IMPORTANT: In the video I show an image of a workshop with an excessively long length of flex hose. I found the image on Google and thought it was a humorous example of a big piece of hose. I neglected to provide context for the image. The gentleman in the photo was attaching that hose to a much more powerful system than is found in most small workshops. He could afford to lose some airflow from the long flex hose, and it works well for him. By not providing that context I made it appear that HE was making a mistake rather than my intended point, which is that most OTHER folks should not do that with their single-stage systems. I am sorry I didn't make that clear, which is why I have removed the image from the video thumbnail and I am pinning this comment to the top so everyone can see it.
What was the name of the science website you mentioned at the end? I couldn't quite hear it.

@@StumpyNubs Thanks! I'm putting together a small shop with dust collection next week so very timely episode.
Code is only for minor products. Not the for real deal. Was hoping to get a CV1800 :(
I just tried it. It took $88 off.
The most-effective dust collector I have is my NordicTrack.
I have a treadmill that makes an excellent coat rack.
Undoubtedly the best comment ever.
😂😂😂 You win the internet today! 👍🏼
That is very funny!
Haha, brilliant!
I always turn to your videos to sanity check anything else I watch. No b/s, no over-the-top distracting behaviour, even your promo material is handled professionally. Thank you for being so much help to a budding woodworker.
You are a natural narrator! I didn't notice a single "uh" or "um" and your flow of information was smooth as a planed plank of pine, not to mention mighty handy to have in my brain pan! Well done and I've subscribed and punched the like button too!
I agree. These videos are well articulated, with intelligent and insightful comments/ideas. As I said before, my goal is to watch them all.
Nice tip on the fire hazards of sweeping up nails hitting the impeller. Thank you for taking the time to make this video, it will save me lots of time and money.
This is one of the best guides to shop dust collection. In my nearly 50 years of furniture making, I have made most of the mistakes with my systems.If only I could have had this guidance many years ago! I now have mostly short runs, blast gates on all machinery, a single stage collector, and a cyclone. I hardly have any flexible ductwork. When I built my current house, I laid 4” pvc pipe in trenches before the basement slab was poured, coming up at each (planned) piece of equipment. It took a bit of planning and was a leap of faith, but the system has worked well over the last 28 years. Thanks for your great presentation.
I can't thank you enough for this. I finally get it! You rock James!
Volumes of content in a concise to-the-point format. THANK YOU!!!
Matthias Wandel recently posted a number of dust collection related videos, including one with hard numbers comparing a shop vac and a homemade induction motor impeller, and different sizes of hose. A good companion video to this one
He has also gone the route of building dedicated dust/chip solutions for many of his tools. Local =short distance and dedicated = more tailored air flow or pressure for each tool. Also gives redundancy in the room. Personally I think he just likes building things. :-)
Once again, you've come up with a ton of valuable info without wasting time on useless info. You really have a way of communicating great ideas!
You just saved me from a lot of mistakes! Clear and dust free tips as always. Thanks a lot!!!
Excellent, clear and thorough presentation. Thanks so much.I hope this presentation doesn't disappear, because there's an awful lot to remember and put into practice, when it comes to setting up my shop.
One of THE BEST dust collection explanation videos I've came across! Well done!
As always you have a way of boiling it down to the essentials in such a clear and concise way. Love your way of teaching!
Great video. Teaching people your previous mistakes best way to pay it forward.
I got a single stage Jet and didn't like the expense of the cartridge filters not to mention what it might take to clean them. I ended up attaching a round piece of plywood (routed underneath with a round nose bit for a tighter fit) to the top the the collector using the existing spring clips to hold it down that came with the machine. I made a hole in the top to accommodate the 4" PVC that comes out of the top and with an elbow attaches to a dryer vent about 1" away on the wall. The large chips fall in to the bag while the fine dust goes outside of my shop via a dryer vent.
I’ve watched a LOT of videos on shop dust collection. This one is by far the most comprehensive and understandable!! THANKS!
Love all your videos. Thank you for the all of them. This is perfect timing personally as I was wondering which route I should go as far as dust collection is concerned. Thanks again!
Been researching dust collection systems for a while now. This is by far the best advice I have seen when it comes to dust collection. Thanks, you’ve earned my subscription to your channel.
I am just becoming a fan of your instructional and review videos. They are the best in terms of detail and underlying rationale. You are also a naturally good presenter, using clear language, concise points, linear-logical progression. You are a very good teacher. The reliance that you have on your own experiences (both good and bad results) is a perfect exclamation mark to the points being made.
These fundamentals keep my growing shop running efficiently. Thank you!
I am putting together my first dust collection system now and this is pure gold! Thanks!
I went back today and re-worked my dust collector system today and moved the gates near the main feeds and the air flow really changed for the better. Great tip!
This is gold, I was just getting ready to try and figure out what I wanted to do for my first ever dust collection system
ditto
Always the best source for balanced and thoughtful advice. Thanks!
Great video with a lot of information packed into it. I was very glad that you made the statement that assuming you set your expectations properly, a single stage system may be fine for a small shop woodworker. With all due respect to Bill Pentz, the ability to install a semi-industrial 5HP+ cyclone system with 8" ducts and custom hoods on all machines is simply far beyond the reach of average weekend woodworker. While it would be absolutely necessary for someone exposed on a daily basis, for someone who might make a half a dozen cuts on a table saw every other week, such a setup is simply impractical. Too many internet dust collection pundits insist that your are just wasting your time unless you are going all the way to the extreme, leaving many to give up in frustration and go for nothing.
Amen true that
Thank you for sharing your expertise with simplicity and clarity. It is a rare treat!
I'm a silversmith, and you have provided outstanding information for this type of workshop. Many thanks!
After reviewing the video, I started looking through my dust collection system to determine any leaks that could be occurring on 6 blast gates... It hadn't dawned on me that the metal gates were installed the wrong way (tightner needing to be on the back side facing the intake hose to secure the seal when gate is closed). Wow.. closely inspecting the blast gates, I could see the small thin spacing between the closed gate and the intake. Reinstalled and did see significant improvement with the air-flow coming through now .. thanks Stub
Great info. Thank you. I would highly encourage you to try/review Oneida’s supercell system to add to your video series. It’s beyond incredible!
Great teaching as always. I value your experience and learning through difficult choices.
Love listening to your informational videos. You do a great job getting all the facts out to take into consideration.
Thank you for this video, you've just saved me a lot of money and time. I'll stick with my shopvac for the time being rather than buying all the pipes and fittings and a dust collector as I was about to do.
Let me be the first to say this was a "sucky" video with lots of useful tips. I'm heading out to my shop and shorten a couple of runs and tape up some leaky seams.
Thank you! I can tell you put a lot of thought into your videos. I appreciate them a lot.
Absolutely the best explanation of a dust collection system on KZhead. Thx
Once again, Stumpy shares verbal gold. I'll be setting up my first real dust collection soon, so this dropped at the perfect time.
Another great video. I am getting back in to wood working now that the kids are grown and out of the house. Thanks for all the insight. Making and figuring out your mistakes is by far the best (albeit painful at times) education!
Excellent video summing up a lot of knowledge the you'd usually have to sort through numerous forum posts to obtain. And I was looking into building my dust collection system today, so perfect timing!
Thank you so much. You covered everything I needed to know in order to find what works best for my small workshop.
I can picture myself making every single one of these mistakes. Thanks for the tip stumpy
But those are not mistakes? Not everyone can or wants to put 4k into a dust collection system amd have the best of everything.
Perfect timing James, I have been using shop-Vac for years and I am thinking of upgrading to a single-stage because I just bought a new table saw and the Shop-Vac just doesn't cut it. I have a very small shop in my garage and the tips that you have just given me will really help me make an educated decision. Thanks as always your videos Rock!!!
This is the best video I have found that provides a full explanation of dust collection. Great job!!
You have opened my mind to the options and limitations of each. Thank you for sharing and explaining too, hopefully many of us will learn from this Thank you
As an operator of multiple large industrial dust collections systems I would say this is an excellent collection of wisdom. We have a strict policy against “floor sweeps”, they are bad and very unsafe for large systems. If you need a floor sweep your system is not designed right. The only advice I would add is to look at the collection right at the source, are you trying to catch the dust or capture as it fly’s by the opening. Many machines are not designed well for efficient dust capture at the source. Thanks for the video.
This is true of older machines which although work efficiently preparing wood do not have any respect for ones lungs. So buyer beware.
I thought sweeps were a great idea. I'll stick to making a pile of sawdust on the floor and picking it up with the shop vac.
@Mike Dillon. I don’t have “working knowledge”, but rather “casual knowledge”. From from my work experience, shouldn’t all ductwork of this type and use, also be of a grounding type ductwork to prevent electro static discharge?
@@chriscarter7182 I think Stumpy has a good video on this topic.
@@charlieodom9107 Thanks for the answer. I retired from Boeing almost 6 years ago. We made titanium structures for the aircraft. In the production lines we developed, where ever titanium chips or dust were collected by vacuum, the portable vacuums were required to be explosion proof. One bench mechanic was using a small hand held pneumatic vacuum and it exploded in his hand. He wasn’t injured, just unpleasantly surprised. The root cause was determined to be static discharge in the canvas collection bag. We had a large central vacuum system in the building but the production lines we developed used portable shop vac’s and they were required to be explosion proof after that incident.
Excellent video, extremely well-presented with all the important tips anyone thinking about building a system would need :-) One niggle though: You repeated a common misconception about dust collectors, namely that running them with insufficient air flow will cause them to overheat. The opposite is actually true: When an impeller system is running with no airflow, the motor is actually under the *least* load. This is counterintuitive until you think about it in terms of what work it is that the motor is doing, namely moving air. The more it’s moving per unit time, the more power it’s consuming; the less air the less power. It’s important to note though, that most shop vacuums *will* overheat if you restrict airflow. This is because inexpensive models use the vacuum’s exhaust to cool the motor. When you block the airflow, the motor does less work, the same as in a big system, but the motor can’t get any cooling air, so it overheats. High-end shop vacs use a separate air stream to cool the motor, so there’s no problem if their intake is blocked. (My Fein Turbo II is built that way, and I assume other high-end brands like Festool are designed the same.) Oh - another little tip: Shop vac filters are generally pretty bad, in that they don’t filter very finely. Gore-Tex makes a filter that matches Craftsman “red band” filters, which fit not only Craftsman vacs but many others besides. I don’t think they’re true HEPA filters, but they filter much more fine,y than the stock paper ones. They’re expensive but last a very long time if you brush them off well whenever you empty your vac. You can easily find these on Amazon and elsewhere, just be sure to check their dimensions against the filters your vac uses. Once again, a fantastic piece; any woodworker looking at dust collection should see it!
Thank you so much for this video. I've been considering upgrading my shop vac to a single stage, and this has cleared up a lot of questions I had, and some I hadn't considered.
This is the best video on the internet on the subject. Well done sir!
I am so happy that you mentioned Bill Pence, he is the titan among mortals when it comes to dust collection. His encyclopedic guide to dust collection was maybe the first thing I ever found on the internet that made cable worth paying for.
I have nothing to say really, but I appreciate your content, and wish to help with the yt-algorithms.
Same here!
80% of my dust collection system is my broom. Love to upgrade some day.
My other 20 is a leaf blower
Thank you for all the informative tips. I'm in the process of setting up dust collection for my shop including my new router lift. This was extremely helpful!
Best information on dust collection I have found, very clear and easy to understand. Thank you.
I guess I’ll stick to blowing my garage out with my leaf blower. 😏
😂😂😂
same here
Yeah I honestly I still do that. Every tool can't be hooked up to a dust collector or I just need to make one cut so my shop still has dust everywhere. I think the dust avoidance system is second best to collecting it. A good squirrel cage fan blowing away the dust while you work is much more affordable and convenient .
Glad I'm not the only one who does that. This video makes me a little ashamed of my shop setup
I do that. Hahahaha!
I liked everything about your video except the part about starving the air flow thus causing the motor to overheat. As a retired HVAC tech, I've found that starving the air flow results in a lower load on the motor with a corresponding reduction in amp draw. Granted that the efficiency of dust collection suffers, but it doesn't cause the motor to overheat.
also the air that cools the motor is separate from the dust collection air
This was super helpful! I’m just getting my woodshop started and was about to make most of the mistakes you pointed out. Thanks for this!
Very helpful video. I will consider each of these areas of concern this week as I build my first dust collection system. Thanks for the valuable insight.
As an Architectural Technologist, I have a fair understanding of air flow and resistance from a time when we thought warm air heating was good idea. Nevertheless, you have taught me stuff I did not know and made me more aware of the stuff I should know. It just goes to show; "You are never to old to learn". Thanks, Stumpy.
A bunch of good tips. At approx. 6:00 you said a duct that is too large will cause resistance. That is not true but what it does do is decrease the velocity. A minimum velocity (3500-4000 FPM) is required to keep the dust/shavings suspended; otherwise they will collect on the bottom and eventually cause an obstruction. You should also note that when using PVC duct (or most any plastic), you should run a ground wire inside. The chips flowing past a plastic surface will create static electricity which in turn can create a spark. Dust can actually be explosive under the right conditions so you wouldn't want to encourage that.
All true! I came looking for someone that knew and commented this info. Also using shop vacs can be dangerous because the motors can spark acting as an ignition source. Static dissipative flex hoses are also a good idea for the same reason as the PVC pipe. Hope your comment gets more attention.
I wish I'd just watched your video first, it's more comprehensive than the 15 or so videos I've previously spent time watching on KZhead all combined. New Subscriber here.
Looking to get into woodworking on a more regular basis and shopping for dust collector. This is by far the best video I’ve seen on the subject. Because of that, I’ve subscribed. Fantastic layout and description of topics. Can’t say enough about it.... absolutely top notch. Thank you
Collecting "Dust" as opposed to "Chips" is a quite different thing. A relatively slow air flow does a good job at collecting dust because the particles are small and they are quickly slowed to where they are floating in air. Chips, on the other hand, have a lot more mass to surface area and will travel much farther and escape many dust collection systems. But these are usually few and are easily collected by other means. It is the dust that I want to get rid of because it settles on everything given enough time.
I solved the filter problem by venting my system directly outside. I live in the country and my nearest neighbor is a 1/4 mile away so no danger to others.
Great idea! I thought about doing that as well, but my neighbor is about 15 feet away! But I guess one could build a shed attached to the shop which houses a serious dust collector.
@@TubeHammel Just run a hose to your neighbors system when they aren't home!
@@boydmerriman He doesn't have a shop. I think he doesn't even know how to grip a hammer! ;-) But he is still a nice feller.
I was going to do the same but my concern is is the winter when it’s -20 -30c I would have to replace that air with outside air
Extremely informative video. Usually don't have the patience for any videos longer that 10mins, but I will actually be watching this again to take in the points better. Thanks alot!!
Thank you so much for all the details you provided. You have given me so much to inform my decision as to which route I take when I get there!
Just go the Matthias Wandel approach... and have a dust collector for every machine 😂🤣
That guy is smart, sometimes too smart and yet, at the same time, not so smart. His approach from the last that I've seen, is more of a bit of laziness on his part.
Great information. Instead of using a pleated filter, could you just vent the dust/ air outside. This will increase the air flow. I have a Grizzly 220volt system in a 600sq ft shop. I turn wood bowls, there is alot of sanding. Any pros or cons is appreciated. Keep helping us.
Two things: Install your filter and motor just outside your shop in a protected area; eliminate the fine particle passing through the filter bag into the shop. DON'T grind metal on sanders in a wood shop, sparks will cause a smoldering fire.
Throwing metal sparks into a pile of sawdust is indeed a bad idea, but it should be noted that piles of metal dust (from grinding) can also be ignited, even without wood dust present. Also, I think lung protection maybe didn't get quite enough attention in this video. Regardless of whatever dust/smoke collection system you may have in your shop, it's not going to get everything coming off of a machine. A half-mask respirator with P100 filter cartridges is a must-have for any woodworking, metalworking, or welding.
Brilliant! Thanks for saving me a lot of trouble and time wasted. I was getting ready to get some practice with most of the mistakes. Back to the drawing board I go.
Thanks for all the tips. I recently installed a shop system and have realized how hundred of speed bumps analogy is a perfect statement.
I havre a perfect dust collector. I just hand my son a broom.
Woot my hands at 6:06
You could be a model, a hand model.
Hey buddy one of these days I'm gonna pump the air outside through a vent the way you did it. Your video was a game changer for me. I don't have space for a big filter.
I like the channel name. I went to school with a guy we called 7/8ths. He'd lost the end of his left middle in a "table saw incident". He would also use that finger to flip you off to prove how much he didn't care to send the very best.
This was maybe the most informative video I've watched on you tube!!! Thank you!!!
It took quite some time over years to get my head around this stuff. It’s nice to confirm I got to the same place as someone else. Wish this was around when I started :-) Thanks for the concise coverage as always.
Stumpy: You mention using PVC pipe however, I didn't see any grounding wire in the photos. Do you ground your PVC piping ?
That's pretty much a myth, or an old wives tail as we call it. No need to ground, it's not going to ignite.
My recall is that he covers it in the video when they installed the PVC ducting when they moved into the post office. If memory serves he takes the stance that it's not needed (the density of chips/dust isn't high enough for sparks to actually ignite it). However, I think he then reasons that it's easy to add by using a copper wire linking occasional screws through the duct.

Hey James, You should know I've learned a number of useful things from you and your videos and appreciate the example you represent to the woodworking community. Believing you're a reasonable guy I do hope, since you've snipped a screenshot from my dust collection system: kzhead.info/sun/pM6CZdBspXhvdIU/bejne.html to post in your video as an example of what NOT to do in some, maybe even most, ductwork systems, that you'll do me the courtesy of explaining to your viewers the context of my system compared to yours. Regardless of your response to my hopeful comment I'm not going to point out things from your shop and/or workflow to my audience that are woefully lacking from my frame of reference... that would be both cowardly and disrespectful. Best regards, Matt Jackson Next Level Carpentry on KZhead
Hi, Matt. I'm going to give you the benefit of the doubt that you did not mean the "cowardly and disrespectful" portion of your comment since it GREATLY escalates what would otherwise be a simple misunderstanding of intent. I chose that image from Google not really knowing who you were. It wasn't personal at all. I needed a photo of a long piece of flex hose in a shop setting, and I found yours a little humorous. It was an important point that I was making, as I am sure you will agree. However, I admit that the image I chose lacks context, and I regret that. I own the same Harvey dust processor that you have and it produces an abundance of airflow for the size shop you own, giving you the luxury of using a lot more flex hose than most other woodworkers should use. I said as much while defending you in response to the comment I received about it below. Given that I neglected to provide context in the video I will pin to the top of the comments a statement about it. Because, as you said in the first half of your comment, I am indeed a "reasonable guy". Have a nice day, Matt :)
(This comment is now pinned to the top of the comments section, directly below the video.) IMPORTANT: In the video I show an image of a workshop with an excessively long length of flex hose. I found the image on Google and thought it was a humorous example of a big piece of hose. I neglected to provide context for the image. The gentleman in the photo was attaching that hose to a much more powerful system than is found in most small workshops. He could afford to lose some airflow from the long flex hose, and it works well for him. By not providing that context I made it appear that HE was making a mistake rather than my intended point, which is that most OTHER folks should not do that with their single-stage systems. I am sorry I didn't make that clear, which is why I have removed the image from the video thumbnail and I am pinning this comment to the top so everyone can see it.
This should be required viewing for anyone adding or replacing a dust collection system. Thank you!
Thank You James for bringing science and common sense to an oft disinformed subject. You're always refreshing and insightful to view. Well done!
EVERY SHOP should watch this. Great job. I learned a lot. Excited to apply what I learned. Thank you.
Great video as always! Very instructive it has made me look closely at my dust collection system and cleared up issues that I had. Thank you!
I've been eyeballing and trying to figure out a dust collection system for over a year now and this is been the best video out there to help me figure out what I need for my shop thanks a lot
Really a superb summary...as usual. I'll be coming back to this more than once. Thanks.
This video saved me hundreds of dollars. Thank you so much. I was in the process of ordering plumbing for a new system. You made many great points.
Excellent video. It helped make sense of a number of issues I have encountered trying, unsucessfully, to manage dust in my small DIY workshop. Thank you.
Excellent video! You just made me rethink my entire dust collection design and probably saved me at least $500. I'm going to keep things simple and as you said, use the right dust collection tool for the right situation. Thanks again!
Thanks for being so honest and thorough. Your tutorial videos come highly recommended and I have watched a few. My good friend, neighbour and relative told me about your site and as an avid woodworker he was my woodworking mentor. Unfortunately he passed away two days ago. I thought it only fitting to revisit one of your videos in his honour. Thanks again for your guidance.
Great video! Clear, to the point, and well organized. Thanks!
This is an absolutely fantastic video. After watching three others that didn't even touch on the conceptual aspects of dust collection I found and devoured this vid, which walks is through the key precepts involved in putting together effective dust collection systems. All I needed (as he did the research for us) to move ahead with my planning...
Exceptional overview. Thanks for pulling this together.
A complicated subject very well presented and demystified. Thank you!
Very thorough video. Nice content, and thanks for sharing the lessons you had to learn the hard way. Feeling more prepared to build my set up.
Great amount of info, James~! I'm in the process of putting together my shop dust collection, so this was right on time. Thanks much~!!
Excellent video - has made me significantly change my plans. Thank you
Here I was thinking my 2.5 gallon shop vac was so awesome. Thanks so much for putting this video together, super helpful!
James, once again, a good summary and discussion. Thanks, and keep it up.
Terrific review. I definitely appreciated seeing your mistakes so we wouldn’t repeat them. I would’ve liked to see more of your final system though, maybe the pros and cons of where you ended up.
Great video! I've made a few of these mistakes, but have my head set straight now with my current system. ClearVue CV1800 beast!
Thanks this is good food for thought, I'm getting to the point where I'll need better dust collection soon, and this is a good starter reference on the do's and don'ts of the basics
Thanks Again for sharing your journey. The knowledge you have gathered and shared from you experiences will save a great many people many years, dollars, frustration, and disappointment. Very well Done !
Great tips on this subject!! Great job on the video! What I got from this is Air Flow, Air flow, Air Flow.
Thank you. A lot of good information here and things I will apply to my system. I particularly appreciated the caution about inadvertently introducing metal objects from a floor sweep collector and the potential for a fire in the dust container. TJ
I built a small shed attached to the outside of my shop. Instead of a container and filters, I simply blow everything outside into the shed. I can then scoop up the shavings etc. with my loader to use as bedding for chickens without having to haul containers around.
