« Part 1: The 10 minute tour of my workshop Part 2 of Workshop Tour series Part 3: The attic and office »

I think that I have kind of a unique dust collection system so I did a separate video on just it.

What makes it different from most is that I built it under the concrete slab. I was able to do this because I designed and built the shop from the ground up for just being a wood shop. I wanted to do this for a couple of reasons. the first and foremost is not to have a bunch of pipes all over the walls and across the floor.

I put pipes under the concrete going across the floor from left to right in straight runs. Just an elbow at each end, The reason is just in case something gets stuck, it’s easy to clear out. If it’s too long to get around the elbow I can just reach in and take it out. I can’t really see anything getting stuck in the middle of a straight run so if it does get plugged with anything it will be at either the beginning or end at the elbows. If by chance something did get stuck in the middle I could run an electricians fish tape through the jam and out the other end, and then attach something and pull it back bringing back the jammed up stuff.

I ran pipes along the bottom of the walls, front to back so that I could make all the attachment points I needed. They are a few inches off the floor making it easy to clean around them.

I have two outlets pop up in the center of the floor. One for the tablesaw and the other behind my workbench. The one behind the workbench is not being used yet, but I plan on putting a downdraft sanding station there. I also ran electrical wires there for power.

It’s real nice not having either pipes or wires across the floor of dropped down from the ceiling.

Good planning, Gary. When I built my shop 30 years ago, I didn’t know what a dust collector wasw. The concrete floor was a last minute decision. I am planning on piping mine in the ceiling and blowing the chips outside.

I don’t know how long you have been using your system or how much but, having unloaded rock dust and other materials from tanker trucks for many years, one thing you learned quick was to try and never have a flat run. Gravity may acutally be working against you instead of helping. The material needs to stay airated to move thru the pipes and when you have flat runs gravity pushs it to the bottom of the pipe instead of it staying mixed in the air and moving. The only thing that may save you is the volume of material moving thru the pipes. You should probably try to make sure that you never let to much go thru at one time or to let bigger dust particles go thru. I hope none of this happens but if it does, then this will probably be the reason you have trouble.

Built2Last – That’s interesting. I have been using for over three years now without any problem. I even use a flexible hose to pick up big piles of sawdust giving it a worst case scenario. We’re talking fine dust, regular sawdust, chunks of wood, paper… all at the same time. Works like a charm.

I think that with rock dust it would settle and compact. It has a lot more weight to it.

Sawdust isn’t really dust in that sense. It’s a lot more coarse and doesn’t really compact. There is a component of real fine dust but I imagine the coarse sawdust agitates it enough to keep it moving.

This is a nice system that you have installed in your shop. It appears to be well planned and engineered and putting runs under the floor was a good idea. Hiding the runs like this along with putting the other trunk lines along the wall behnid the tools is a good way to conceal the runs.

this really sucks (LOL) !

in my last shop ,
i had everything in the ( wooden ) floor ,
every 10’ i had a ” service station ” .
i made boxes in the floor joists ,
that had 6” vacuum ,
2 separate duplex 220 v outlets ,
2 separate duplex 110 v outlets ,
and an air line .
the boxes had a removable top flush with floor ,
that could be custom cut to allow any cords or tubes to be brought up
to the tools or work stations .
the plugs were all in the box sides ,
so no dust would get in them .
i’m in the process of building a 30’x40’ shop now ,
and will do that again in it too .

thanks for your tour .

Gary,
Nice shop & DC video Eastwood has nothing on you.
I’m putting together my shop and this will come in handy to reference from.
Did you ground your DC system before you poured the concrete?

Appreciate the tour, your info is very good. Thanks. I always figures for a setup like you have a guy would need a 3 hp cyclone. Once again you have given the info to prove that the top of the line stuff is not necassary and probably overkill. Well thought out system thanks

degoose – That was very observant about the “Japanese Safety Boots”. They were only visible for a split second.
BUT, I was just doing a video not working. :-)
I always throw those on just to run out to check on things.

Gary,

Great shop! I’m working on doing my basement and currently planning the dust collection system. Do the PVC pipes cause any problems regarding static electricity? I’ve read that the pipes have to be grounded somehow or one might have an explosion. Did you do anything special?

Bruce – Some will say that you need to ground it no matter what the evidence.

If you were going to use a 3HP or greater motor, I would say yes also. Anything less that that I wouldn’t worry about it.
I don’t. If it will give you peace of mind go ahead and ground it.

Do some google searches and you will find that you really don’t need to if you’re under 3HP.

Gary, thank you.

I’m busy planning my extraction and never thought of going under. Doh!

Crazy thing is the new shop has a 24”crawl space under.

I was looking at square to hide the ducting, now I can rethink my plan.
