Rotary saw blades mounted on primary supports of a truss component cutting machine require angular adjustment to produce various required angle cuts of the truss components without changing the necessary lengths of the components. To achieve this result, the outer face of each rotary saw blade must pivot around a fixed reference axis lying on the outer face of the blade. The system provides a number of diverse precision adjustments of parts on which the saw blades are supported to assure that the blades in all angularly adjusted positions will have their outer faces remaining on the fixed reference pivot axis.
