Hammer Beam to Hammer Post
The hammer beam truss is more complex than the other types of trusses, but it allows for larger spans with shorter pieces of timber. Here we will take a look at the joinery of the hammer beam to hammer post in particular.

When you have two beams connecting into one post at the same height, you need to get creative in cutting the joints. The goal here is to make a secure connection without taking too much meat and strength out of the post. In this detail we show you how to accomplish that with an Offset Mortise and Tenon.

This example illustrates a very common assembly in timber framing. That is when a post connects to a tie beam (a horizontal beam, perpendicular to the ridge, that resists the spreading force of the roof onto the walls) or a plate.
We know that sometimes seeing it in action is better than a picture AND a thousand words – so we have scoured the web to find what we feel like are the best videos to illustrate cutting traditional mortise and tenon joinery.
If you are utilizing wooden pegs in your timber frame structure, we recommend close reading of Capacity of Pegged Connections, by Joe Miller, Ph.D. and P.E. Dr. Miller has devoted substantial study to the capacity of wood pegs as they … Tidbits – Capacity of Pegged Connections Read More »
Used primarily on plates and floor systems, this corner joint uses a mortise and tenon on one plate (red) and a tusk tenon on the opposing plate (purple). The opposing plate (purple) gets housed onto the plate for bearing. It …
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 …
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 …
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 …
