Drill aligning holes in each piece of wood, then glue dowels in place for a tight joint. For this job to be done properly it usually requires a centering tool.
This is one of the most satisfying jobs to be done and it is also one that requires more patience and accuracy to cut. The interlocking features give the joint a lot more strength and also adds visual interest. This type of joint may be too hard for a beginner, as it needs precision cutting.
