Wedged Free Tenon

The original posts were through-tenoned into the eave sills, and in order to join the post to the gable sill, we had to rotate the tenon 90 degrees. We removed what remained of the original tenon, and cut a slot mortise in the bottom end of the post running parallel to the new gable sill. Then, we cut an extended mortise in the sill beneath the post, and drove a floating tenon into the two mortises. The tenon is secured in the sill by a wedge, driven into the rest of the extended mortise. While we try to avoid changing any joinery when making repairs, wedged joinery was also found in the king post truss system at the Abyssinian.
