Another thought for clamping 2x4 sheets on the perimeter is that you need to make certain the center stays in contact with the bed. If you use an upcut bit then the center will flex upward and that could lead to disaster very quickly. That's one area where a vacuum table would be beneficial or at least a combination of clamps and vacuum.
I've cut 1/4" and 3/4" but they were smaller pieces, less than a square foot, so clamping on the outside was fine.
