To determine the blade angle for raising the panels, draw a V4-inch square at the bottom corner of one piece, then mark a line from the inside face of the panel through the inside corner of the square to a point on the bottom edge Vs inch from the outside face (inset). Install a 6-inch-wide auxiliary wood fence, hold the panel against the fence and adjust the blade angle until it aligns with the marked line. Next, adjust the blade height until the outside tip of one tooth extends beyond the inside face of the panel, then clamp a guide block to the panel to ride along the top of the fence. Feed the panel into the blade, keeping it flush against the fence while pushing it forward with the guide block (right). Test-fit the cut end in a frame groove. If less than % inch of the panel enters the groove, move the fence a little closer to the blade and make another pass. Repeat the cut at the other end of the panel.
