Joint Mechanics

Mortise and Tenon

One of the oldest recorded joint forms, used in Polish furniture since the medieval period. The tenon slides into the mortise and is held by wedges, drawboring, or adhesive.

Corner Joints

Dovetail Joint

The fan-shaped interlocking geometry of the dovetail resists tensile pull along the grain. Found extensively in traditional Polish chest (skrzynia) and drawer construction.

Structural Joints

Lap Joints

Half-lap, cross-lap, and end-lap joints are the backbone of Polish timber-frame construction. Their flat mating surfaces distribute load efficiently across structural members.

What This Site Covers

Cedar & Plain documents the geometry, structural behaviour, and historical context of the most common woodworking joints found in Poland — from rural folk furniture to urban cabinet-making traditions.

Each entry describes the joint's mechanics, the tools historically used to cut it, and its distribution across different Polish regional woodworking traditions (Mazovia, Silesia, Małopolska, Podlaskie).

The content draws on publicly available sources including Polish museum catalogues, the Muzeum Wsi Mazowieckiej collections, and academic publications on Polish vernacular architecture and furniture.
