Traditionally, when the young journeyman on the ‘Tour-de-France’ arrived at a new shop, he would build a pair of sawhorses for the obvious practical reasons, but also to indicate to the owner where he stood in his tour. The more complex he built it, the more time he had been studying Stereotomy – Art du Trait. This would in turn dictate to the owner the journeyman’s position in the company and the level of complexity that could be delegated to him. It would help the journeyman fix a suitable position in the company based on his skill, experience, and knowledge and understanding of Stereotomy. In this five day workshop students will build their own French Trestle; a specific design called The Moore Trestle. Students will learn to create 2D stereotomical drawings using the visuospatial part of the brain, a drafting square, a pencil and a ruler. Each student will be taught how to use this part of their mind to visualize in 3D, draw in 2D, and then construct their trestle. It is of the utmost pleasure for Patrick to share this very special and rare skill, known to very few North Americans. The knowledge of stereotomy is so important to human civilization that UNESCO has classified it on the List of the Intangible Cultural Heritage of Humanity as of 2009. A prerequisite of the course is to have knowledge, understanding, and use of hand tools (i.e. chisels, hand saws, layout tools).
