Kirk, I do this often in my shop. I keep many pieces of sacrificial aluminum plate around. On parts with a profile I drill all the holes in the part while square then use at least two holes in the part and then mount it to the sacrificial plate which is mounted into the vise. Then I cut the profiles going 0.025 - 0.050 deeper than the thickness of the plate(depends on the radius of the edge of my cutter).
