Abstract
A trailer bed or chassis including side rail extensions and center rail support posts serves to mount a wooden truss fabricating jig including laterally adjustable center rail sections and associated transverse arms for the support of truss lumber. An arrangement of permanent stops and swivel stops on the jig together with a truss peak locator and splice locator enable the setting up on the job site of a calibrated jig prior to placing the truss lumber thereon, resulting in a great savings of time in truss fabrication. Trusses are produced with precision and uniformity having improved quality and a wider range of truss sizes can be accommodated with the apparatus because of its versatility.
