Clamp fence firmly to the tablesaw. Starting with the blade just barely protruding above the tabletop, feed stock firmly and carefully, using a hold-down jig and push-stick when appropriate. Keep stock firmly in contact with the table and the fence at all times. Raise the blade a little with each pass until the desired depth of cut is achieved.
Extra precautions must be taken to safeguard eyes, face, life & limb, as this cut is made without any safety guards in place!
