The client had a vision of the design, and together we chiseled that down to a nicely proportioned king-sized bed that fits well within the space and complements the other furnishings-- the bedroom has tall ceilings and furnishings that are relatively short, so the low slung design of the bed is well suited to the feel of the room. To me, the appeal of the design is in it's simplicity and that the colors and textures of the woods are more complimentary than contrasting; and, the depth of color in the eastern cherry and fiddleback grain in the western maple collaborate beautifully. Through tenons of any size are a challenge, and with legs more than three inches thick, both parts of the joint are problematic to cut. The mortise cut on the exposed face of the legs is even more critical because any irregularity in the mortise will be visible against the side of the tenon as it protrudes from the leg (while the shoulder of the rail on the inside leg face covers the perimeter of the mortise, so at least one side allows for a little buffer if the chisel operator happens to loose focus and make an errant cut). Because the legs are thicker than the mortise bit is long, the mortise had to be cut from both sides to bore all the way through. (Although, I imagine it would make sense to do it this way regardless, since the tear out of a mortising bit on the back side of a leg would be ragged). A few adjustments to get the mortise machine set square and true made the holes line up nicely. For the tenons, it took longer to build a jig capable of handling a 10" wide tenon than it took to cut the tenons, but it was time well spent because the cuts were precise and the jig will be used again. Wedges in the tenon ends provide for positive attachment between the legs and rails, and minimize the need for glue. Beds carry significant weight-- weight that sometimes moves around rapidly-- and it is distributed across only a few joints, so the mechanical strength provided by the wedge in a through tenon adds extra durability to an already strong joint. While test fitting all the pieces, I marked where the tenon protruded from the leg, and chamfered the ends with a chisel while disassembled. After the glue-up, it was quick to trim the wedges and touch up the exposed tenon end.
