In order to raise panels on a table saw safely, you need a tall auxiliary fence secured to your rip fence. You could go to the trouble of making one with a brace that wraps around the fence beam, but my approach is faster and easier. I attached a narrow piece of plywood that matches the height of my rip fence to a wider one to form the new fence face.
Before fastening the two together, I drilled a pair of holes into the edge of the narrower piece to fit the mounting posts of two fence clamps. These clamps are inexpensive and available from rockler.com and other sources. The project took less than a half hour to make from scrap lumber.
