ABSTRACT:
A plate joiner including a fence support, a drive, and a fence system. The fence support includes a cutter and a contact surface, which defines a cutter slot. The cutter is arranged and configured to protrude from fence support through cutter slot to make a plunge cut into a surface of a workpiece when the contact surface is pressed against the surface and the cutter is plunged into the workpiece by pushing on a rearward handle portion of the tool. The drive is arranged and configured to rotatably drive the cutter through a motor.
A preferred plate joiner is configured for substantially continuous adjustment of fence height while restraining lateral and tortional movement of the fence and providing an accurate measure of the height of the fence from any point in the thickness of the blade. The height adjustment system preferably includes an adjustment screw arranged and configured to provide substantially continuous adjustment of fence height and guide pins which restrain lateral and tortional movement of the fence at the height it is adjusted and locked. A preferred height adjustment system is employed in conjunction with a height gauge arranged and configured to be accurate each selected front fence angle.
