Proper crosscutting. Don't use the rip fence as a stop block for crosscutting. The better way to make repetitive crosscuts on a table saw is with a sled and a double-clamped stop block.

When stops are used, the wood captured between the stop and the blade must be held securely. For example, on a chop saw the wood between the stop and the blade must be held firm and still until the blade comes to a complete stop in the down position. 4. Be aware of the rotation of cutters, bits or blades when choosing the location of a stop. For example, whenever using stops on the drill press, you need to remember that the chuck spins in a clockwise direction so the pulling or kicking force will be in that same direction. 5.

These types of stops must always be tight and can be used as a way to prevent kickback when the cutter fully engages the wood.
