Dust Collection Requirements & Recomendations?
Question:I built a 16' x 16' shop in my backyard. I intend to use a table saw, radial arm saw, 6 1/2" jointer/planer, router table, 9" disk/6"belt combination sander, scroll saw, and a drill press(with mortising attatchment). I have never established a dust collection system before, and have no clue as to flow rate calculations, or pipe size.
I work in a sheet metal shop, can I use steel duct instead of pipe? Yes, I can form Pittsburgh seams, and alum. tape will seal joints.
My tools will be located in an "L" shape along two walls, with the table saw in the middle of the shop, and the radial arm saw off center.
I know: Not much out feed in a 16' shop, but everything out feeds thru thoughtfully placed windows, and 6'0" double door .
Answers:
Yes you can use the steel duct to do this, but you will need to make sure that your dust collector motor can create enough suction to pull the sawdust through the ductwork. You do not want it to collect in the ductwork itself, because that could lead to clogging, or worse fire. Use blast gates at every tool. Only open the gate at the tool you are using. Be sure to dd a cyclone collector to make the unit more efficient.
Look at this web page, it will help you accomplish your plan.

Grizzly tools has good deals on dust collectors thing to remember if your the only worker in your shop than you only need enough suction to run one tool at a time. and like the other guy said you put shutoff gates at each tool and just open the one your using.
You can use steel duct to create the network of pipes to your collection unit. Refer to this website for an excellent article on creating a dust collection system and all the associated routing, pipe size, CFM info...etc.
