Due to the pie shape of the ribs you will hardly get enough useless
material out of there to make it worth while. Think of a cast
aluminum spoked wheel. It is easy to figure out the weight
savings. Multiply the volume in cubic inches of material removed
by .1 which is the density of aluminum in pounds per cubic inch.
