I have a Powermatic table saw and was having a hell of a time with the fence and spreader that came with it.  I could never properly align the blade guard and spreader. It was constantly binding.  It was especially bad when I tried to cut an angle.  I ultimately removed the guard.  Like many others I had wood bullets shoot back at me.  Board Buddies seem to be the answer.  The stock is pressed firmly to the table and I have had no kickback.
