I cannot seem to find the answer I am looking for. I am in the "design on paper phase" of setting up dust collection in my shop. I am looking to buy the Harbor Freight 2hp with the canister upgrade by Wynn that many here have. I originally was going to have a bit more elaborate runs using 4" PVC with waste gates and using proper wyes and elbows, but am reading more and more that anything over 10' from the dust collector and you are seriously compromised in collection. Anyone with long runs with this set-up? I am just looking for opinions on effectiveness of suction, not about proper grounding and such (don't want to start that debate, thats a different thread. haha) Thanks, you guys have been very helpful with everything!
