Dowel joints use a wooden peg to secure two boards together. A hole is drilled into the connecting ends and a dowel pin is inserted into the holes to securely connect the two parts. Described below are four common uses for dowel joints.

1 - Additional Strength

A dowel joint is especially effective in adding extra strength to the butt and miter joints. By drilling a hole into the ends of these types of joints and inserting each end of a small glued dowel into both holes, the joint becomes stronger.

2 - Position Maintenance

Some projects require parts to be glued and clamped together. Gluing and clamping can cause a poor alignment in joints. The addition of dowels to the joints will keep the parts in their proper position.

3 - Joint Pins

A dowel joint is also effective in creating joints that will have to endure the force of twisting. A dowel joint is also simpler and easier to add than some of the other tail-and-pin connections that would work in these situations.

4 – Dowel Joints Instead of Biscuit Joints

Biscuit joints are sometimes used in place of dowel connections. While the space required for a wood biscuit is easier to create than one for a dowel, the dowel itself is stronger than the biscuit. The material in a biscuit can also swell and cause a bulge in the joint material.
