How to Build a Classic Westport Chair

Trim the seat blank using a jigsaw. Cut the four long lines with the blade at 90 degrees, but bevel-cut the two short connecting lines with the saw set to 12 degrees, angled toward the back legs. Make the backrest the same way: Join the two boards with battens, mark the cutlines, and cut the piece to shape. Note that the long edge of each notch must be beveled at 12 degrees, angling in toward the rear of the chair, for the back legs to sit flat against the backrest.
