How Do You Cut A Lap Joint With A Stacked Dado Blade?
Lap joints can be found in all types of wood construction from framing to furniture pieces. When cut so that the two boards interlock (a half lap joint), they are strong and durable and the joint has very little movement. Half lap joints can be made in a variety of ways but the best results are often achieved using a stacked dado cutter and a table saw. Adjust the height of the stacked dado cutter to one-half the thickness of a board. To make a lap joint on the ends of the two boards, adjust the table saw fence so the distance between the fence and the outside edge of the widest part of the stacked dado cutter is the same as the width of one board. Hold one of the boards tightly against the miter gauge and make sure the end of the board meets the fence, then make a pass through the cutter. Make multiple passes through the dado cutter, moving the board to the left before each pass. Continue until reaching the end of the board. Follow the same procedure to cut the second board. Each boar
