  • Patent number: 5797708
    Abstract: A universal drill guide (10) comprising a base (12) being a frame-like configuration having a large central opening. A pair of elongated columns (14) are provided. A structure (16) is for pivotally mounting lower ends of the elongated columns (14) parallel to opposite sides of the base (12), so that the elongated columns (14) can go from upright positions to angled positions. A cross slide (18) rides upon the elongated columns (14). A bearing spindle assembly (20) is rotatively carried centrally within the cross slide (18). A guide chuck (22) is connected to the bearing spindle assembly (20) above the base (12). An adjustable cradle (24) is affixed to the cross slide (18) to hold an electric drill (26) in a stationary position, so that the drill chuck (28) can engage with the bearing spindle assembly (20) above the cross slide (18). A facility (30) is between the cross slide (18) and the elongated columns (14), for moving the cross slide (18) up and down on the elongated columns (14).
