Too large a mortise, and you risk weakening the leg too skimpy a tenon, and you lose glue and mechanical strength.The ideal joint would have a large tenon with When deciding on the sizes of joinery components, the key is to attain a workable balance. tight-fitting mortise-and-tenon joint that locks apron to leg.The mortise and tenon is not only a good joint for tables, but the same principles also apply to design-ingjoints for cabinet doors and chairs. ![]() The best defense against these stresses is a well-designed. Also, as a tabletop that is fastened too tightly to the apron expands or shrinks, it can try to twist the joints. Shoving the table sideways or bumping against a leg gives the joints a mixture oftwisting forces. Leaning heavily on the top ofa table midpoint above the apron causes the joints to undergo a bending stress trying to lever them apart. srtch as when someone sits on the corner of a table. One is shear- a vertical load directly above ajoint. Leg-to-apron joints must withstand three different kinds of stress. When diat joint fails, the table falls apart. As the table-top shrinks and swells with seasonal changes, the movement works against the integrity ofthe table's structure.Where is all this stress felt? It's the leg-to-apron joint that holds a table together and gives it rigidity. To make matters worse, the very nature of wood adds to the stress.
