I have a Delta 1 1/2 hp 50-760 with an Oneida Super Dust Deputy Cyclone and 5" metal pipe. There is a 5" Y fitting on the cyclone with one line going directly to my table saw about 3 feet away with a 5" T that splits to a 4" line for the saw port and a 2 1/2" line to my overarm blade guard (each with it's own blast gate). Today I switched from using the table saw to using the router table (about 12 feet from the dust collector on the other side of the Y) and realized I forgot to close the blast gate for the overarm blade guard. When I went back to close it I noticed the suction sounded louder than it normally did so I figured I hadn't opened the router table blast gate yet however when I went back to the router table the gate was in fact open already. After a little experimenting I found something interesting...there is more suction at the 2 1/2" line on the blade guard when I open it along with any other 4" blast gate down the line than there is when I open it along with the saw cabinet 4" blast gate that is fed off of the same 5" branch. :confused1: Any ideas as to what may be going on here?
