I'm in the final phases of planning my dust collection setup. I'm going to be running 6" from my Harvey Gyro air along the ceiling then down into the each drop. My problem is that all of my tools have 4" dust ports. I plan to run the last few feet from 6" PVC to the port with 4" flex hose. Can someone point me to some fittings that'll work? I've been looking around but I figured I'd ask here and get some recommendations based on experience.
Thanks!
