Dust Collection and Power Under Floor?
      #6026414 - 08/11/12 04:31 PM

I am retiring next summer and am in the process of designing my dream shop. I will have a 48" crawl space under the shop, 36 x 52 with a 10' ceiling.

My thoughts are to run the dust collector and power for the floor and in some kind of opening hatch to connect the DC and power. I don't like having the machine power cords and DC connections to trip over. Mainly I will have the table saw, jointer, and planer towards the center of the shop. The other machines around the wall space. Any thoughts or ideas ? Thanks Mark

Is it going to be a wood floor or cement?

I think that's best way to go, Mark!

The fact that you'll have a crawl space allows you all the flexibility you'll need in locating tools.

The floor will be engineered floor joist 16" oc with 3/4" plywood. I am thinking about building / buying, and putting a box between joist under the floor to hold the DC and 220 vac plug. I want to be able to move the machines in case I have to work on a vehicle.

Working on the same design right now .. We are selling this house and going to build a new one with a shop off the garage..

I was planning 2x10 SPF 12" OC with about 9 foot spans.

Think of running compressed air lines under the floor as well ..

Also consider a staircase down to the crawl, its a good place to store stuff .. Lots of room.. If you have a nice wide stair case ( 48" ) down to the crawl, you will probably use the space more ..

I would be careful with bringing ( vehicles ) over a 3/4" floor.

I thought about the weight of my diesel 1 ton truck. I was planning on running a beam under the floor where the tires would ride for extra support. I think the engineered joist would support the truck if supported well. Maybe blocking between the joists as well.

I would ask the truss manufacturer if it would be allowed, and if so, how.

On my I-joist house, the floor deck is 1 1/8" plywood. Much nicer than 3/4" decking.

If your going 4 feet, how much extra to go 9 feet and make a basement?

I had a long conversation with Bill Pentz (the guy that designed the cyclone that several vendors use including and mainly the clear-vue) a few weeks back and his recommendation is to always put the DC outside of the shop, in a small room, if you have that ability. It's always the super fine dust you cannot capture in the filters or bags. Putting it outside would eliminate that issue... Sounds like you have the ability to do just that if you are designing from the ground up. He also recommends using 6" pipe as close to the tool as you can get it.

here is his informative website for any that have not seen it:
