A project that I was working on included a top with beveled edges. When making these cuts at the table saw, a tall auxiliary fence is a must to stand the workpiece on edge. But even with the tall fence, the workpiece can sometimes tilt towards the blade, spoiling the results. The solution I came up with is a set of featherboard risers.
I attach a featherboard to the top of each riser and one to the bottom of the riser before the blade. This presses the workpiece firmly against the tall fence, ensuring a consistent cut. Don’t attach a featherboard to the base of the riser after the cut or the waste piece may pinch the blade.
