Shopmade tablesaw inserts are easy and inexpensive to make. Made of plywood, these zero-clearance inserts help prevent tearout and keep narrow offcuts from getting wedged near the blade and thrown back at you. Tom Begnal gives a step-by-step tutorial on making an insert for your tablesaw. Once you've made one, you'll want several more -- one for each blade setup and dado width you use.
