A portable drill guide and method are disclosed for use primarily with hand held power drills having a pistol-type hand grip. The drill guide includes a mounting assembly and an operational guide assembly, the mounting assembly having a tool support bracket with a clamping band and resilient gripping limbs. The operational guide assembly includes a support arm bracket having the tool support bracket connected therewith and a support arm extending therefrom at an angle normal to the mounting assembly, a pair of interface guide posts with retainers, and an interface tensioning mechanism including a slotted two level shaft. An interface, a sufficient length of durable webbing or strap for example, is engagable around a workpiece and the guide posts beneath the retainers, and is operably associable with the tensioning mechanism. |
