A biscuit jointer cutter (20) for making segment shaped cuts by plunge cutting has a shoe assembly (24) reciprocally movable relative to a housing (22) containing a motor (66). The shoe assembly houses a cutter blade (28) rotatably driven by the motor, and has a front opening (30) through which the blade is movable in a forward direction for cutting and retractable in a rearward direction after cutting. A fence assembly (26) is mounted on the shoe assembly above the front opening. The fence assembly is adjustably movable upwardly and downwardly relative to the front opening by means of a rack and pinion mechanism (110, 116, 118) and also has a fence (76) adjustably pivotable through 90 degrees. A depth of cut adjustment mechanism (62) is operatively connected between the shoe assembly and the housing, and includes a movable rod (132) cooperative with a stop (146). The stop is a turret selectively rotatable about an axis eccentric of the rod and having recesses (150) of different axial length. A single spring (72) surrounds the rod and functions to both bias the blade to retract and to yieldably latch the turret stop in selected positions. The shoe assembly has a pivotally attached shoe (36) to expose a blade chamber 32 and the blade. |
