Under concrete floor dust collection system (pics)

[Dave Shively]

was asked by fellow Creeker Brad Beam to post pictures of how I constructed
my under-the-floor dust collection system. I have posted it before but maybe it cannot be seen because it has been so long. So here it is again. The system was designed by Oneida Air by sending all my machines and their sizes to them. I have a 3 hp industrial cyclone that sits in a utility
room that has an 8” inlet. The duct work goes from 8” down to 7”, then
to 6” and finally to 5”. All the duct work is under the concrete floor with 11 “duct ports” that come up through the floor. Four of them come up in the middle of the floor for machines like my table saw, WBS, shaper and bandsaw. For these there I also ran conduit and the appropriate size wire for that machine. There is a cover and a hole cut just big enough for the size pipe to come through and a 3/8” hole for a pigtail for electrical. All this is cover with pea fill and then concrete. The system is turned on with a car key size remote. I have had this system for about 4 years now and it has worked flawlessly. Some have said, “What do you do or what if you have a clog below the floor”? I have not yet and I am not worried about it. If it ever happens I run a snake through the line. Oh, the duct pipe is very heavy gauge spiral that is coated with PVC inside and out. Oneida did not supply this but I got it at a local HVAC supplier. I can not remember what I paid for the duct pipe, but as I recall it was not the cheapest. I hope this helps you Brad and any others that this might help.

Man, am I jealous! That is perfect.

[Jim Becker]

Thanks for that again, Dave. I do remember some of that, but the last picture is an excellent view of how things end up in the end!

Ditto what Grant said.

[Norman Pyles]

That's a really nice set up you have there. That took some real planning to pull that off.:cool:

[John Hain]

My jaw is literally wide open now.

Fantastic. Maybe I could...........eh...no.

[John Schreiber]

That is doing the job RIGHT.

[chris del]

That is amazing! What a dream shop.
You are very fortunate.

[alex grams]

that shop looks so clean i would be afraid to make sawdust in there.

All things said though, that is very impressive.

[Bas Pluim]

If Martha Stewart was into woodworking, this is what her shop would look like :-) Absolutely amazing.

[Dave MacArthur]

WOW! What a fantastic shop!

[Mike Canaris]

Those conduits will never clog.... not unless you're trying to suck footballs through them...

Nicely done... well executed... it looks like a joy to work in there.

[Bob Genovesi]

Dave,

You really know how to hurt a guy.....http://img439.imageshack.us/img439/2209/deprimetriste294230fr.gif

Well maybe some day....

Awesome job done right the first time...."The" example for everyone to follow.

[Mike Cutler]

In the words of the old time hot rod crowd. " Very Sano". ( Very clean and professional job)

That's a nice setup Dave. Maybe you have found a sideline talent in planning out DC systems for new construction.
Excellent work.

[Dave Stoler]

I,m as impressed by the view as much as the dream shop!! Awesome!!

[Tim Marks]

Why did you make the "sump" with the removable covers instead of terminating the duct and plugs flush with the floor? Did you do it so you could have a flat floor if you moved the machines to the side?

Nice setup; I like the floor coloring. Now I will wimper and wander downstairs to my one car garage/shop...

[Pat Germain]

Yeah, that's kinda nice. Now, if you'll excuse me, I'll think I'll go set fire to my shop...

Thanks for sharing, Dave. Your example is truly an inspiration.

[Glen Blanchard]

Just beautiful. My wife and I purchased a one acre lot in a suburb north of Dallas this year, and will (in three of four years) build our retirement home there - which will include an (approx) 800 sq ft workshop. I would love to handle my DC system in this manner, but one thing concerns me. I am fearful that, after moving in and making some sawdust, I will realize that I would like to rearrange/relocate some of the stationary tools - or I will purchase a new stationary tool that will necessitate such a relocation. It would seem to me that an "under the foundation" DC system would pose some limitations in such a scenario.

Dave, can you share with me if you planned for such an event, and if you did, how you will handled it?

Wonderful job - it makes me want to begin construction tomorrow !!!!!

[Jim O'Dell]

Man, am I jealous! That is perfect.


Not me, my shop looks tons better than that.......OH NOT THE ONE IN THE PICTURES I'VE POSTED!!! :eek::eek::eek: I'm talking about the one in my dreams! :D:D:D:D
Very nice. Exquisite would be a better word.

I don't think I'd ever put ducts in the floor either, but that's just me. Now maybe if I had my shop all set up in one place, had it just how I liked it with all the machines I ever wanted, then moved, I might. That way I would already know how and where I would want everything. Then I could rebuild the same shop with the duct work in mind. But I'd want a walk out basement under the end where the cyclone would be, and have the cyclone down stairs so I wouldn't have the sharp bend for the inlet pipe......
Hey, How'd I get here at my computer???? Man I was having this really nice dream.....

MerryChristmas everyone! Jim.

[George Bregar]

Very nice. I am building out my new shop in a 24x36 three-car garage, and plan on running under concrete duct work to the TS and jointer. Just going to cut a channel, run the ductwork and electric, and then patch over. These machines should never have to move so having under the floor makes sense and is not too costly.

The rest of the stuff will be handled above floor allowing addition and relocation.

[Steve Clardy]

Mine is under floor and have never regretted it.
I put in a few extra inlets. Glad I did, as I have rearranged machinery.

[John Schreiber]

. . . Just going to cut a channel, run the ductwork and electric, and then patch over . . .
I'd often thought of building with a raised panel floor on 2x8s and having screwed down panels over the ducts. That would give soft footing, access to DC ducting and electrical when needed, and flexibility (but still a pain ) to move machinery.

I've also seen steel plates over channels poured in concrete.

[Alan Schaffter]

My shop is above my 3-car garage. The DC/cyclone is in a utility room off the garage. 6" PVC S&D runs along the ceiling and goes up through the floor to multiple drops in the knee wall and also up through small hatches in the middle of the floor for the TS and jointer. The whole system is easy to reconfigure.

That is nice. My wife and I are building a new house for ourselves (we're builders) and I thought about doing that in my basement shop, but we're on a rocky site and just to get to grade for a fourteen course foundation (block) we had to enlist the help of a demolition hammer. So, there was no way to get the ductwork under the slab without sacrificing basement height. Maybe next time.

BTW, you can see the house in its present stage at page nine of Peercon.com.

[Ken Fitzgerald]

Dave....as I get ready to install my 2.5HP Onieda system and hang the pipe...I'm jealous!

[Cliff Rohrabacher]

way cool~!!!

[Rick Gifford]

That is just super cool. What a nice shop. Like that floor! My eyeballs got big checking those picture. Congrats!

[Joel Ficke]

Incredible!

[Tim Marks]

Is the garage on a hill so you have walk-in access, or did you lug all the macinery upstairs? Nice job on the DC pipes on the floor; those hatches are pretty slick.

[Dave Shively]

Tim,

You are exactly right about the covers. They are there so I have a flat floor just incase I moved a machine. When I built the shop I didn't have my WBS then and the cover was there for obvious reasons.

Dave

[Steven Beam]

I still would like to know the construction products and methods for the sumps.


Thanks Brad Beam

[Cary Swoveland]

Dave,

I did something similar, running a single 6" PVC pipe under my floor. It services my TS, planer and jointer, which are grouped together near the middle of the shop.

One unanticipated problem I had during installation was dealing with the pipe's efforts to float in the wet concrete. I considered filling it with water, to be pumped out later, but decided to instead to pin it down with wooden stakes and twine. Did you have any floatation problems?

I also installed power and hot water radiant heating in the floor.

He has a Winch to raise and lower tools. Here he is loading a 15 inch planer in my truck I bought it last week

[Dick Strauss]

That's an awesome DC setup and a radiant floor heating system to boot. Man am I jealous!!!!!

["Felix Marti"]

Hello Dave.
I have an Oneida overhead system in my current shop; am moving to a new shop (designed for me, by me) and will move my Oneida cyclone to the new location (unless i sell my current property (at 7,800 ft elevation near Our/Telluride Colorado) "as-is".
Everything you describe/discuss makes sense, including conduit for electrical; but one detail with which I am struggling, is the ports (or port boxes) cast in the floor.
Did you find some off-the-shelf options somewhere.
Since I don't often go looking at websites/blogs please respond to: fmarti@ridgwayco.net; and include others in the response if you choose.
Thanks,
Felix

[Bill Space]

Asking for a personal response does not help others who may have similar questions.

AND seeing this is a 12 year old thread...good luck!

But one thing I have come to realize in life is permanent decisions ARE permanent.

I would never bury my dust collector piping in concrete.

Just me I suppose...

not just you. if I were to have the opportunity to build a shop like that, I'd probably engineer it to run the pipes and power under a raised floor

[Jerry Lowetz]

"run the pipes and power under a raised floor"
Working in IT, that was my first thought too, but the concrete will sound insulate the pipes MUCH better than a raised floor.

Is that rebar in the 3rd/2nd to last pic, or a heated floor?? :)

[Steve Clardy]

My main piping has been under concrete since 1997 or so, and I haven't ever regretted it. I would do it again if need be.
