After April’s discussion I bought a Delta 50-760 and installed in my shop. You need a picture but I’ll try and describe it. The ductwork is connected to the collector thru a 5″ hose that drops 27′ from the duct to the collector. the hose connects thru a 90 deg elbow connected to 39″ of 5″ duct to a ‘T’. The left side of the T is attached to 33″ of 5″ duct, a 90 deg elbow and aan 8′ length of 5″ hose. The hose here is attached to a 5″ wastegate on the base of my table saw.
The right side of the T is attached in sequence to 7′ of duct, a 90 deg elbow, 13′ of duct, a 90 deg elbow and 7′ of duct into a wooden plenum chamber. The chamber has three 2″ blastgates for vacuum hose.
The amount of air movement at any pick up point is mediocre. I swear my shop vac could lift more stuff.
Local opinion is that I need to replace the T with a Y. An article in another magazine written by S Nagyszalanczy, has a proposed layout utilizing a T.
I have used metal tape on all seams, and around all joints and I cannot detect any system leaks all though I am sure some exist.
What should I do? Thanks

Warren,
The small dust collector you have is meant to be hooked directly to one machine at a time with a short piece of 5 inch hose, that's why the Delta and similar machines are on wheels, so they can be moved from machine to machine.
The duct system you have would need a much more powerful collector, something in the range of 5 to 7 hp as an educated guess.
