DIY autostart dust separating vacuum system for power tools and general cleaning around your small workshop or garage. I also ran a dedicated outlet on the wall for the saw from the sensed circuit across the room for the other tools on the vacuum system. Way way way better than the paper filter that needs a severe beating every 10 minutes. It just gets more irritating until I finally dump it, and beat the filter or replace the bag. This contraption sits inline with the shop vac removes most of the sawdust and wood chips before they reach the vacuum’s tub or filter. Then he drilled a hole for the vacuum hose in the bottom and made the frame out of lauan. Thoughs of you who have or have seen the Rainbow vacuum knows that it uses water as the filter.
PS becuase you said home made i lept to the conclusion it was for wood, apologies if its for grinding dust and such. Update: The Shop N Garage forum is defunct, so the broken links have been removed. This allows dust whipping around the inside of the separator to drop into the bucket and not get picked back up. I started by making a slightly smaller circle than the last one. Its fine grain does not allow the dust to cling and clog it up, so the dust can fall down. But I’m not saying put the filters on larger dust collectors in front of the blowers, but put something there.
The chamber is intentionally shaped to circulate the incoming dust in a cyclone, allowing the heavy sawdust and other chunks to fall into a bucket. An older, used gas powered leaf-blower mounted into the top of the barrel sucks the air from the barrel – creating the vacuum. You want to shake it out pretty well first because when you run it with no filter all the dirt goes through the fan. It makes a big difference; the bag has far more area than the little circular filter and captures dust more effectively.
The vacuum can be switched on and off from outside the box, it will work with tool-activated vacuums, and I can now sand at will without creating either air or noise pollution. Vacuum up the area that was going to be cleaned and make sure the vacuum is working to ensure the pantyhose filter has been properly installed. The Cyclone separates and collect the dirt and debris before it gets to the vacuum filter. After less use than you’d think, I had an inch or two of sawdust that made it into the bucket rather than my expensive shop vac filter bag or my lungs. The center hole in the separator connects to the shop vac, the elbow outer hole connects to the hose.
His work has been published on Wired Design, Bob Vila, DIY Network, The Family Handyman and Popular Mechanics and he has been featured on the Martha Stewart radio show and as a speaker at the ALT Design Summit, K/BIS and the National Hardware Show. When I am sucking up the leaves the vacuum will pick up loose stones and the like but it will not suck up the underlying dirt with any ease.
In his post, Goodfellow also describes how to use the separator as a fine dust trap. By using polycarbonate for the side walls, you can see how well the collector is working without lifting the lid. I also added a wall switch directly across the Aprilaire current sensor to aid in shop cleanup. No sawdust getting to your filter means it says cleaner longer, and allows for more suction.
I can work in my shop with my shop-vac dust collection and nearly match what I’ve measured in shops with BIG cyclones and very intelligent dust fittings. I have an old Rainbow brand dry/wet vacuum that my mom got at a yard sale, similar to this model My family grew up with this kind of vacuum at home, and it was useful not only for typical carpet sweeping, but also for cleaning up wet messes. I planned to have the separator sit on top of my shop vac, so I can roll them both around.
Back in the day when I was a broke student and couldn’t afford luxuries like new vacuum cleaner bags I just emptied the old one into the rubbish and reused it. It’s a bit fiddly and you’ll want to wash your hands thoroughly afterwards but it’s viable. I cleaned the inside of the shop vac and blew out the filter and then hooked it up to a dust deputy and vacumed up a 5 gallon bucket of fine sanding dust.
The second DIY option Deutsch put us on to is this sub-$20 solution , this one designed to be used under a blast cabinet, but still applicable to collecting dust from power tools. I use one of these in my shop (backed up by an old Penn State collector that I picked up for not much). Hooking up a shop vac to suck up dust coming off a wood-cutting machine works for.

I’d like to add my 2cents of engineering by saying that overdoing the muffler will induce a counter pressure on the propeller thus creating stress. I also blocked up the shop vac to prevent it from rolling off the scaffold during use. So all I am in need of is a completion of the circut to flip the leg and turn on the outlet for the shop vac. Most of us woodworkers would rather spend our time making sawdust then cleaning out shop vac filters.
These days, most bench-top saws and planers have dust ports, and they make a huge difference in controlling dust, even with a shop vacuum. To mate different ports and hoses, you can buy standard adapters at your local home store or cut down a universal adapter to fit — but you should still plan on needing duct tape, because many toolmakers haven’t yet standardized their dust fittings.
I’m thinking of taking down a wall to open up the kitchen and I’m planning to use that plastic so no dust gets into the next room. Note: You’ll find that dust collection on miter saws isn’t as effective as on other tools, but this will definitely help. It could be assumed that the larger the space the worse the problem as once the dust gets free there is an very large amount of air to scrub to get the dust levels down to an acceptable level unlike a small space that the air can be scrubbed fairly rapidly.
Interestingly enough, it incorporates a water trap in the bottom to capture the icky blast media, and features an interior baffle to prevent any splashing water from making its way into the shop vac. It is a very versatile shop vac, a dry/wet vacuum which can be used as a blower as well. It collects the heavy chips first allowing the cyclone cannister to not load up so fast. If you’re lucky, you can plug the vacuum hose directly into the dust port of your tool.
Or three, plug your tool and vacuum into a special power box that activates the vacuum when the tool is turned on. You know what…..If someone would design a shop-vac using the principles in this post, you would never need a filter in your shop-vac. Although this did remove the rushing noise of the vac from the house, the longer hose created oscillation that caused a deafening siren-like howl at the business end. When I take the shop vac out, i just pull the pipe out of the separator and turn it to the side, then lift the bucket. Not exactly sure on yours but my vac says to remove the filter when sucking up water.
