Nothing beats the look and strength of an undersquinted scarf joint with a wedge. In this detail we illustrate three types of methods to connect the two beams and joints together. Please note that the preferred method for scarf joint placement is over a knee brace, not over a post. Click Images for Slideshow and Larger Images This example […]
This detail was created out of a need to join a timber frame corbel, post and plate together in a hexagonal structure that will serve as a gate hut for a local golf club. In this case the corbel is not carrying any gravity loads but lateral loads. I saw an opportunity to make the […]
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 […]
This is an exploded view of a 3″x5″ knee brace tenon and mortise, with tenon layout of 1 1/2″ off the face and 1 1/2″ thick, and its mortise in a tie beam. The peg is 3/4″ in diameter and it’s placement is 1 1/2″ off the shoulder and 2″ off the bearing end. The […]
This picture shows some of the names of the knee brace tenon. This tenon is either 2″ off the layout face or 1 1/2″ off. Either way the names would be the same.
Often a spline is used in a timber frame to reduce the amount of wood that is taken from a post or beam, this particular connection detail has two knee braces flanking the spline.
