Scarf Joints

Stop-splayed and tabled scarf joint with under-squinted wedged transverse key. This type of scarf joint, which has been used since as early as 1250 A.D., is one of several typically found in Midwestern heavy timber structures. TDTW commonly uses it to join new and existing sections of tie beams, girts and rafter plates.

Scarf joint used to seamlessly join new replacement rafter plate to old.

 This face-halved and bladed and cogged scarf joint is here used to join a replacement post bottom to the undamaged portion of the original post. The earliest example of this scarf joint dates from 1575.
