Plywood panels can be tricky to crosscut. Even when using a crosscut sled, it’s hard to keep enough pressure on the piece and make an accurate cut at the same time. The material wants to lift away from the blade. A nice solution only requires a couple of roller stands and a 2x4. The two stands along with the 2x4 are adjusted to the height of your sled. The weight of the panel clamped to the 2x4 allows the whole assembly to glide across the rollers smoothly.
