Abstract
A flush bolt boring jig is rigidly attached to a drill. The drill has a bit which is the length of the bore to be formed in the door. The jig holds the drill rigidly so the bore being drilled in the door is parallel to the free end of the door. This is done by tracks mounted by clamps in such a way that the tracks are parallel to the free end of the door. The jig is attached to a pair of slide tubes which slide on the tracks. Since the drill is attached to the jig, as the hole in the door deepens, the drill moving with the slide tubes over the tracks moves in a straight line so that the bore being formed is exactly parallel to the free end of the door.
