One of the simplest ways to reinforce a butt joint (or a mortlse-and-tenon joint, for that matter) Is with through dowels. After the joint Is assembled and the glue has dried, simply drill dowel holes through the joint, using a drill press or a portable driii with a drilling guide. Then, apply glue to the ends of pieces of doweling and drive dowels through the holes with a mallet. Tip: Bevel the leading end of each dowel first with sandpaper. Leave about Vfc to */4 in. of the dowel protruding past the wood surface, then trim off the ends with a flush-cutting saw or file. Sand smooth. For a decorative effect, choose dowels made from a contrasting species of wood.

Dowel Effect

Dowel points

METAL DOWEL POINTS are Inserted into dowel holes on one work-piece. When the parts are lined up and pressed together the points create drHtlng points on the mating workpiece.

Toots for drilling guides for dowel joints

A DOWELING JIG makes drilling accurate dowel holes a breeze. The jig is set to match the thickness of the work-pieces, then fitted over each workpiece Individually to guide the drill bit and ensure that the dowel holes align when the workpieces are joined. See the step-by-step Instructions, previous page.

Dado & Rabbet Joints

Dado and rabbet joints are interlocking' joints used ior a variety of woodworking tasks. A dado is a square groove that's cut across the grain of a workpiece; a rabbet is a square groove that's cut along the edge of a workpiece; a groove cut with the grain in the field area of a workpiece is called either a groove or 'a plough. By combining these cuts you can make several types of interlocking joints, including dado joints, rabbet joints and dado/ rabbet joints.

Dado joints. Dado joints are used almost exclusively to joint horizontal panels or boards {usually shelves) to vertical panels or boards (usually cabinet sides). The interlocking fit, coupled with the enhanced gluing surface, makes the dado joint exceptionally strong. They can be cut with a router, straight bit and cutting guide, or on a table saw with a standard blade or, better still, a dado blade (See page 66).

Rabbet joints. Rabbet joints are a better alternative to butt joints for building boxes and carcases because the joints partially interlock. You'll commonly see them, or variations of a basic rabbet joint, used in bookcase construction to conceal the ends and edges of the back and top panels. Depending upon how the joints air- arranged, they can conceal most of the end grain. Creating

DADO & RABBET JOINTS interlock to add strength and increase glue surface. There ate many variations of the joint, [»chiding the dado joint, (above] the rabbet Joint (page 65, top left) and the combination dado/rabbet joint (page 65, top right).

recesses for back panels, top panels or glass panel inserts are also tasks that are commonly assigned to rabbet joints. Using a router, you can cut a rabbet with a straight bit arid cutting guide, nr you can cut one freehand by following the edge of the workpiece with a piloted rabbet bit. A table saw, with or without a dado blade, is another option.

Dado/rabbet joints. Dado/rabbet joints combine the enhanced gluing area of a rabbet with Ihr interlocking characteristics of a dado or groove to form joints that are very resistant to failure from racking or shear. Dado/rabbet joints take two forms, depending on their intended purpose. One

How to make dado/rabbet joints

TEST-FIT THE JOINT and adjust the thickness of the rabbet ledge by trimming, if needed. Apply glue to both surfaces, then assemble and clamp the joint.

CUT THE DADOES FIRST at the joint locations, using a straight router bit or a table saw and dado-blade set. Measure the dadoes and use the measurements as a guide for cutting rabbets with lips that fit exactly into the dadoes (In the photo above, a guide block Is damped to the router base and the rabbet cut Is made with a straight bit). Make sure the rabbeted ends will not extend more than halfway into the dadoed board.

L Rabbet Joint

Interlocking Rabbet Joint

style features a rabbet, with a tongue half the thickness of the workpiece that fits into a matching dado or groove. This joint is used commonly to fasten shelves to upright standards, such as bookcases. The ends of the shelves receive the rabbets, while the standards are dadoed. Another less com mon use of this joint is for frame and panel door»— the rabbet is cut around the four edges of the panel and the dado or groove is centered around the inside edges of the frame. The panel with the rabbet tongues faces out, which leaves a decorative reveal between the frame and the panel.
