The bed’s construction is mortise and tenon with a very unique tenon keeper that reminds me of a very large clothespin.
The posts are 3″ x 3″ ash, the side rails and end rails are a full 1″ thick hard maple,e and the accent wood is Peruvian Walnut.
The uniqueness is in the clothespin keepers that secure the side rail tenons to the vertical leg posts. The Pins are constructed with 3 pieces of wood. 2 pieces of Peruvian Walnut sandwiching a piece a Hard Maple. So as not to rely on the glued joints between the Walnut and Maple, The tapered contact surface between the pin and the side rail tenon is tapered so that the more force the is applied the more it pulls the pin’s walnut sides inward toward the tenon. The pin is tapered vertically to provide tightening adjustment through the contact edges are tapered edges to prevent the spreading forces that could be caused with increased load.
The side rail tenons extend through the end rail tenon (which have a relief cut in the tenon) to secure them
