Abstract: An apparatus for resurfacing a pair of guide plugs includes a turntable rotatably mounted on a frame having cutting tools interacting with resurfaceable guide plugs mounted on a reciprocating slide assembly which includes a guide support block adapted for reciprocating motion with respect to the cutting tools. The block has a pair of saw guides selectively attached thereto so as to be parallel to each other so that parallelism is maintained during the resurfacing process.

Abstract: First and second guide plates are engaged for linear sliding between them by a channel and rib engagement system. A grooving tool is carried by the plate associated with the rib, and the rib is in axial alignment with the tool head, such that the tool head can lead the rib. When a groove is being cut into a workpiece, the rib can follow the tool head into the cut groove to extend the range of the guide. Ribs of different size can be selected to coordinate with the tool and groove width. Filler strips similarly coordinate the channel width. An alternate or supplemental guide system joins the first plate to a series of accordion style hinged and foldable plates. These plates guide the first plate in linear movement as they fold or unfold.

Abstract: An apparatus for removing the dross ridges which are formed on the lower surface of a metal workpiece during torch cutting of the workpiece. The apparatus includes a support beam having generally flat upper and lower surfaces, and a cutting edge extending longitudinally along each of its four corners. The beam is positioned to extend across and below the workpiece path of travel, and the beam is rotatable between a neutral position wherein one of the upper and lower surfaces is just below the pass line of the workpiece, and opposite tilted positions in which one of the cutting edges engages and removes a dross ridge on the lower surface of the workpiece. Each of the cutting edges comprises a plurality of separately pivotable cutting blades, so that the cutting edge formed by the blades is able to closely conform to a non-linear surface contour of the workpiece.
