My guess is your talking of going old school on this, or caveman style. Wow your doing a large inside radius. You can layout your outside dimensions. Then drill holes around the perimeter. After the holes you can bandsaw from hole to hole. You can turn a bandsaw blade some, by backing up and forcing the blade to one side. Once finished you can belt sand the contour. The Triangled area also can be drilled, then if you have a bandsaw blade welder you can put the blade through the holes, weld the blade to length, etc...
Next best would be if you had access to a Bridgeport type mill. You could hold the part ridged, then punch holes along that nasty inside radius closer.
That part requires a bit of work even at a machine shop.
I used to surface grind aluminum, we used Crisco grease, the aluminum goes into the grease and not the wheel, however that is not extreme grinding.
