A dowel joint is a butt joint reinforced with dowel rods. This joint is very neat and strong providing you use the strong glue. It is often used instead of a tenon joint if cost comes into consideration. Dowel joints must be a perfect 90 degrees or else the dowel will twist when assembled and it is hard to accurately drill the holes. Dowel joints are most commonly used to join frames, drawers and cabinets
The dovetail joint is made by interlocking two pieces of wood. It is the strongest of all woodworking joints, has a large gluing area, resists being pulled apart, looks attractive and holds together without glue. The dovetail joint can be fairly hard to mark out and cut and if badly done it loses all benefits.
Mortise and Tenon joint
The mortise and tenon is one of the most common joints used by woodworkers and is the traditional corner joint for sturdy frames. It is neat, strong, large area for gluing, it can`t wobble, difficult to pull out and most of the joint is hidden in the wood. It’s hard to mark and cut and has a poor resistance to tension, especially if badly fitted. It will connect at 90 degrees
