There are many ways to join pieces of wood, but mortise and tenon joints are the standard against which most alternatives are measured. In this comprehensive video (15 minutes), University of Rio Grande program director Eric Matson explains how mortise and tenon joints are used in typical post-and-rail construction — the type of construction often used in high-quality chairs, tables, and beds. In these applications, vertical posts (or legs) are joined with horizontal rails (or aprons). It’s the perfect application for this traditional joint.

In this video, Eric deconstructs a sample side table to show us how high-quality furniture is designed and built. Learn how to layout mortises for maximum strength, how to incorporate and work with split tenons, how to mark-up twin tenoned mortises, and how to account for reveals, offsets, and non-flush designs. Eric’s systematic approach minimizes errors and helps make layout and construction more efficient. For me, that’s the key point; understanding what makes for consistent, repeatable, quality joints. Armed with the information in this video and careful step-by-step application of what you’ve learned, you can craft better, stronger, faster joints. — (15.5 Minute Woodworking Video)
