This is a project I have been wanted to do for a while but since I got a smaller hose that attaches to my ROS I kinda put it on the back burner. I decided to go ahead and do it. I used pine and some pegboard. I also used some thin paneling for the inside tapered bottoms. I tapered it all to the side hoping it will all go to the suction hole in side. Initially I plan to use it with my shop vac. I haven't used it yet but it sucked pretty good just throwing some dust up on it.
