Concider using some of these mounted below the top.
I own a Black and Decker work mate, I've mounted tools like my planer, belt and disk sander, scroll saw to 3/4" plywood with a 2 X 2 cleat under it.
You just pick up the tool and clamp it to the table. This way your not getting saw dust all over your bench, it's also portable.
