A plunge router [Fig 2, 27] is located with the spindle in a vertical axis above a support framework providing guidance for the router in the X and Y axes. The framework has a baseplate 1. Columns 10 are positioned at each corner linked by beams 11. Columns 10 and beams 11 may have slots therein to provide adjustment, the beams may be wider than the base plate. A carriage 15 is located between and may move parallel to the beams 11, adjustable stops 26 limit the traverse of the carriage. The carriage is constructed from a pair of flat plates [Fig 2, 16] guided in one axis by slider blocks [Fig 2, 18] and in the other axis by slider blocks located on a cradle plate [Figure 2, 20 and 21]. Workpiece 3 is clamped to a sub fixture or pallet 2 having a pair of dowel pins protruding from one edge of the fixture and locating with corresponding holes in upstanding locating plates [Fig 1b, 4 and 5]. In use a workpiece may be clamped to the pallet using threaded holes and T slots provided in the pallet. The pallet and the workpiece may then be located onto the base plate with the dowels engaging the holes to provide an accurate and repeatable location using clamp 6. In further embodiments the device may incorporate a copying device in 2 or 3 axis, [Figures 5a, 5b, 6 and 7b] using a Bowden cable and may be guided using a pantograph and stylus [Figure 8]. |
