DRILLING JIGS

 

Drilling a hole is simple, but there are times when a jig can save you time and frustration, especially when the hole must be located precisely, or at an exact angle. The center-drilling jig, for example, ensures that dowel joint holes will be centered in the edges of mating workpieces. The jig for drilling equally spaced holes on the drill press virtually eliminates the need for meas­uring and marking and guarantees con­sistently accurate results.

The tilting table and pocket hole jigs are both invaluable for boring the angled holes that are commonly used to attach tabletops and chair seats to legs and rads. The technique for drilling deep holes shown on page 67 will double your drill press’s quill stroke, allowing you to bore straight through thick stock without resorting to an extension bit.

 

A SELECTION OF DRILLING JIGS

 

Center-drilling jig (page 62)

Used with an electric drill to locate the center of a board edge’, dowels at the ends of the arm are butted against opposite board faces

 

Jig for boring equally spaced holes (page 64)

Used on drill to space holes uniformly

 

Pocket hole jig (page 66)

Clamped to drill press table to bore pocket holes; workpiece rests edge-down in angled cradle

 

V-block jig (page 65)

Holds cylindrical stock on drill press table

 

Tilting table jig (page 63)

Adjustable jig attached to drill press table for boring angled holes; workpiece lies face-down on top

 

Equipped with the jig shown at left, a drill press can bore a row of equally spaced holes quickly and accurately. The jig is simple to build from scrap wood and a short dowel.
