Abstract
Disclosed is a plate joiner having a quiet drive. The joiner comprises a base having a guide surface with a cutter slot. A cutter is normally housed in the base, the cutter having a drive shaft with an axis oriented substantially parallel to the guide surface and substantially perpendicular to the cutter slot. The joiner comprises a motor for driving the cutter and a system for causing the cutter to protrude from the base through the cutter slot and to make a plunge cut into a joint surface of a workpiece when the guide surface of the base is pressed aganist the joint surface. The present plate joiner further comprises a quiet drive system for rotating the cutter without the use of gears between the output shaft of the motor and the drive shaft of the cutter.
