A workpiece holding device for a T-slotted machine table includes a locator block having a planar bottom surface, a mounting hole that intersects the bottom surface to define a center point, at least one workpiece locating surface disposed a predetermined distance from the center point, and a key protruding from the bottom surface at a second point offset a predetermined distance from the center point. The protruding portion of the key has a width substantially the same as the T-slot opening so as to slidably mount in the T-slot. A fastener extends through the mounting hole and secures the locator block to a T-nut slidably mounted in the T-slot. A clamp secured to the locator block clamps the workpiece to the locating surface of the locator block. A method of using the device is also disclosed.

[ What is claimed is:] [1.] A workpiece holding device for mounting a workpiece on a machine table having a planar surface thereon with a T-slot having a first leg intersecting and perpendicular to the planar surface and a second leg connected to the first leg, the second leg being spaced from and extending parallel to the planar surface, a T-nut being slidably mounted in the T-slot, the device comprising:a locator block including a planar bottom surface adapted to directly slidingly and matingly engage the planar surface of the machine table and a mounting hole having a central axis that intersects the bottom surface to define a first point, the block including at least one workpiece locating surface disposed a predetermined distance from the first point;a key protruding from the bottom surface of the locator block at a second point offset horizontally a predetermined distance from the first point, the key having a width substantially the same as the first leg of the T-slot so as to slidably mount in the first leg;a fastener extending through the mounting hole at the first point for securing the locator block to the T-nut;a clamping mechanism secured to the locator block for clamping the workpiece to the locating surface of the locator block; andthe predetermined distance between the first and second points being sufficient to insure that the key does not interfere with the T-nut when the locator block is secured to the T-nut.
