1. A miter saw comprising:
a base having a detent notch;
a table rotatably connectable to the base, the table being rotatable about a substantially vertical miter axis and having a substantially horizontal workpiece-supporting plane;
a pivoting assembly connected to the table;
a saw assembly supported by the pivoting assembly, the saw assembly comprising a blade, the blade being movable for a cutting operation downwardly from a first position where the blade is above the workpiece-supporting plane to a second position where a portion of the blade is below the workpiece-supporting plane;
a fence connected to the base assembly, the fence defining a fence plane perpendicular to the workpiece-supporting plane;
a locking mechanism disposed on the table, the locking mechanism being movable between an unlocked position and a locked position for selectively unlocking and locking the table for rotational movement relative to the base about the miter axis, the locking mechanism comprises a lock lever rotatably connected to the table, the lock lever having a handle for moving locking mechanism between the locked and unlocked positions, a rod connected to the lock lever, a rod extension slidingly movable towards the table, the rod extension contacting the rod, and a clamping plate disposed between the table and the rod extension, wherein the clamping plate contacts the base and the rod extension when the locking mechanism is in the locked position; and
a miter detent assembly for selectively engaging and disengaging the detent notch;
wherein a force applied by the clamping plate when the locking mechanism is in the locked position is aligned with at least one of the miter axis and a line along the intersection of blade and the workpiece-supporting plane.
