A machine for creating holes in a structural angle, including parallel plates including (1) an earth plate perpendicular to an axial direction and positionable at a fixed position relative to the structural angle, (2) a top plate mounting a workpiece tool, (3) a bottom plate spaced a fixed distance from the top plate, both plates being supported for axial movement relative to the earth plate, and (4) a support plate between the earth plate and the top plate and supported for axial movement relative to the earth plate. The support plate is biased toward the top plate and away from the earth plate. A first stop limits movement of the bottom plate toward the earth plate and a second stop limits movement of the support plate away from the earth plate. A drive selectively moves the support and bottom plates axially away from each other.
