WOW! This is a wonderfully crafted insert. You DON'T even have to think about replacing the OEM (especially if it like my Powermatic model 66  talble saw OEM insert) as this is FAR better! It is nice to see a finely crafted product made here. I am kicking myself for putting up with the OEM insert for years. It is a piece of *#&! compared to this. I can't believe in retrospect, that Powermatic supplied such a hunk o junk with a very high end saw. This is the best thing since sliced white bread as they say. Push the "Add to Cart" NOW!
