A rotary feeder mechanism is provided for a stringer notcher wherein the feeder includes opposing pairs of pusher arms with one pusher arm of each pair being located on opposing sides of a magazine holding a vertically stacked supply of stringers to uniformly move the lowermost stringer onto a work table. The opposing pusher arms are eccentrically mounted on opposite sides of a rotary drive shaft. A control link is connected to each pusher arm to maintain the orientation of the distal ends of the pusher arms in a selected orientation during rotational movement. As one pusher arm moves a stringer onto the work table, the next vertically stacked stringer rests on the top surface of the stringer to be eased onto the bottom of the magazine as the pusher arm retracts below the level of the work table for the opposing pusher arm to then engage the next stringer.

A mortise and tenon jig includes a base plate, a router support plate attached to an upper surface of the base plate such that the router support plate includes an opening, and a guide attached to the router support plate. The guide may include a first end and a second end. The first end includes a mortise guide surface, and the second end includes a tenon guide surface. The mortise and tenon jig also includes a first configuration where the mortise guide surface is aligned with the opening and a second configuration where the tenon guide surface is aligned with the opening.

A working control module of a woodworking tenoning machine is configured to work a wood material in a desired tenoning shape by using a human machine interface (HMI). The working control module contains: a tool selection module, a tenoning shape selection module, a model calculation module, a three-dimensional (3D) drawing module, a working path module, a feeding module, a working module, and a material returning module. Thereby, the user is capable of selecting the desired tenon shape, inputting the at least one characteristic variable of the desired tenon shape to draw, view or amend the 3D model by using the HMI of the working control module. After confirming the 3D model, the wood material is worked in the desired tenon shape automatically, thus enhancing working efficiency and working accuracy.

The invention relates to a method for forming an elongate cut-out (2), which has a varying transverse dimension in the longitudinal direction, in a workpiece (1), which is preferably composed of wood, wood materials, plastic, or the like at least in some segments, wherein the method comprises plunging a machining device into the workpiece (I), which machining device has an adjustable machining diameter; moving the machining device and the workpiece in relation to each other (II); adjusting the machining diameter of the machining device (III); and removing the machining device from the workpiece (IV).

A handheld mortise forming device includes a base unit having a first support extending parallel to a first axis. The first support includes first and second working ends. A first sidewall and a second sidewall are connected to the first support. One of two connecting units is rotatably mounted to the first sidewall. The other connecting unit is rotatably mounted to the second sidewall. A second support extends parallel to the first axis and is connected to the two connecting units. The second support is rotatable relative to the first and second sidewalls and includes an abutting face. A clamping unit includes a pressing member located on a side of the second support adjacent to the abutting face. The pressing member can clamp lumber. The pressing member is jointly rotatable with the second support and is switchable between the first working end and the second working end.

A notch cutter according to the present invention generally comprises a cutting head driven by a motor to cut a notch parallel to the wood grain of a board. The board is held in place by a board frame, while wood shavings are funneled away from the notch cutter through an exhaust. Pneumatic tubes may be used to facilitate linear movement of the cutting head and motor along guide rails. The motor and guide rails are protected by a casing that may include beams and a stabilizer.
