3. Pocket-hole joinery - Wikipedia

   en.wikipedia.org/wiki/Pocket-hole_joinery

   Although the holes can be plugged the pocket hole may be considered unsightly when all sides of the joint are visible. It is not suitable for joining thin pieces of wood. The boards must have a minimum thickness of 10 to 15 mm (3 ⁄ 8 to 9 ⁄ 16 in). Pocket-hole joints are substantially weaker than joints which use dowels, or mortises. [8]

   Some woodworking joints employ mechanical fasteners, bindings, or adhesives, while others use only wood elements (such as dowels or plain mortise and tenon fittings). The characteristics of wooden joints—strength, flexibility, toughness, appearance, etc.—derive from the properties of the materials involved and the purpose of the joint.

7. Frame and panel - Wikipedia

   en.wikipedia.org/wiki/Frame_and_panel

   Panels are made slightly smaller than the available space within the frame to provide room for movement. Wood will expand and contract across the grain, and a wide panel made of solid wood could change width by a half of an inch, warping the door frame. By allowing the wood panel to float, it can expand and contract without damaging the door.
