Well thanks for the thoughts, but I already proved several times over that a cone is always a Oval section unless of course your cut is a V shaped cut not a regular planar cut of /

But if you can manufacture a nice parallelepiped out of pine wood of the size of a football for it is parallelepiped that have been my bugaboo throughout my life, would be of help. One with nice noticeable slanted angles on its sides.
