Half and Bridled Scarf Joint transparent

When you need a beam longer than the sizes of your lumber, a scarf joint is the way to go. In this attractive half and bridled scarf joint, each beam is split longitudinally and connects to its partner with a mortise on one end and a tenon on the opposite end. That creates a super strong and durable connection. Hardwood pegs secure the joinery and add interest to any frame utilizing this type of joint.

  1. Evening.. I have been attempting to recreate each joint as it comes out, but I’m guessing at the dimensions. Of course, I’m working at about 1/4 scale, or so I would assume. It would be great if there were some dimensions given so that I could maintain scale when reducing – as it is, I’m just guessing. Blessings!

  2. So how does this compare with a undersquinted scarf with a wedge (and probably some grx screws or all-thread) or the double bladed scarf or th e others you also show on this site?

    1. Most of the time it is a personal preference which scarf joint you choose. An undersquinted scarf joint does resist twist in the timber better than others.

  3. NEED SCARF JOINT ADVICE
    I’m looking at 2×8 joists spanning 22 feet. They will sit on top parallel 6×8 beams spaced evenly (one end beam is in a tree using TABs in a tri-beam configuration, but that’s another story). I could use 11 or 12 foot 2x8s and have them overlap on top of the mid beam, bolted together for strength or go with a joint. Note: I plan to add joist bridging 2x3s to help with horizontal forces. Which scarf joint would make the most sense?
