A jig assembly includes jig body having a front side, a top side, a bottom side, a left side, and a right side, the top side and the bottom side being parallel to each other, the left side and the right side being parallel to each other, and the front side being perpendicular to the top side and bottom side. A lower carriage support is connected to a lower portion of the front side, and an upper carriage support is removably coupled to an upper portion of the front side. A pinion is connected to a top of the top side, the pinion configured to spin freely about an axle, and a pinion axle bracket is connected to a back of the front side above the pinion.

A mortise and tenon alignment jig includes a generally oblong body having a first straight longitudinal side, an opposing, second straight longitudinal side, a first semi-circular end portion connecting first ends of each of the first and second sides, and a second semi-circular end portion connecting second ends of each of the first and second sides. A top face has a lip extending outwardly of the body. A raised imprint surface is formed on a top of the top face. The imprint surface has a central gap and four orthogonally spaced arms extending outwardly from the central gap.

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.
