these are examples.. these method of hook up seems to work the best...
BTDT w/ the vac.. just too much BS to put up w/...
so hook the 2.5 port to the the Wye.... don't use a T, use a Wye..

stick one these under the saw and hook that to the Wye..

hook the Wye to the at least a 600CFM, 1.5HP DC w/ 2 micron or finer filtration...
Done!!!
