The saw you bought is the same saw Norm used on NYW. It could run either 10", or 12" blades (with bushing.) Bushings can be had for around $1.50 each, the last time I bought some. DeWalt Service Centers, and Freud have them, along with others. Over the years, Delta used several motors on your saw. Looks like you are missing lower "leaf guards." Unfortunately, new Delta parts are impossible to find, but you make your own using some polycarbonate. The AMAZING thing about your saw is Delta listed it as PORTABLE, even though it weighs in at 300#. Portable meant, that with the table removed, two guys could carry it through a 3-0' door.
