Tip 4: Clamp on a long fence for long boards Keeping a long, heavy board or a full sheet of plywood tight against a short fence is a challenge, especially when you work alone. It's all too easy for the wood to wander away from the fence, ruining the cut or causing the blade to bind and leave burn marks along the edge. To avoid these problems, clamp a long level or a long, straight board to the fence. The longer the fence, the easer it is to keep the wood firmly against it.
