Guide panel makes for easy tablesaw tapers
Instead of reaching for a circular saw to taper a large workpiece, cut it on the tablesaw with this easy trick. After marking the cutline on your workpiece, cut a guide panel from MDF or plywood, making sure it's wide enough to overhang, as shown. Without moving the rip fence, adhere the guide panel to the workpiece along the cutline with double-faced tape. Then, run the panel along the fence to make the cut.
