We got our 2hp Oneida Super Dust Gorilla wired up and are now getting ready to order the ducting. The DC has a 7" port on it, so I was thinking of running 7" for the main and then branching off to 6" wye's. Are the 6" wye branch's overkill? Total run length of the 7" main would be around 20-25 ft straight. I've attached a rough sketch of the layout of equipment. The panel saw has a 2.5" hose hooked up and I want to setup a hood at the bottom to collect the dust that falls to the ground. For the router, I was planning on having one hose to the top of the fence and another below. For the miter saw, I'm not sure what to do. Was thinking to have a 2.5" hose connect to the dust port on the back of the saw. Should I go with 5" or 4" branches for the panel saw and table top router?
Also, any advice on where to purchase the sheetmetal? Home depot/Lowes don't carry a lot of the sizes I need. I was planning on going through Oneida, but there prices seem high. Does anyone know what guage sheetmetal the straight runs are at home depot? It doesn't say anywhere, but they are about 1/3 of the price compared to Oneida? Just wondering if the guage is too thin.
