Claims
- 1. A floorboard comprising:
- two tongue and groove wooden strips, each having top and bottom surfaces defining a predetermined thickness therebetween, the strips arranged end to end and having a joining line defined by the connection between the strips, a bottom portion of the joining line adjacent the bottom surfaces of the strips being vertical and in vertical alignment with an upper portion of the joining line adjacent the upper surfaces of the strips, and a fingerjoint connection between the upper and lower portions of the joining line defined by interleaved fingers, thereby providing a sandable work surface between the top surfaces of the joined strips and a top portion of the finger joint connection.
- 2. The floorboard of claim 1 wherein the wear surface is at least 3/16".
- 3. A composite floorboard comprising:
- two wooden strips, each having top and bottom surfaces defining a predetermined thickness therebetween, the strips arranged end to end and having a joining line defined by the connection between the strips, a bottom portion of the joining line adjacent the bottom surfaces of the strips being vertical and in vertical alignment with an upper portion of the joining line adjacent the upper surfaces of the strips, and a finger joint connection between the upper and lower portions of the joining line defined by interleaved fingers, thereby providing a sandable wear surface between the top surfaces of the joined strips and a top portion of the finger joint connection; and
- a layer of material laminated to the bottom surfaces of the wooden strips thereby to define a composite floorboard of uniform width, the floorboard having one side surface with a horizontal tongue therealong and another side surface with a horizontal groove therealong.
- 4. A method of manufacturing a floorboard comprising the steps of:
- forming horizontally extending fingers in the opposing ends of two pieces of wood, the pieces each having first and second surfaces defining a uniform predetermined thickness therebetween; and
- interleaving the fingers to joint and secure the two pieces of wood into a composite piece having a joining line defined by the connection between the two pieces of wood, a first portion of the joining line adjacent one of the first and second surfaces being vertical and in vertical alignment with a second portion of the joining line adjacent the other of the first and second surfaces, and a finger joint connection between the first and second portions of the joining line defined by the interleaved fingers, thereby to define a sandable region between the first and second surfaces of the two pieces of wood and the finger joint connection.
- 5. The method of claim 4 further comprising the steps of:
- filleting the composite piece longitudinally along a plane mid-way between the top and bottom surfaces thereof and through the finger joint connection, thereby to form two composite sections each of a thickness which is about half the thickness of the composite piece, each composite section having a portion of the finger joint connection residing adjacent a filleted surface thereof; and
- adhering the filleted surface of at least one of the composite sections to a support member, thereby to produce a laminated floorboard.
- 6. A method of manufacturing a floorboard comprising the steps of:
- (a) forming horizontally extending fingers in the opposing ends of two pieces of wood, the pieces each having first and second parallel surfaces defining a uniform predetermined thickness therebetween;
- (b) interleaving the fingers to joint and secure the two pieces of wood into a composite piece having a joining line defined by the connection between the two pieces of wood, a first portion of the joining line adjacent one of the first and second surfaces being vertical and in vertical alignment with a second portion of the joining line adjacent the other of the first and second surfaces, a finger joint connection between the first and second portions of the joining line defined by the interleaved fingers, and a parallel mid-plane through the composite piece, thereby to define, for each of the first and second surfaces, a sandable region located adjacent thereto;
- (c) filleting the composite piece along the parallel mid-plane between the finger joint connection to form two intermediate composite pieces, each intermediate composite piece having a pair of spaced parallel external surfaces with a portion of the finger joint connection residing therebetween;
- (d) filleting at least one of the intermediate composite pieces midway between the two external surfaces and through the portion of the finger joint connection residing therebetween, thereby to form a pair of composite sections; and
- (e) adhering at least one of the composite sections to a support member to produce a laminated floorboard, the laminated floorboard having an upper unadhered wear surface corresponding to one of the external surfaces formed during step (c), and a respective portion of the finger joint connection spaced therefrom to define a sandable wear layer adjacent the upper wear surface.
