By Glenda Taylor and Bob Vila. Wood joinery, as the term implies, refers to joining pieces of timber or lumber to create other structures. Crafting wood joints has its origins in antiquitythe dovetail joint, for instance, was used by ancient Egyptian sarcophagus buildersand the process remains essential to constructing or assembling many types of wood projects and fine furniture. The hallmark of skilled woodworking is the ability to create tight wood joints, where the edges blend seamlessly, making two joined pieces look like a single piece.

This requires correct usage of two basic woodworking tools : a jig and a fence. A jig guides cutting tools, such as saw blades or router bits, to ensure multiple precision cuts, while a fence is the rigid, straight edge on a power saw used to brace the material being cut. After all, the stronger the joints, the more long-lasting the results! A miter joint occurs when two end pieces are cut on angles and fitted together, commonly found in the corners of picture frames and the upper corners of some styles of doorway casing trim.

For a standard degree mitered corner, the two pieces are cut on opposite degree angles and fitted together. When installing trim, the pieces are glued at the seam and then fastened, via nails or screws, to the framing material in the wall.

When creating mitered corners for a freestanding object, such as a picture frame, the pieces are glued at the seam, and then additional finish nails or screws are used to fasten them together permanently to one another.

For freestanding woodworking projects, nearly all miter joints require both gluing and the use of additional fasteners. For example, you can create an octagonal mirror frame using eight pieces of wood cut on Best for: Making outside corners on door and window trim and creating decorative frames.

Pro tip: For tight miter joints that fit snugly leaving no visible gaps, use a miter sawa specialized power tool that allows the user to cut precise angles. In a basic butt joint, the square end of one piece butts into the side or the end of the other piece. The pieces are not attached to one another where they abut, but rather are fastened by nails or screws to framing lumber in the wall such as wall studs, which you can locate with a stud finder or without one.

Butt joints are often found on window and door trim where vertical trim pieces butt into a header horizontal trim piece at the top of the window or door or a horizontal window sill. A common variation on the basic butt joint is the mitered butt joint, which consists of cutting the ends of two pieces of wood often trim pieces on opposite angles so you can butt the mitered ends together and make them appear to be a single whole piece.

For example, instead of butting square ends of baseboard pieces together, which can leave a visible joint, one end is cut on a degree angle and the other end is back-cut at the same angle. An angled seam is less visible than a squared seam. Pro tip: For tight butt joints, use a chop saw, a tool designed to make precision square cuts. Photo: flickr. Lap joints are simply types of wood joints where two pieces of wood overlap.

The two most common variations are the full lap joint and the notched lap joint. A full lap joint , in which one board overlaps another and is then fastened together with screws or nails, is often used to construct the structural frame of a home.

Lapped joints are also used to reinforce other pieces of wood, such as lapping a diagonal piece of wood over vertical pickets in a gate. Like the full lap joint, a notched lap joint is created by overlapping two pieces, but the notched lap joint adds additional strength because both pieces of wood are notched and then fitted together at the notched sections.

The notch depth will vary, depending on the project. Best for: Structural framing or to reinforce pieces of wood that would otherwise tend to sag or warp. This will prevent confusion about whether to cut the top or bottom side of the pieces.

Mortise and tenon joints have been used to build hefty structures for thousands of years, and likely came about when ancient builders discovered they could create a stronger type of wood joint by tapering one end of a piece of wood and inserting it into a cavity carved in another piece of wood. The mortise is the cavity, and the tenon is the piece that fits into the mortise. Creating a successful mortise and tenon joint is an intermediate-to-advanced craftsman skill, but modern tools can make the process easier.

A router can be used to cut away excess wood, leaving a square or rectangular tenon projection, and a matching mortise can be cut out with a drill press or a plunge router. Best for: Joining perpendicular pieces, such as furniture legs. The dowel joint is similar to the mortise and tenon in that a projection is fitted into a socket to strengthen a joint.

The difference is that a dowel is a completely separate cylindrical object and both pieces of wood will need to have sockets. Dowels can also create a rustic look when the dowels contrast with the woodfor example, walnut dowels in oak construction. Best for: Wood construction where other fasteners are not desirable, such as bookcases, cabinetry, and handcrafted wood projects.

Tongue and groove joints are typically used to install materials that will lie flat, such as hardwood on floors or beadboard on walls and porch ceilings. Each board features a tongue, or ridge, running along one side and an indented groove running along the other side. Nails are inserted through the tongue, after which the grooved side of a second board is fitted over the tongue to conceal the nails.

While DIY tongues and grooves can be crafted along the sides of flat boards using a table saw and a shaper, today virtually all hardwood flooring and beadboard comes with tongues and grooves already cut. Your job will be to fit them together when it comes time to install. Best for: Hardwood flooring and beadboard installation. Pro tip: Install tongue and groove boards tightly against one another to prevent gaps. To do, tap the boards together with a rubber mallet as you install them or, in the case of hardwood flooring, by using a hardwood flooring nailer that sets the boards snugly together and neatly inserts nails at the same time.

Dovetail joints are found where the ends of two pieces of wood meet at a right angle, such as along the corners of drawer sides. The wedge-shaped assembly, which requires only glue and no other fasteners, is often a sign of quality workmanship. Once crafted only by hand, most dovetails are cut today using a router.

Best for: Assembling the sides of drawers or wood boxes and lids. Pro tip: If you plan to cut a lot of dovetails, invest in a dovetail jig for your router. Dovetail jigs are adjustable to let you cut sockets and tails that fit together perfectly. Disclosure: BobVila. You agree that BobVila. All rights reserved.
