Square Rule Timber Framing

The Course

A hands-on workshop learning how the North Americans were fabricating timber frames in the nineteenth century. Their system had evolved from the “melting pot” of European carpentry cultures combined with the straight timbers available from the virgin forests. However the roots of the new system can clearly be seen in the scribe rule practiced in Sussex in the 18th century. Students will line out and cut the timbers for a small frame that will be reared on the last day.

Square rule framing introduces students to a more contemporary framing method and design compared to the oak framing from scratch workshops. The workshop uses a range of local timbers, and the techniques used enable all the timbers to be calculated for length and bevels before cutting. This system embodies standardization and interchangeable parts as an integral feature. There is no test fitting of the joints and the first time the timbers go together is when we erect the frame! Most of the carpentry joints we will use are derived from the familiar English ones, but with some interesting variations.

The workshop techniques are related to a number of books published by North American authors such as Sobon, Schroeder and Benson, but also to local practice.
