Abstract: A coping bit capable of being easily modified to cut profiles having tenons of varying lengths is provided. The coping bit includes an axially extending primary drive shaft and a first cutting member fixed on the primary drive shaft. An axially extending secondary drive shaft having an upper and a lower portion is removably mounted on the primary drive shaft for rotation therewith, and a second cutting member is mounted on the secondary drive shaft in spaced relation to the first cutting member when the secondary drive shaft is mounted to the primary drive shaft.

Abstract: The process is used for making individual wood boards (52) from a plurality of wood pieces (10). In this process, wood pieces (10) of similar length and are joined side by side so as to form a panel (30). The panel (30) is then cut in a longitudinal direction with reference to the wood pieces (10) into panel sections (40) having a similar width. These panel sections (40) are jointed end to end to form a continuous wood board (50), which is then cut into individual wood boards (52). This process allows to manufacture wood boards (52) with a high degree of structural integrity and dimensional stability. It also allows to efficiently use small wood pieces (10) that could have been considered otherwise waste or low-grade materials, thereby increasing the yield of the sawmill.

Abstract: A process for the manufacturing of longitudinal profiles such and tongue and groove on boards wherein the process includes the steps; a) Moulding a substantial part of the profile cross-section by means of milling with a milling tool. b) Fine moulding undercuts in at least the groove of the board by means of broaching utilising at least one broaching tool.

Abstract: An apparatus for cutting dovetail joints comprises one or more trapezoidal mortising chisels mountable on a drill press, each trapezoidal mortising chisel having a trapezoidal cross sectional shape with a particular slope or “pitch” on its non-parallel sides. The trapezoidal mortising chisels are used to cut sockets in the tail board of a dovetail joints, where the sockets have a trapezoidal shape with sloped sides. A given slope can be selected for the sides of the sockets by selecting a trapezoidal mortising chisel having the given slope. A washer is also provided which is mountable about the tilt axis of a tiltable work table of the drill press. The washer has a set of holes located at an angle about the washer on either side of a reference radius, where the angle correspond to the slopes of the non-parallel sides of the trapezoidal mortising chisels.

Abstract: An adjustable bit for cutting tongues or grooves in a wooden workpiece that includes first and second cutter members adjustably mounted on a drive shaft, a plurality of spacer elements selectively mountable on the drive shaft to vary the axial spacing between the cutter members. At least some of the spacer elements preferably having varying thicknesses, and a ball bearing pilot member may be one of the spacer members. The cutter members may be formed for cutting a groove in the workpiece, or formed to cut a tongue in the workpiece.

Abstract: A method for manufacturing a wood veneer surfaced furniture top with a profiled edge, utilizing a special tool and process, which when used collectively, eliminates the need for certain relatively costly machinery and manufacturing processes.
