I bought one of those Delta 50-720 DCs at Lowes back when they were on clearance for $99, and knowing it was a 1-tool-at-a-time kinda DC (650 CFM, 4in port), I'd been dragging it (and my attached trashcan separator) from tool to tool. I thought using ducting might cause an unacceptable loss of CFM over the distance I wanted to run in my small garage shop, so didn't give it much thought until I finally got tired of the endless dragging.
So I parked the DC and chip separator in one corner, then bought some of the 4in polyethylene drainage pipe, some fittings, and hung it on the walls, about half way up - hoping to minimize the amount of CFM reduction I might create by hanging on the ceiling - and I didn't have room on the floor.
I hung about ~24 li ft, half on one wall nearest the DC, and half on the adjacent, only 1 elbow fitting, to form an L. I have a door in the way near that elbow, so decided to make a connector hose to couple the two stretches when I need to use tools on the adjacent wall. Because the DC is only 650 CFM max, I only trust it for one tool at a time - so I built "capgates" for the wye branches instead of using blastgates - in part to save $, but primarily because I plan to move my hose from tool to tool as a reminder of the one-tool-at-a-time rule; also, I have to move tools away from the walls to operate, and I won't have to worry about opening and closing blastgates.
My table saw, planer, jointer and router connect on the segment nearest the DC, and bandsaw, radial arm saw, and various stationary sanders run on the adjacent segment. To test the adequacy of CFM at the end of the 24 ft, I ran my RAS there (I have a DC box on it with a wye to a hose pulling from the blade housing) - and the pull seemed undiminished; all dust was effectively collected.
Some pictures of setup follow. Thanks for looking.
