Abstract
A scroll or jigsaw of the walking beam type is disclosed in which the upper and lower beams or arms are of hollow, tubular construction so as to have sufficient rigidity to resist up and down vibrational movement, and so as to permit lateral cutting. The beams are mounted in a pair of identical die cast frame members, and the drive motor is mounted directly to the rear of the frame members. The motor is connected to the rear ends of the beams for reciprocably driving them. The frame members, together with the motor, are pivotally mounted relative to a base or table frame thereby to permit angling of the saw blade (as opposed to tilting the table) for bevel cuts.
