Simple Wood Joints: 4 Easy Ways To Join Wood For Beginners

Joinery is a key step in a woodworking project. But as a beginner woodworker advanced joinery is hard! Instead focus on mastering these simple wood joints.

wood joints often cause the most anxiety in beginner woodworkers. It can make or break a project literally. 

It’s happened to me before that after gluing up a project and thinking it was done, it fell apart the moment someone went to use it!

Using the right joint is key to a long-lasting item. And if you are a beginner, don’t try complex joints until you’ve done a few projects and become more confident of your skills.

The key to any joint is to maximize surface contact. What makes a glued joint strong is when you can increase the surface area of the glued joint.

So let’s look at the 4 simple wood joints that you can make.

Butt Joints Are Very Simple wood Joints

The most simple wood joints you can make are what is called butt joints. Literally this means butting up two pieces of wood and gluing them together.

This is the weakest joint and you should only use it without any reinforcement on small projects that don’t see much handling.

The weakest style of butt joint is when two pieces of wood are joined end grain to end grain. End grain has a tendency to absorb glue faster than the glue can bond the two pieces of wood together. You can use the trick of coating both end grains with glue, letting it dry and then using another coat of glue to glue the two pieces together.

A better butt joint is when you glue end grain to the long grain. Then you at least have one piece that glue won’t absorb into as much. Treat the end grain piece the same as above by coating it with glue and letting it dry.

The strongest butt joint is when you glue two pieces of wood side by side or face to face, so only long grain makes up the joint. This butt joint may not need any reinforcement although often some form of alignment aid is used. This type of butt joint is most often used for gluing up tabletops and other large slabs from individual boards.

The key to a strong butt joint are straight joints. These can be achieved by making sure all of your sawcuts are straight and at the right angle. When edge gluing for a table top you need to make sure that the long edges are perfectly flat. For this ideally you need a jointer although there are ways to joint an edge on a tablesaw or the old standby, a good sharp hand plane.

Lap Joints Are Very Strong Joints

A lap joint’s strength is in the huge surface area that is created. You’re essentially taking what would be a weak end grain to end grain or end grain to long grain joint and converting it to a surface to surface joint which is much stronger.

Lap joints can be created at the ends of boards or can be created in the middle. They are usually made face to face.

While the above examples are at right angles you can also use a lap joint to join boards end to end. But not that common of a practice.

Lap joints are relatively simple wood joints to create, especially if you have a table saw with a dado blade. A router would work too with a straight bit. It is also an easy joint to make with a backsaw and a chisel.

Dados Are Perfect Joints for Shelves

This is the traditional joint for shelves. By cutting a dado into the side of a cabinet, you provide a strong slot to slide in a shelf or divider.

Like a lap joint it provides more surface area for glue and doesn’t rely on just an end grain to surface grain joint. 

The other advantage of a dado joint is that the shelf sits on top of a horizontal surface (the side of the dado) which helps to support it. On the other hand an end grain to surface grain butt joint in the Butt Joint section above relies solely on the glue and any reinforcement you add. This puts great stress on the joint, especially if you put heavy items on the shel

Dados are essentially very narrow lap joints so the same cutting techniques can be used as with lap joints.

A groove is similar to a dado in that it is cut along the grain. Usually used on the bottom of the sides and ends of a drawer to capture the bottom of the drawer box.

A router plane is the best way to create dados and grooves by hand. Here’s one you can buy online at Amazon if you don’t have a local woodworking store:

Rabbets Provide a Greater Gluing area

A rabbet is essentially a dado along the edge of the board rather than across a board. It has the same benefits that a dado or lap joint have – a greater gluing surface.

Rabbets are often used to add a back to a cabinet. Or to connect the sides and ends of a drawer.

Like a dado they are simple wood joints that can be created using a table saw or router. If you are looking at using just hand tools, a rabbet plane makes the best rabbets, although it does take longer than other methods.

Here’s one you can get through Amazon if you don’t have a local woodworking store:

Reinforcing Simple wood Joints

Unlike traditional joinery such as dovetails or mortise and tenon joints, these simple wood joints can benefit from additional reinforcement to lock them in place and not rely solely on the glue used.

There are a few options for reinforcing a joint:

Using Dowels To Reinforce Simple woodworking Joints

These require precision drilled holes in both pieces being joined. They can either be through-drilled, which means you will see the dowel on the outside of the joint, or as in the image below, blind dowelled to hide the presence of the dowels.

For through dowels, a contrasting wood could be used as a design element in your project.

Or you can use dowels made from the same wood as the project to try and blend them in better. However they will always be somewhat visible since the dowel ends will be end-grain wood.

For blind dowels a dowel jig is the easiest way to ensure the dowels are aligned. Here’s the one I recommend:

Using Pegs To Reinforce Simple woodworking Joints

These are similar to dowels but are considered a design feature of the project as they are fully visible and stand proud of the surface of the wood. Pegs are often used in Shaker furniture.

They are more simple wood joints to make than dowels as you can drill through both pieces once glued up to insert the peg.

Screws Are the strongest Way to Reinforce Simple wood Joints

This is usually the strongest reinforcement you can add. Pre-drilling the holes is crucial to avoid any splitting especially at the edge of a piece of wood. Usually you should countersink screws to make them less visible or you can even counter-bore them so that they can be covered with a wood plug. Or use decorative screws (usually brass) as a design feature.

So no need to be intimidated by wood joints. They can be quite simple and still strong enough for regular use. Try these simple wood joints in your next projects and later you can still learn more advanced joinery techniques.
