Abstract: A bottle interlock assembly is provided in which the bottles remain connected together during any striking in any axial orientation. The bottles may be separated and reassembled to refill and/or replace one or both of the bottles. Such a stable bottle connection or interlock assembly preferably has two distinct and different connection assemblies, e.g., a slide and snap. A first interlock connection may include a projection and correspondingly shaped slot to slidingly receive the projection. A second interlock connection may include a protrusion and a correspondingly shaped recess adapted to receive the protrusion or snap together. The first interlock connection prevents the bottles from separating along the x-axis while the second interlock connection prevents the bottles from slidingly separating along the y-axis. The combination of the first and second interlocking connections accurately aligns and keeps the bottles together without the need for additional components.

Abstract: A method of constructing trusses includes providing a laser jigging system that projects the location of the jigging hardware so that an operator can easily, quickly, and precisely position the jigging hardware on the work-surface prior to positioning any truss members on the work-surface is described. More particularly, the system projects puck and other jigging hardware alignment or location guides on the table work-surface. With the alignment guides projected on the table, the pucks and other jigging hardware are located in alignment with the projected guides, and secured to the table. The truss members are located on the table in accordance with the pattern defined by the jigging, and connector plates are then engaged with the truss members.
