This joint has become one of my favorite ways to join a principal rafter to a post. It offers a clean look and allows a plate to join to the post with a spline and a tie beam that can handle sustained tension. A basic mortise and tenon in the rafter and post with a diminished housing allows the tenon and rafter to bear directly on the post and then the through-bolted tie beam resists any outward thrust of the roof.
