ABSTRACT:
In an apparatus for shearing multi-walled workpieces, such as metal framing studs, a pair of base supports are spaced relative to each other to define a blade gap therebetween, and a guillotine-like blade is slidably received within the gap for shearing the workpieces. A pair of first supports, each defining a plurality of first support surfaces, are each slidably mounted on a respective base support. A pair of second supports, each defining a plurality of second support surfaces, are also each slidably mounted on a respective base support, and the second supports are spaced apart from and face the first supports to thereby define an adjustable-width channel therebetween. Each of the first, second and base supports defines a blade-like edge located adjacent to and defining the blade gap. An elongated, multi-walled workpiece, such as a framing stud, is received within the channel, and the first and second support surfaces are each moved into contact with a respective wall of the workpiece to support the workpiece. The guillotine-like blade is then driven downwardly into engagement with the workpiece, and the V-shaped cutting edge of the blade cooperates with the blade-like edges of the adjustable supports to shear the workpiece along a line of contact.
