Woodworking Joints

There are many ways you can join two wood parts together in your carpentry work. A. Use the recommended pressure to squeeze adhesive out into a thin, continuous film between the wood layers. If the two wood pieces being joined have significantly different MC levels, then the final joint may be flawed. You can find qualilty Rabbeting router bits , Miter Lock Router bits and even Corner Lock Router Bits (also called drawer lock router bits ) that will help make creating these joints easy. The simplest of joints is a butt joint – so called because one piece of stock is butted up against another, then fixed in place, most commonly with nails or screws.

The woodworking joint is relatively easy to make if you know how to use a table saw or a wood router with a simple jig. It’s a fairly easy joint to construct and is strong, especially when secured with nails, screws or glue (Fig. I haven’t done a lot with toothpick bridges, but it seems to me that lap joints would be the way to go. I’d think that you would want as much overlap in the joints as you can get because the surface area of toothpicks is not much to begin with.


These anisotropic qualities are endemic to wood species, but they are triggered by changes to the wood’s MC All wood loses or gains moisture in an attempt to reach a balance or equilibrium with the conditions of the surrounding air. Dowel is also very useful for greatly increasing the strength of weaker woodwork joints such as the butt joint. Frame joints are right-angled, jointed frames common in furniture, boxes and many other types of assembly. Every place that two separate pieces of wood meet each other is considered to be a joint.

The tongue and groove joint is typically used when you are looking to join to square boards along a single long edge. Biscuits indeed are for alignment only as dowels are for more precision alignment in addition to strengthing two pieces of wood at a joint or seam. Although a little tricky to make, this is, hands down, about the strongest method of joining two pieces of wood together.

The main uses for this joint are to allow two pieces of stock to cross such that the joint is contained within the overall thickness of the material. The rebate joint is a very similar woodwork joint to the butt joint but the big difference between the two is that one of the ends of the timber has a groove cut out of it to create much better holding strength.

A single wedge (clearly visible in the top example above) or two opposing-angle wedges can be used to lock this joint in place. The main difference between the butt joint and the mitered butt joint is the angle of how the wooden boards meet. Because the two blocks of wood have matching ends, the dovetail joint would be able to tightly fit, making the piece of woodwork sturdy. This is because the wood’s oils will tend to migrate back to the surface of the wood where you removed some of the oils.
