A “retriever magnet” (about $15 at a boating store) or any other large magnet makes a handy, clamp-less stop block for repeated cuts on the table saw. Position it near the front edge of the table so that as you push the board with the miter gauge, the board loses contact with the magnet before hitting the blade. Don’t contact the board with the blade and the stop block at the same time or the board could kick back suddenly. Practice on a scrap and micro-adjust the cut by tapping on the magnet sideways with a hammer. To remove the magnet, grip it with both hands and turn it sideways.
