ABSTRACT:
A power saw for rapid and repetitive accurate cutting of truss members on predetermined angles to insure tight fitting truss joints. The power saw is cycled vertically in a reciprocating mode and indexed at the limit of its respective up and downstrokes after being set at precise cutting angles. An adjustable saw indexing cylinder permits a wide range of web angle cuts. Workpiece clamps, mounted on a workpiece guide, coact with a web length stop to insure cutting webs of equal length and initiate the substantially automatic reciprocation and indexing of the saw acting on the workpiece.
