Abstract: A method and apparatus for assembling a 2-piece skin door comprising a bottom skin (10) and a top skin (20) wherein each of the bottom and top skins' longitudinal edges have been bent and folded to complementarily hem each other in an interlocking manner to form a seam, the method including: holding the bottom skin in an upwardly open pan manner; holding the top skin in an inverted pan manner wherein its folded and hemmed edges are aligned with the corresponding edges of the bottom skin; and pushing the top skin to insert said top skin's folded edge into the bottom skin's corresponding folded edge to form said interlocking seam. The bottom skin may be held securely on a substantially planar surface with securing means. The top skin may be provided with means for pulling it in alignment towards the bottom skin by winch and cable with hook means.

Abstract: A wooden door with panel ribs (2.10, 2.12, 2.14) in the hollow core of the door wherein the ribs are made from scrap wood pieces. Since the scrap wood pieces are usually too short for this purpose, a method is also described that teaches means to connect the ribs made from the scrap wood pieces into useful lengths by the use of notches, connector blocks and conventional fasteners.
