ABSTRACT:
A scroll saw blade holding system comprises at least an upper scroll saw arm with a notched, forked end, a pair of plate members held together by a screw for clamping an end of a scroll saw blade, and a pivot pin, extending through the plate members and shaped to rest within the notch in the scroll saw arm. The pin preferably includes a longitudinally-extending, knife edge pivot point which allows the plate members and blade to pivot relative to the scroll saw arm. Also in a preferred embodiment, a blade retaining assembly is included and comprises a bracket attached to the saw arm and a lock knob and bolt positioned above the plate members for retaining the pin within the notch.
