ABSTRACT:
A jig for forming multiple trusses at the same time is capable of clamping the trusses together to simultaneously adhere trimmable blocks to the truss so that the truss can be cut off to different lengths. The jig has floating spacers which translate forces applied to components of one truss on one side of the jig through all of the components of all other trusses in the jig. The same truss can be formed with different modular lengths by selection of a fixed dimension central opening and the number of web members to be used. All other dimensions of the web between upper and lower chords of the truss remain the same.
