Making a taped rip cut can be hard to do just right and especially when the workpiece is longish.
I had the occasion to make a thin taper about 38” long with only about 3/8” of taper. My favorite way to get an accurate taper is to spot glue a small bit of scrap on one edge of the piece and just slide it along the fence.
The method, however, requires that both ends of the piece be in contact with the rip fence all the way through the cut.
With most tablesaws and fences this won’t work. I needed an extra long fence. Of course, a good straight 2×4 would do, but what I had on hand wasn’t perfectly straight. What I did have, though, was a steel stud (2×4), the kind used in framing buildings.
I clamped the stud to the ripfence and, voila’, I now had an adequate length to do my taper method.
By the way, the steel stud can be clamped to the ripfence from it’s side lip, so there’s no problem with the clamp getting in the way.
I also use the metal framing stud as a long straight edge when breaking down sheet goods.
