New Shop Question on Dust collection

[westy33]

Hello,

My first post to this amazing site. I'm designing a 30'x40' metal building to use as a woodworking shop. My question is has anyone put PVC in the floor under the concrete for dust collection to the middle of the shop? I want to place my 50" tablesaw directly in the middle and don't want to hang the duct down as it will be in the way when I work on my truck. Has anyone had experience with this?

Thanks in advance

I have not but I have read where others have. It is a great idea. That and outlets flush to the floor. 240 and 120.

Easy to do before slab pour not so much afterwards.

I read on a similar thread where someone had done this and they loved it and the look was so much cleaner and it certainly made workimg in the space that much easier.

I wouldnt second guess this. Also domt forget to ground your pvc. Bill pentz has a method of alum tape inside pipe but I watched an Australian guy who just installed screws every 3 or 4 feet and wrapped wire around the pipe linking them together amd to ground.

6 inch pvc?

My brother did it in his shop, he's happy he did.

I should have done this but didn't, because I wasn't sure if my saw would remain in one location all the time. Everything is on casters and gets moved around so I opted for a portable DC for now. If you know your bigger machines will be stationary, then definitely put the underfloor ducting in. Use 6" SCH40 sewer pipe (PVC).

For your 90 degree bends use the large dia. "sweeps"

I did exactly what you are speaking of when I built my shop. To the point where I actually made cardboard cut outs with the length and depth of my delta Unisaw to properly place where I wanted my PVC four-inch to come up through the floor. Doing this I also brought up a 110/220 Line beside the saw to power both a saw and have 110 power available there. I also brought up 110 power through a conduit right beside my walk around workbench.

For my dust collection as I have attic trusses above my shop I put my dust collector upstairs and it comes down through the ceiling along the one wall before going into the floor. There are also Branches going off this main trunk to several other tools and of course each tool has its own blast gate. To control my dust collector I use a remote control that controls a 220 outlet in my attic. Made by long ranger.

It sounds like a no brainer. Thanks all for the info and thoughts.

Would you worry about larger pieces or moisture collecting in the piping that would restrict or create a clog?

this was my first thought. i'd want to make sure i had a way to clear it out. I know my small dust deputy/shop vac setup often picks up the thin couple-inch-sliver cutoffs when trimming stuff on the table saw and can get partially plugged. Granted thats a MUCH smaller orifice than 6"

I’ve been a longtime subscriber of Wood magazine. Great rag. Just letting know in the issue I just got today has a pretty decent write up on dust control systems. Might give you some good tips as you plan yours. It’s the March edition.
