Here my dust collection set up. Used 2" schedule 40 pvc. My hose on vac is 2 1/2 " and fits snugly inside the 2" tee. Also used an end cap and drilled 3/4 in hole and fit nicely over wheel exhaust port. Then used 4" to 2" reducer and a short piece of pipe to fab a leg support, will contour to match the tee and glue it on. Very happy with my XO-2 and 95/75 spinner.
