Allan, depending on how often you think you will use a tall fence BJ's solution is an excellent one. If you think you will use a tall fence for a lot of projects you can build an extra fence with two pieces of MDF or plywood set at 90° and support it with some gussets. Using your regular fence as a guide cut a small chamfer on the bottom of the face for dust to escape through. You will see this feature on your poly fence. This type of fence is used for some projects on the Router Workshop show.
