Abstract
A method of making a joint, and the joint thereby produced, in which a first element comprised of low cohesion material is joined to another element of a structure, at a position at which opposed surfaces of the first element and the other element are adjacent and generally abutting, by driving at least one nail through the first element and into the other element at a nailing point at said position. Prior to driving the nail, a nailing cavity is formed adjacent the abutting surfaces at the nailing point that extends outwardly therefrom in the direction of the surfaces and that extends a substantial distance normal to the nail direction. The nailing cavity minimizes fracture of the low cohesion material and receives fractured fragments of low cohesion material that does break from the first element by penetration of the nail therethrough, thereby to prevent wedging of fractured material between the abutting surfaces of the elements that surround the nailing point which can result in a loose and insecure joint.
