The stop-splayed scarf joint with sallied abutments is a fun little twist on the standard stop-splayed scarf joint. In this case, the stops are sallied, or angled. This gives the stop faces of the joint additional strength without having to resort to complex cutting such as in bladed joints.
As with other timber frame joints, this one is further secured, usually with hardwood pegs, structural screws or bolted.
Special thanks to Michael Cuba for help on the historical naming of this scarf joint.
