my featherboard makes it function very well as a thin ripping jig to make repeated (thin) cuts on the non-fence side of the blade. The featherboard's hard side is simply set at the appropriate distance from the blade on the side opposite the fence. Then the fence is moved to support the larger "offcut" side as with a typical thin ripping jig, and you can make the cuts with push sticks as usual.
