Hi:Using the fence as a stop block is dangerous, as it could trap a cut off between the blade and the fence. To use the fence as a stop block a short piece of wood may be used attached to the fence, only ahead of the blade. That allows room for the cut off piece after the cut has been made. A miter gauge and an aux. fence with stops is the safe way to go, when cross cutting on a table saw. Good luck Woodnut65
