Wood joinery, a technique employed for over 5,000 years, has empowered humanity to construct shelters and edifices using solely wood. While straightforward straight joints suffice for basic linear structures, challenges arise when dealing with curved or three-dimensionally complex designs. What strategies do we employ when our designs demand curved complexity or three-dimensional forms? Students will embark on a journey to master the art of crafting a curved scarf joint using basic hand tools and the principles of stereotomy. Participants will first draft the stereotomical drawing by hand, providing essential layout for laying out the intricate double-curved joint. Subsequently, they will execute the cutting and assembly of this complex joint, gaining practical expertise in the process.
