In many pieces of furniture with tenon-joined parts, variable loads cause the destruction of glued joints. For the next repair, it is worth improving the connection like this, to increase its durability. Well, use a sharp chisel to cut the side edges of the socket at an angle into a trapezoidal shape. In turn, cut the plug crosswise in two places and insert two small wooden clinics into the cuts. After that, the tenon should be covered with glue and inserted into the socket in the second connected element and tapped firmly, and then press together while gluing.
