   Speaking of dust collector plumbing (and not trying to steel this thread, but also not wanting to start a similar thread) anyone know if I would be better off to keep the 5" duct that the collector as until I start splitting off or should I just step it down to 4" And if I should keep the 5" where can I get 5" duct work?

   Keep the 5" and reduce close to the machine hookup.  The Oneida-Air web site explains this in buying ductwork for 2hp and under systems, I do not have the link handy.

   Edit: I found the link.

   Penn State industries sells ductwork and other fittings in either 20 g (thick, industrial type) or 26 g, thinner, comparable to the HVAC ducts you can get at Home Depot.  Most main ducts are 6 inches, narrowing to 4 inches for the side branches

   My problem is (I think I will have to check it when I get back to the shop) that I have a 5" duct coming out of the delta dust collector. It currently has a funny "Y" connection on it that goes to two 4" units and I can turn the thing upside down (well sort of) to collect from the top vs the bottom but I don't remember the number of the unit.  Anyway I think this thing has a 5" intake and I am having issues finding any 5" stuff. I figure I am about a month or so from starting to really put the shop together and this is one of the first issues I will face when I start that. Currently this tools are just kind of hap hazard arrangement in the garage space as I build the house.

   Penn state does have 5 inch duct.  Their printed catalogue has some diagrams suggesting basic dust collector design.  Grizzly and others also sell a small paperback on dust collection system layout.  Try to minimize any right angle turns, keep the diameter as large as possible, the runs as short and direct as possible, and the tubing as smooth as possible to minimize airflow resistance.  Read about electrostatic charge and grounding, if you use any plastic or PVC pipe. Not and issue with metal pipe.

   Good luck,

   I bought all my duct bits from an industrial HVAC supplier. If I recall, spiral, etc., are ablout 1/2 price vs. the dust collector guys and its identially the same stuff, same gage material, etc..

   I figure the dust collector folk buy from the same manufacturers.
