Where your saw/router rides above the bottom row of stars, next to

top rows?

The saw bed plate outside edge rides against the 6" ply and the bottom
of the bed plate rides on the 12" ply.

The short side of the bed plate rides on the short extension and the
long side on the other.

The first pass will cut off the excess ply leaving an edge that will
duplicate the saw cut line which IMHO, makes it idiot proof (No need
to remember the offset which will be 1" on one side)
