If you are involved in woodworking by now you know that every woodworking workshop no matter how small it is needs a dust collector. For the table saw, I connected a 4″ flexible hose with hose clamps to a blast gate on one of the wyes. I retro-fitted my Sears Craftsman 2HP Dust Collector with a teflon-coated sauté pan I picked up at the local dollar store for, of course, $1. I removed the handle and will save it for some future jig creation. A single dust collector tugs the wood fragments through an impeller and stores them in a collection bin or bag. Using the table saw was the real test as I’d grown accustomed to minimal sawdust. Using a shop vacuum for dust series; have the important gear for this diy mission covered up earlier than you startyou’ll.
No matter how maintenance-friendly a collector may be, the less service needed, the better – especially in hazardous dust applications. Due to inertia, the larger dust particles will continue on in a straight path, hit the droplets, and become encapsulated. A cyclone separator is an apparatus for the separation, by centrifugal means, of fine particles suspended in air or gas. The top of the separator connects to the vacuum or blower and provides a path for air to leave.
I can tell you what I have at home, just a simple one car garage shop that is 8-1/2′ X 22′. They are also fixed units that are more powerful than the common dust collecting machine. Since cyclone dust collectors provide two-stage collection they offer an effective way of separating larger chip from the dust. The DIY dust collection system shown in the video above is powered by a wet/dry shop vac and uses a Dust Deputy Cyclone to collect dust into a standard 18L shop bucket. This would be easily able to cause an explosion if the right amount of dust was floating in the air at the time.
There HAVE been explosions and fires caused by shops running pvc for dust collection and not putting the grounded copper wire in there. You also want to ensure you take advantage of any opportunities to increase the value of your dust collector through saving on heating or cooling costs, or by improving its reliability with better monitoring and maintenance. Secondly, if you are applying smooth finishes with wood, the dust in the air will always interfere and give you a finished product with many imperfections. I slip the PVC over the small end, and then the bell slips over the dust port on the tool.
To test my cyclone dust collector, I vacuumed a small amount of saw dust off the floor and they were all collected in the bucket. Current standards suggest that 85-86dB is the threshold at which hearing protection becomes necessary to avoid long term hearing damage and since the dust collector is only used when another machine is used, the dB levels will require you to use of some form of hearing protection.
Length of 1-1/4 in. hose for hand power tools and a remote control for the vacuum, and you can work virtually dust-free from anywhere in the shop. Even if a collector has rugged construction and a properly sized explosion vent, you still need to protect the ductwork that serves the dust collector. Also, a separator is used so that the after filter does not receive 100% of the dust-laden air. This means that I’ll have to make the cone part of the cyclone from two pieces of sheet metal, what a pain! The fact is, the two tools it is connected to have very effective passive dust collection and really don’t need this large unit.
And since I’d LIKE to re-circulate the air back into the shop instead of sending it outside in winter this is looking like a pretty trick setup. As you might expect, two-stage dust collectors also carry a higher price tag and have a larger footprint. Previous shop had a 5hp in a separate insulated room with a muffler, and you could easily talk with it on. Next shop will locate one outside with a sound enclosure.
That’s not possible for me so I have to be content with storing the dust collector in an out-of-the-way location. Each machine in your shop will require a certain volume of air to clear the debris it generates and you should ensure that the collector you purchase can accommodate the machine with the greatest CFM requirement (refer to the accompanying chart for the CFM requirements of some common shop machines). Simply hang it from the ceiling and turn it on, and it will clear the room of those fine dust particles.
Keep in mind that running the collector with air dumping outside will increase the demand on your make-up air system. You have to make sure that the machine is well illuminated, especially as a collection table or bench. Cyclone collectors are used when coarser dust is generated, as in woodworking, metal grinding, or machining. The spark can come from turning on or off any electric switch or motor, or the gas hot water heater in the corner of your basement shop. Also, plastic pipe elbows have a very short radius and plastic tee fittings are improper for dust removal. You can capture most nuisance dust with a standard shop vacuum and a few accessories.
Next, it is important you lay-out a system that assures your dust collector and shop tools provide supreme effectiveness for your requirements. A dust/chip collector does several good things; it is an additional filtration level for the shop which is always a good thing, it can prolong the motor life of your Shop Vac, and it saves you from having to buy replacement Shop Vac filters or bags. Important parameters in specifying dust collectors include airflow the velocity of the air stream created by the vacuum producer; system power, the power of the system motor, usually specified in horsepower; storage capacity for dust and particles, and minimum particle size filtered by the unit.
Our equipment solves dust challenges for a wide range of industries and applications: blasting, chemical processing, fibreglass and FRP, food processing, laser and plasma cutting, mining, paper scrap, pharmaceutical, rubber grinding, seed processing, solar panel fabrication, thermal/flame spray, welding, woodworking, and many more. Any appliance repair shop or city dump can produce good drier blowers to serve the purpose well.
If working correctly, the filter will absorb all the dust and dirt, promoting better air flow for the workspace. Understanding key features of your dust collector and your factory’s needs will ultimately save money in the long run because of the lack of repairs or additional accessories in the future. Most shop vacs will come with one of these, but since this is now going to become part of your dust collection box you may want to by an extra. Using a big dust collector is overkill for portable power tools like random-orbit sanders.
Then you can have an air filter which is mounted on the ceiling to purify the shops air (the dust must first pass from your face before it reaches them, so these are good for after work), and finally you have the dust extractor systems which can be complex or simple (if you can afford one they are very good up to a point). Some tools provide adequate dust collection ports, while others (most) don’t and you will need to devise your own enhancements.

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. As I will probably end up with a right-angle run with the dust collector at the right angle, one on each arm should suffice.
