Dust-Free Bandsaw

RATE THIS:



I replaced my bandsaw's wimpy 1-1/2-in. dust-collection port with a shop-made shroud that makes bandsawing virtually dust-free. The secret: My shroud's intake port is much larger (see photo below and exploded view). Another great feature is that the big hose mounts on the back, so it's out of the way. I built this shroud by improving a similar design I'd seen in an old woodworking magazine. My shroud is mounted on a steel plate that I cut to size with my angle grinder (1/4-in.-thick plywood would also work for the mounting plate). I attached this plate to the saw's casting, using the same tapped holes that held the original port. On saws without a port, you'll have to drill and tap a couple holes in the casting. The shroud's angled top allows the table to tilt. I sawed the back plywood face to match the profile of the saw. I left the front face as wide as possible. It actually extends inside the door and is cut to fit around the wheel. I cut a 4-in.-dia. hole in the back face and installed the sheet-metal duct. Then I attached the faces together with a length of 22-gauge galvanized sheet metal. The lip at the bottom helps keep sawdust in the shroud. Once the shroud was mounted, I marked and cut the saw's lower door, so it would close. I was reluctant to alter my saw by cutting the door, but I'm glad I did. This shroud makes bandsawing much cleaner and more enjoyable.

The intake port is about the same size as the hose port, so it doesn't restrict the flow of air to my dust collector.
