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 […]
There are times that tenons will get in the way of each other, weakening the entire joinery area. This issue can be particularly common on a queen post truss where the tie beam, rafter, and post collide. A double mortise and tenon on top of the queen posts can solve the problem and is the […]
In this joinery example, we are detailing two variations of this double tenoned scarf joint. The first uses a hardwood wedge to drive the two pieces together and the other uses pegs. If you want or need a better method you can opt to use structural screws in place of the pegs. Both offer a […]
In this detail, we examine one way of approaching the lower strut to king post connection. In a king post truss, there are a couple of ways to attach the lower strut to the king post or lower assembly area. In this example, we are connecting the strut directly to the king post and not […]
This bladed scarf joint uses pegs to secure the two timbers together. Commonly utilized for either a sill plate or roof plate, if you add some all-thread steel rods or structural screws, it could be used in areas with light sustained tension. This joint is a half-lap joint with the addition of the tongues or […]
When designing a frame it is a general rule to try and not have too many timbers collide at one point. This is not always achievable. In this example we address one of the most common instances, when we need to connect four beams into a post. In both examples, we housed the beams into the […]
This post and beam connector plate detail shows how to use an Alumini Hidden Connector to join a timbered beam to a post. The connector is a piece of anodized aluminum in the shape of a “T”, in which one end gets screwed (in the case of this detail) with included Rothoblass HBS screws to the […]
In this joinery detail we join a post to a beam with a Timberlinx A095 Connector. There is a stub tenon to act as a locator and to ensure you cannot see through the beam and post after the timber dries a bit. It also has a diminished housing to increase the bearing surface for […]
When a timber frame load exerts outward thrust on this through tenon with a wedge, the force is well resisted and kept in check. The wedge draws the joint tighter, adding extra strength that you could not get with just pegs. The end of the tenon is rounded in this example, which is called an […]
During one of my first Timber Framers Guild Conferences, I heard a talk by Vico Von Voss about his various projects. He referred to square timbers as the male form and round timbers as the female form, and that you need to have a balance between the two in a frame. This was a powerful […]
