The secret to this method is so simple yet extremely effective. The key is to make a custom spacer that is the exact same thickness as your table saw blade. Many blades are 1/8” so you could easily use some 1/8 plywood. For thin kerf blades, you’ll need to make a spacer to spec. woodworking projects woodworking tools woodworking supplies woodworking basics

Find a small piece of wood, like a 1×2. Using your crosscut sled, start by squaring off the end, then slice off a tiny piece roughly 1/8” thick. woodworking projects woodworking tools woodworking supplies woodworking basics

Remove the crosscut sled, and raise your saw blade. Place a piece of scrap birch plywood on each side of the blade (like a saw blade sandwich). Try to fit the spacer into the sandwich (spoiler: it likely won’t fit). Lay some sandpaper on a flat surface and sand the faces down until the spacer fits between the plywood boards. woodworking projects woodworking tools woodworking supplies woodworking basics

Make sure you mark this spacer KEEP! so you don’t accidentally throw it out.
