The arms for Tom McLaughlin’s Modern Adirondack Chair are flat for about 7-1⁄2 in. at the front and angle down 12° from there. A miter cut makes this possible. To make the miter, Tom angles the tablesaw blade to 6° and crosscuts both ends of the joint. Since this is a butt joint, Tom uses splines for reinforcement. To make the spline grooves 90° to the miter, he holds each piece vertically on a sled and cuts them with the sawblade still at 6°. The grain of the splines should run in the same direction as that of the arms. When assembling this miter, Tom glues temporary clamping blocks to the arm to keep clamping pressure square across the joint.
