It tickled me that the latest issue of ShopNotes had a variation on a gizmo I've been using for awhile. The fence mounted block has a threaded insert and a through-hole. The table mounted piece has an enlarged hole to allow for the angle change when adjusting.
To use, I slide the fence to the position I'm after and tighten the side opposite the gizmo. I tighten down the 'knob end' of the gizmo and use the threaded rod to sneak up on the profile I'm after; tightening the gizmo end of the fence before making a pass. If I need to micro adjust, loosen the gizmo end of the fence, adjust by turning the gizmo knob and re-tighten.
On my fairly basic Rockler router table it makes micro adjusting easier and more repeatable than nudging the fence with my thumb. The threaded shaft backs out and the table piece comes off for storage. The fence mounted piece stays on as it does not interfere with 'normal' fence use. Obviously it isn't used all the time but, it helps me with locking drawer joints. . . I seem to be challenged with that joint.
