November 30, 2006 4:43 pm. Iâve made bookcases in different widths with no supports between the gables. The widest one Iâve made has 86â³ wide shelves and exhibits zero sag. I make my stuff entirely out of MDF and never use screws or nails. As you probably know, MDF has no grain and canât support its own weight.
Continental shelves vary in width from 3 to 930 miles (5 to 1,500 kilometers). The average width worldwide is about 40 miles (64 kilometers). The widest shelves are in the Arctic Ocean off the northern coasts of Siberia and North America. Narrow shelves are found off the western coasts of North and South America.
