My Dust Cobra has a 2 1/4" hose which I use to vacuum the shop and connect to machines as I use them. It came with a wand and a few attachments. Having spent years designing industrial dust collection, I am not happy with the dust pickups and other hose end devices. They are designed by hacks who don't test their product. So I made a couple, one from PVC pipe and one from stiff paper and wood. The PVC attachment for vacuuming the floor is better than the one provided but there is room to improve. The paper and wood pickup works great on the bench top for sanding and routing but is just a mockup. It should be more durable. The traditional plastic used is the right stuff but I don't know how to work with it. Any suggestions?
