I though of this idea of a totally adjustable tapering sled. Very easy to make and doesn't take much time at all. The pics show just about everything you need to know about it including T-bolts and T-slots for the adjustability part. It runs in the miter slot just like a sled. I've thought about the lazy idea of 3 or so toggle clamps for different thicknesses of wood. This wood save time adjusting a single toggle clamp. When tapering 4 sides of a leg I just use the wedge that is cut off the leg to hold it square in the sled.
