Abstract: A shaper guard including an elongated guard body which is fixed to a pair of spaced fences and in front of the shaper head and spaced slightly above the work surface. An elongated planar guard panel is slidably received in a vertical guide slot within the guard body for limited vertical travel between a lower position in which the guard panel rests upon the work surface and an upper position resting on the top of a workpiece moving along the fences and beneath the guard body for operative engagement with the shaper head. The guard panel is biased downward solely by gravity.
