There are a few ways to join two rafters together at the peak, one way that we have illustrated before is the tongue and fork connection. In this detail a simple rafter to rafter mortise and tenon connection is used to simplify the process of cutting the joint. Please note that the tenon and mortise […]
While this fully housed mortise and tenon joint does not have the dramatic effect that a diminished housing does, it offers a simpler look with a more traditional feel. It is the style I chose in the construction of my home and I have no regrets.

This timber detail exploded view is of a collar beam which is a 4×4 connecting to a 4×6 rafter. The pitch is 12/12, and the tenon is set off the reference face 1 1/2″ and then 1 1/2″ thick, with a 3/4″ hardwood peg.
Here is an exploded view of a pair of purlin joints where they meet the rafter. Each frame design should be reviewed by an experienced timber framing engineer for the exact design of this joint. Loads, spans, type of wood, and possibly other factors will have to be considered when designing this joint. My examples are […]
This is an exploded view of a tongue and blind mortise at the ridge. The rafters are again 4×6 at 12/12 pitch with a 1 1/2″ tenon and mortise with a 3/4″ peg. The mortise doesn’t go all the way through the rafter and it doesn’t go all the way to the top end. This […]
This joint is known as the tongue and fork joint. Here is an exploded view of two 4×6 rafters at 12/12 pitch with 1 1/2″ tenon set 1 1/2″ off the reference side with a 3/4″ oak peg. These rough sawn rafters have also been reduced down to the next smaller 1/2″ in size at […]
Here is an exploded view of a scarf known as a timber frame bridle scarf. I haven’t personally cut this one, but my program offers it as a type of scarf, so I thought I’d show you. You should have your engineer decide on the peg placement. I just put in two to show possible […]
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.
Tie Beam Tenon to Post – This is an exploded view of a half dovetail tie beam tenon and the post it connects to. The housing in the post is a diminished haunch. The wedge is usually made of hardwood.
