Types of Wood Joints

Whether it’s a big construction project like a house frame or a small-scale cabinet, every woodworking project that involves wood will inevitably require the challenge of connecting or joining two pieces of wood to form a larger structure.

The different types of wood joints and the optimal scenarios for using each type to achieve the best possible results,

1. Lap Wood Joint

Lap wood joint is commonly used for cabinet frames, making tables, temporary framing, and many more.

The wedge-shaped assembly that requires only glue and no other fasteners is often a sign of quality workmanship one or more wedge-shaped sockets are cut into one piece of wood and two pieces of wood are joined with clamped and glue cut on the other piece of wood. Nowadays the dovetail is cut with the use of a router.

6. Biscuit wood joint

Generally, the biscuit is made up of particleboard or something similar kind of material, and if you do this when you add glue it expands as it dries and creates even more secure holds.

Another method for joining boards along the edges and it cutting the slots and using beech wood wafers known as a biscuit for holding the boards in place.

This biscuit wood joint is a very useful modern woodworking joint, particularly to create table tops, relying on glue and the swelling of the biscuit for holding the boards in place.

7. Dado Wood Joints

This dado wood joint is used for three-sided channels cut across the grain of one piece of wood which is just wide enough for the other piece of wood to fit in, but mainly the dado joint is used for making drawers, cabinets, shelves, etc.

9. Pocket Wood Joint

This pocket wood joint involves cutting a slot and pre-drilling a pilot hole at an angle between two boards before connecting the two boards before connecting a two with a screw.

pre-drilling is required to be very accurate so it is typically accomplished by the use of a commercial jig also it works great for the face frame of cabinets and other similar applications where a lot of strength is not needed.

The pocket joint is mostly used in construction when you want to eliminate any screw on nail visibility, you can use also use butt joints instead of screwing the screw in on the end and you can screw them in at an angle.

10. Tongue And Groove Wood Joints
