So I have my CV1800 installed 90% of the way with a few ports capped due to not being ready quite yet. I have a drop with a wye for two accesses, one for the drill press and one for the lathe (Shopsmith) which will basically be hoods on stands. Then I have one more drop with a wye that will service a miter station with hood once built and an additional connection for either the SuperMax 19-38 or the 13" planner depending on need. I do have one 6" drop that serves both now as needed with a 6" to 4" adapter. The adapter I have is not very good I'm afraid as it should probably be more like a cone with 6" tapering down to 4" but instead is like a 6" can with a 4" collar cut into it if you can imagine that. At this point I have the 6" PVC taped together using 3" wide aluminium tape which is fine for the horizontal parts but less than adequate for the drops (vertical). The PVC is supported by using a mesh nylon 2" wide strapping material which is secured to the ceiling joists thus eliminating vibration. It's the same method used to hang metal HVAC ducting in crawl spaces.
So at this point I'm thinking I need to either seal the vertical pieces with caulk or drive a screw or two into the PVC. I noticed a previous past post that mentioned using self tapping sheet metal screws and really think this isn't the best choice. I don't think, and could easily be wrong, but I would suggest not penetrating the inner wall of the PVC. Instead I would think drilling a pilot hole and using a screw that will go through the outer pipe/connector and then into but not penetrating the inner wall of the connected piece might be better. Maybe this is overthinking this but by not penetrating the inner wall doesn't disturb the air flow at all.
Ideas, suggestions? KNow of a better way to secure the vertical drops?
Thanks,
Steve
