Thanks for the input, my idea worked great!! I am running 45’ of 8” , 3/ 90s, 1/8”X6”X6” combo, 1/8”X6”X6” combo, 30’ of 6” , 2/90s 1/^”combo., 3/6”X4” reducers, 3’ of 4” ABS 4/1/4 bends and 20’ 4” flex with 5’ 0f 2” flex for a vacuum line with a total rise of 20’. My vacuum line works better than a new shop vac. With my drum-sander & planner line open, I need to make some blast gates.

After seeing the efficacy rating of spiral, the size available in PVC, ABS, cost of laser welded stainless what I have works well so far and is (I used almost no screws through my pipe) rated the same as laser welded pipe
