Scale′board-plane.
(Joinery.) One for planing off wide chips, for fruit, hat, and bonnet boxes and other objects. It is a plane the width of a board, is loaded with weights, and dragged or driven over the surface of the board or balk, the degree of protrusion of the plane-iron determining the thickness of the scale. A converse arrangement is that in which the plane is fixed and the board is driven past it.
