It’s time again to make some zero clearance table saw throat plates. I planed a piece of oak to the thickness of the existing throat plates for my Powermatic 72 and 66. I shaped the pieces to fit snugly in each table saw. The Powermatic 72 has a rectangular throat plate and the Powermatic 66 has an oval shaped throat plate. I cut the slot for the blade by raising the blade up through the wood as it was being held down by the fence. I then cut the slot further to insert a small piece of wood as a fin. This fin is the same width as the slot and the blade, and acts as a riving knife. It helps to keep the wood from binding on the blade and up against the fence.
