Miter saws are a great convenience, but they spread sawdust like a sprinkler spreads water. The new Downdrafter shroud from Rousseau, $200, combined with a dust collector, acts like a parachute behind the saw and grabs almost every bit of dust. You may cringe at the price, but some good engineering is at work here. The shroud is mounted on a sliding track and a pivot so, no matter what angle the saw is set at, you can position the shroud in the high sawdust traffic area. The dust collector creates a down draft through the port in the bottom of the shroud and dust disappears. Without the slide and pivot, it would take a shroud the size of a garage to capture dust at every angle a miter saw can cut.The shroud is deep enough to accommodate sliding saws and large enough to surround even the biggest miter saws. A shop vacuum provides some dust collection, but this unit works best when used with a dust collector.
