When builders and architects say “timber frame” what they mean is that the structure of an entire building or maybe just a portion of it is supported primarily by large wooden timbers that are joined with pegs or by other types of decorative joinery. Almost always, the walls of the structure are on the outside of the […]
Every timber gets its name from where it is in the frame. This beam is between two posts. It holds them apart from the rafters pushing them in. It is called a “Straining Beam”. Here is an exploded view of one. Sometimes they have braces, sometimes they don’t. Usually it has a standard tenon on […]
Here is an exploded view of a half lap scarf joint with table. I suppose you could also use wedges between the tables to pull the scarf together. On half has been rotated to show another view.
The most basic scarf for joining two timbers together is the basic half lap joint. One timber has half its depth cut away on the top and one timber has half its depth cut away on the bottom and these two pieces lap over each other. This is an exploded view of a simple half lap […]
Another scarf joint that I have used is the “bladed timber frame scarf joint”. This drawing is of a 6″ x 10″ bladed scarf joint that we cut to create one long timber for an addition to an existing barn. The scarf is 2′ long and the tenons are 2 1/2″ thick and 4″ long. […]
Sometimes in timber framing it is necessary to join two timbers end to end. This joint is called a scarf joint. One of the most popular scarf joints is the stop splayed table scarf with wedges and under squinted butts. My drawing program is meant to be used to drive a CNC machine to cut joints; […]
Here is a see through view of a wedged half dovetail tie beam tenon and post joint.
This Dutch barn style through tenon is called an Anchor beam. Here is an exploded view of the tenon and post. Sometimes it is held in with pegs only, some times it has wedges on the outside of the post, some times it has both.
This is an exploded view of a 2″ knee brace tenon and mortise for a knee brace where it connects to a tie beam. The tie beam was rotated so that you can see into the mortise. The layout is 2″ off the face of the brace and then 2″ thick. Same with the mortise. […]
This is an exploded view of a brace tenon and its mortise. This brace is centered on the tie beam (which has been rotated so you can see into the mortise.) And the brace tenon is centered on the brace. This type of mortise and tenon joint is a little more complex to cut as […]
