Brian,
Your best bet is to mill the rectangular shape (leave .010" on the top for finishing!) then use a large radius ball mill and take small steps around the radii to generate the contour. Probably some program will be able to Gcode the profile, but you won't be cutting it with 12" long endmills. If you have autocad or something similar, offset a line the radius of your ball mill and then divide it into 5º increments and take the X-Y of the points where the radians intersect the offset line. This would be your program points. If the result is too coarse, you will need to go every 2º or finer. The material specd doesn't take too well to sanding, but will finish nice with a sharp cutter. Good Luck!
