Specifications for Exterior Woodworking Joint #10


Joint #10 utilizes a locking key somewhat simpler than the tenon keys of Joint #9. By increasing the tenon size itself to 1″ thickness, we can bore a 3/8″ diameter hole through the top of the stile and rail, on through the width of the tenon, and into the stock. A joint we’ll turn to on large gates of 2-1/4″ thickness extending in the 5′-6′ width range.
