Abstract
A clamp for securing an oversized work-piece to a milling machine table using the T-slot on the front surface of a Bridgeport-type milling machine table. The clamp, when attached to the T-slot, extends beyond the table and over it where it can be tightened down on a work-piece to hold it to the top surface of the table. The clamp includes a heel block and a clamp block held in spaced relation by a separation bolt and a tightening bolt. To mill an oversized work-piece, the clamp is inserted into the T-slot and then the separation distance of the clamp block to the heel block is adjusted by rotating the clamp block around the separation bolt until the separation distance is slightly wider than the thickness of the work-piece. The tightening bolt is then used to tighten the clamp onto the work-piece. The nose end of the heel block can be shaped to match the profile of the T-slot or can be modified to allow the nose to be rotated into the slot by rounding its corners. The blocks are formed to allow the tightening bolt to be positioned so that it is more or less close to the separation bolt in order to accommodate work-pieces of different sizes.
