1 - the edge base has no part for the corner to run along. I did it just to see if it would make the cube smoother
and the edge base goes around so that the corner can go under it. (basically a guhong edge base without the part for the corner to run along)
From my interpretation of this, the base of the corner should stay where its at while the base of the edge is not there. So, the base of the corners would slide around underneath the base of the edges. This would allow for a large edge base and a large corner base to be in the cube, just at different levels. (Keep in mind that the edges are held in by the centers on a more shallow level than the corner bases, as explained by the other numbers.)
In the CAD drawing that Ben posted, the corner base was moved to be more shallow and ride right alongside the base of the edge. This accomplishes nothing but having a more shallow mechanism in the cube, and it is not what he described.
I think that slowking agreed that that is what he was thinking without completely understanding what he was looking at.
Also, if it is based off the WeiLong, the corners should be pretty much just a stalk with a cap. They are like this on the WeiLong so that the corner doesn't interfere withe the center piece when reverse corner cutting. It is a very neat innovation, but it can cause corner twists if there is no mechanism to prevent them.
