Been probably 4 years since I’ve been on here. If you look at my profile I have since moved back home to IL and built my shop. Will update profile with some new pics once done setting up shop.

Looking at placing my machines in dedicated places and running hard ductwork. I have Oneida dust gorilla pro and use 7” flex hose. Flex hose with this big collector works BUT not ideal.

Anyway anyone out there go the cheaper route and use stove/heater vent pipe? Or should I just bite the bullet and use Oneida ductwork.

Any ideas?

Why wouldn’t you use PVC/CPVC DVW pipe? Seems like that would be the cheapest option. If static is a concern you can run bare copper wire inside and ground it. I really don’t know why that wouldn’t work.

Cheapest way would be 6” PVC DWV piping. Reduce at the machines to 4” (or whatever). Your dust collector (I’m assuming it’s the 5hp model) will support the 6” diameter piping without any problems. Dependent, of course, on how long the longest run is, and what machine it services.

If you know exactly where you are going to place your machines (with some possibility for movement), then you might want to bite the bullet and go with steel. It doesn’t sound like you plan on moving, so buy once, cry once. There are other mfg’s for dust piping. I actually have a local place that I could go to, if I ever decide to change over to steel from the 4” PVC/DWV pipe I’m running. 5” for my system would be optimal, but isn’t available in PVC/DWV, only 4” or 6”.

Since I’m spending your money… Also opt for the automatic blast gates. In my shop it’s a PITA at times to open/close gates as I switch from one machine to another. But I work in a cramped basement where I need to constantly move machines around to gain work room.

I just read some article on this… The official ductwork is ideal because of the nice band clamps at each fitting make things easier and don’t restrict airflow. PVC is a good choice because the inside of the fittings are fairly smooth and don’t restrict airflow much. The stove pipe fittings can’t be done so that all the connections ‘go with the flow’ and they cause lower airflow and clogging.
I don’t know where I got this recently.. It might be a stumpy nubs article or video. I hope I’m remembering it all correctly.

I think that PVC/CPVC DVW pipe comes in large sizes, including 8”, not sure about 7”, but 6” for sure. I’d make trunks in large size, smooth walled. You could use 6”, 7” or 8” flexwall (4’ to 8’ at most) for the hookup to the collector to the trunk(s). The drops from the trunk can be smsller sized smooth wall pipe, like 4” or 6” depending, but you can also do shorterdrops in flexwall pipe, as long as you keep to reasonable lengths. The plastc DVC pipe will be less noisy than metal, and you could use longer “sweep” type fittings for T’s, bends or elbows

Thanks everyone, I ordered Norfab quick clamp. Kinda pricey but I think I will like it. Tried dealing with Oneida where I purchased my dust collector but know one would get me a quote. I dealt with 4 different salesman who each apologized for the other salesman but I never received a quote. I called and sent emails to each. I will NEVER purchase anything from them again Just Horrible.

Here is a video that may help you out with the Norfab and making sure you set up your runs so you dont inadvertently starve the collector. The video is based on the Clear Vue cyclone but I think the same tips would apply to the Oneida as well.

Edit: Forgot to mention that is one impressive shop space.

Thank you sansoo22, I built it when I moved here in 2016. It’s 40×80x12. One end is woodworking and the other end is welding/auto work.

Thanks for the update, look forward to pictures, maybe even seeing your working plan or sketch. Looks like you chose well, it’s a neat looking system that I think would be good to work with. That is an impressive space!

I’m surprised your experience was so bad . Mine have always been pretty good w/ Oneida . Can you explain any further ?

Color me very jelly. Your shop has more square footage than my entire house.

If I had large gorgeous shop space like that, I would never leave; except to buy more shop supplies and maybe food. :-)

Enjoy!!!
