Default dust collection for a small shop

I've read many threads on this forum about dust collection, but not all of them (there are so many!). They seem to assume one has a lot of room to put ducts and the dust collection machine itself, etc. I don't have that. I have a larger shop vacuum I use when planing wood. I take the machines outside on the driveway and use them there. I wear a surgical dust mask. I vacuum the dust up as I go. I don't cough after a project, but that doesn't mean I haven't been inhaling wood, I think.

What does the person without lots of space do for decent dust collection? I'm sure I'm not the only one with this issue. Any posts on this forum that deal specifically with this issue?

I do have room for the type of dust collector that mounts on the ceiling that filters the whole garage, but I usually work with the garage open, so I'm not sure this would work well. Besides, the garage isn't sealed so any dust collector would suck in outside air.

Could I mount a small dust collector on the ceiling? For example, mount the Harbor Freight one up high? Not sure where I'd run the hoses. Maybe have a longer one I could hook up as needed. The bag will be an issue, too. Thoughts?

Today is the last day at Harbor Freight for the 25% off coupon for the DC unit. Several people have dismantled them and moved the parts around and up high. You can also roll it outside during use. You don't want the bag inside the shop when it's running, it will leak all kinds of fine and dangerous fine dust into your shop. You might construct a small shed, or a lean to next to your shop with a tube through the wall to attach your hose. Use the Rockler attachments. Don't forget the chip collector, it makes a serious difference.

That's what I found so I got the Wynn 0.5 micron cartridge filter - makes all the difference in the world! I no longer have that fine layer of dust on everything around the DC and the rest of the shop.

I agree about rolling it outside if you have that option (I don't) but otherwise get the Wynn or equivalent filter.

The shop vac will take care of the debris (larger particles). If you are outside with the machine then if you are really concerned that you might still be breathing fine dust, and you might be getting some, then I would take a pedestal fan and position it at your side blowing across the dust source at an angle. That's the cheap solution.

You don't want the HF unit inside your shop without adding the filter David mentions which is about an extra $100. Putting it outside is not always an option and you may not want the side of your house caked with fine dust or your neighbor calling and complaining about it either. The ceiling unit takes time to clear the air. It won't prevent you from inhaling a bunch of dust while you are working. You can wall mount some DCs but they still take up some room and it's common to see piping running across the ceiling, especially in commercial situations where you need to do that to eliminate tripping hazards.

Someone I consider a master woodworker once told me that a master woodworker is not someone who never makes mistakes. He is someone who is able to cover them up so that no one can tell.

install your unit outside the shop in a ''closet''..
vent the closet back into the shop to preserve your HVAC...

before you jump on HF unit... read what has been said about it here..

My experience is the opposite. I run mine in my garage, and don't see any fine dust escaping.

I do have a dust collector similar to the Grizzly GZ1028Z2. Sorry, I forgot tot mention that. I took it to work to store it (I don't have any space) and I forgot I had it. It runs on 220, which I don't currently have a plug for, which I could add fairly easily. I suppose I could keep it out of the garage and wheel it in to use. With the addition of the Wynn filter it would collect all the dust and not spread it around the yard, the driveway and my lungs.

I use a fan sometimes to blow the dust away, but with the garage open, any breeze blows the dust everywhere. The mask helps, but it fogs up my glasses.

I can't build anything fancy outside my house; the HOA (and one neighbor in particular) will not like that. But, I might be able to put the dust collector in some sort of small shed as long as it is hidden from view. I'd have to run a power cord to it along with any dust collection hoses. It would be a 30' run, I think. Probably too much for the dust collector.

I just don't have room in my garage for more stuff: I have a metal lathe, table saw, metal mill, 2 cars (one is the wife's and one is a classic car, so they cannot live outside at all), a workbench and a toolbox. These take up all the available floor space and still leave room to walk around. I have everything else in cupboards and cabinets mounted on the walls and ceiling. I get out any other machines I need to use and mount them on a portable work table.

Just to clarify: the Wynn filter you're referring to is the big one that takes the place of one of the canvas bags, right?

You don't mention what tools you are using, and this matters for your dust collection. If you are using tools with a 4" or larger dust port, then you will need a DC like the Grizzly you already have. If they are smaller portable tools then you have other options. Either way, you can get creative to save space. I have a narrow shop and did not want a shop vac taking up floor space, or a dust collector that was constantly in the way. To solve these issues I installed a central vacuum that handles all of my smaller tools like my miter saw, router table, oscillating sander, and shop cleanup etc... This vacuum has a heppa filter, small dust deputy, uses 2" ducting and blast gates at different tools. With the dust deputy I haven't had to change the filter in over 2yrs. I also use this for a my hand power tools. For the larger tools I modified my Harbor Freight dust collector so that it hangs in a corner with a dust deputy cyclone, 5" ducts run high on the walls and ceiling and I exhaust it outside to eliminate the filer. With the cyclone there is no visible dust exhausted outside, the one downside is that most of the noise is also exhausted outside which might cause problems with your HOA. My neighbors are mostly deer and other critters so they don't complain. The point is with some creative thought you can over come your space constrictions and have decent dust collection.

The central vac takes up less than 18", (there are smaller units available) with the dust deputy a little more space is needed. The DC takes up about 30" and all of that is for the trash can. Again a smaller collection bin could be used.
