I've watched every dust collector build Matthias has put up here on YT. You'd think that maybe it'd start to get boring. But NOPE. Still as interesting as the first time I watched one.
Very cool build. I was thinking of building something just like this. Good to know about the furnace filters. I will just use my old ones that are in my furnace.
Hi Matthias, My name is Emma and I absolutely love ur Channel I watch all of your videos some of them multiple and I find all of this stuff so interesting and cool and I wanna be like you some day but I don't rly know what I am doing as I am only 17. I think you are the coolest person I have ever heard of and I aspire to be like you someday. Your videos always make me feel better and help me learn a lot of cool things. I was wondering if you could do a video on the basics of motors, making machines and like electrical work with wires and making switches and what not.
The DW735 is such a pain in the ass to work with. It works but man, between the built in blower, the noise, price, and the fact it throws sawdust 20+ feet and blows all the seals on standard dust collection.... thing is just a pain to deal with.
Fantastic and A1 all around. Move over Norm, he looks a lot like you 30 yrs ago and he even wears boat shoes. Porter Cable where are you? I'm seein' ads for everybody else here...
Ever since calculating watts here in FL when working with LED lights, it amazes me how cheap electricity really is. 229 watts only costs about .02 cents an hour.

Mathias,, a bit of research and discovery on the MERV ratings of the filters you are using and the effectiveness of particle size removal would be helpful. The filter you describe as not designed for dust removal, is for just that. The MERV rating will give you the particle size removed and type of particles being removed. MERV 8 Is adequate for most shops if placed properly with adequate air flow.
Yes, it's designed for dust removal, but it's a completely different sort of dust removal. These filters aren't meant to get caked in dust. The MERV rating is kind of irrelevant once it's caked.
hi matthias! why dont you measure de difference in suction and head? i think centrifugalpumps are better at head than at sucking pressure,so if you force your air though filters its possible jt works better.
Matthias Wandel Wood woudnt Hurt your blower i think? if could be worth the try. or you could glue soms aluminium plate on the Wood? i would be interested in the difference in pressure you could achieve. especially that the filters block neef soms pressure tot work well. or you could try the other design for the filters you use in you shop tot clean the air of small particles. kind regards
Hi Matthias, I really enjoy watching your projects. I just wonder if you've ever consider epoxy fiber glass your dust collector. Would this be beneficial at all in wood projects. It would create better seal! just a thought! Nooran
I've been wondering, how would this compare to the blower out of a vacuum cleaner? I salvaged one out of a broken vacuum cleaner a while ago, and it's so much smaller than this one, yet almost the same in design, and it seems to generate plenty of suction and use a tiny motor (As a vacuum cleaner that is, I did not make it into a dust collector). Have you ever considered picking a vacuum out of the trash or such to save work in making a dust collector? Is it just too loud?
Quick question. Why don't you design a designated dustcollection system with pipes in the "unseen" corner of your shop or next door with the storage? Sort of just like Marius has it installed.
Hi, so i want to hear your opinion on building my own dust collection system. I just finished building a 100 sqr meter workshop, what kind of system would you recommend me to build? I am going to use pvc pipes for it and the other flex pipes to the machines.
MAY BE THE DUST COLLECTOR CAN BE TURNED INTO ELECTRIC JET ENGINE AND CAN BE VERY POWERFUL WITH SOME ALTERATION AND MORE HIGH TECH MIXED METAL WOOD COULD DRIVE A BOAT MORE LIKE FUTURISTIC S BOAT AND PLAIN WITH OUT PILOT
I watched you using your table saw to remove the laminate from the edges of the bottom panel. You’re wearing a long sleeved shirt with the cuffs unbuttoned and hanging very close to the saw blade. I kept cringing thinking this was one of those tragedy videos where your cuff will be grabbed by the saw blade and do you unimaginable harm. Please, be careful. Button your cuffs or better yet grab some masking tape and wrap it around any loose clothing.
he started this video saying the motor was too big so he increased the size of the fan blades and now he needs a bigger motor but then that motor will be too big so he will have to increase the fan blades again but then he will need a bigger motor........
Pol Feliu Cuberes ahhhhh but there is the tech/woodworking/maker #1 Adam Savage. He's said recently that he watches Matthias regularly. I tell ya what I'd like to see. An Adam Savage and Matthias Wandel mash-up and collab.... Adam visiting Matthias' shop and Matthias visiting Adams shop! 2 smart guys... Total bromance Matthias? Or mutual admiration society? 😊
It was watching videos by Matthias that got me into wordworking as an escape from my day job as a software engineer. I find having something physically "made" at the end of a session in the shed is more rewarding than 8 hours of grinding out code, no matter how fancy it is.
I just finished building a new shed, 10' X 12' with 8 ft tall walls and a 3/12 roof pitch and I'm literally jonesing to get it outfitted, electrified and made into a woodworking shed. Can't wait to get some of Matthias's projects started!! 😊
That motor is likely assigned its current rating based on 40 C and stagnant air. You can always get a little more of it the motor when your conditions are more mild than that. In fact, in the HVAC industry, manufacturers will retest nominal horsepower motors and rerate them to whatever they can get. I've seen a 3 HP motor get rerated to 4.5 HP because it's in an airstream and the airstream never gets over 25 C.
"1/10th horsepower motor" 1 hp = 750W 1/10hp = 75W 1.8A at 110V = 198W 198/75 = 2.64 Am I missing something, is this being run at 250% rated power or is it actually a quarter horsepower motor?
Of course, that's my mistake - I'm used to dealing with R/C motors which are rated in electrical watts, with who knows how much output power, but this is rated at 0.1hp mechanical power output. Definitely a useful thing to remember!
An Impeller/Housing generator program would be a nice idea! Just enter the impeller's diameter, and the 1:1 template is done... A bit like the gear generator
Can't you use the air output of the dust collector to cool the motor? This way you could run the motor with a higher load. Motors are rated to a maximum power mainly because of temperature limits.
I find myself always excited to see another video on blower designs. Something about it is like the ultimate in home DIY experimentation with the methods and results.
I wonder if you could add a vibration motor using an old speaker or something to help shake the dust off lol probably over kill but would be a fun project
With your obvious mathmatical, physics, and machining knowledge/understanding I assume your job is in one of the engineering fields. I also know you use SketchUp for all your CAD drawings. If my assumption is correct then you surely know of AutoCad, Autodesk Inventor, Solid works, NX, and other software with much better and easier ability. Why not use one of them? I know that some can be very expensive but they do have trials and educational versions that are cheap if not free
Mattias, eres un Genio del bricolage. Disfruto de tus videos y trabajos. Sigue así y gran saludo. Mattias you are a DIY Genius. I enjoy with your videos and your works. Keep it up and greetings
Matthias try to find a blower from an old hot tub. The one I used for my system is 220 volt, supposedly 2 hp with very high static pressure because it is designed to force air into the jets. They are easy to find in the back of any pool or spa place and free. Like you, the only thing I bought were the hoses and fittings. I'll send you photos of my complete system if your interested.
Matthias Wandel yes very low and that is why I don't use gates. Instead I just move the hose around. 4" hose doesn't really help over 2" either. If I'm not careful and I accidentally deadhead the intake it will collapse my garbage can / thein baffle. lol it's been working for 3 years and I I'm happy with it... especially the price. Considerably quieter than other setups as well.
I have a 200V 2.2 Kw 3 phase 3 HP motor powering a large squirrel cage blower. I need to find a very large separator and filter to make a complete system. Being in Japan I don't have access to wood working stuff much so would you build a separator and mount to a trash barrel and put on a filter bag 2nd stage or what?
Matthias, i remember you talking about the availability of these filters in Europe. I'm not sure your european subscribers know what you exactly mean with 'furnace' filter. Do you know how they are known in- for example - Germany or the Netherlands?
Are you planning to compare this one head-to-head with your Small Dust Collector (the bucket unit) or was this just a fun experiment? Seems like emptying this one is a bit of a messy job.
You can make your drill press into drum sander, just make simple box wood that can easily be clamped on drill table, make hole slightly bigger than drum you make and glue sandpaper on that has drill chuck attachment point, add side hole to box gto vacuum dust. Done.
great job with the blower design. power consumed is a function of the impeller design. It's the only part that consumes power. the only reason I bring that up is cos at one point in the video you tried to reduce the power consumed by changing the volute design. if you ever want to try a new impeller design I can make up one in some proprietary software I use at work, to match the incidence angle, and with about 45 deg backward lean at the end.
This video seemed to be made with less enthusiasm than others. I hope he's not worrying about producing content rather than actually enjoying producing it.
Have you, or has anyone else, made a cyclone dust collector from a furnace blower and motor? I don't want to have to build the fan blades and blower like in this one. Wondering how well it would work.
I feel that your diffuser (the scroll) is not optimal. The idea of a diffuser is to slow the air down as it comes out, to increase the exhaust pressure so that it can best push the atmosphere out of the way, thus relieving the motor of work to do. In short your outlet is too small, so the air is still travelling too fast which wastes energy. Optimally it needs to be 3 times the diameter of the inlet, That is 9 times the area, so the air is travelling at one ninth the speed recovering 81% of the energy.
Why don't you incorprate a shaker, with maybe a tray in there to catch the finer stuff you shake off the filters? make them slide out to empty! great build, though!

Such a professional woodworker, dewalt sends him tools yet off brand drills are his favorite
Very cool build. I was thinking of building something just like this. Good to know about the furnace filters. I will just use my old ones that are in my furnace.
Duct tape, tiny scraps, and maxing out the power rating of the motor... truly a man after my own heart!
Excellent video
Hi Matthias,

We are so lucky that Matthias uses his powers for good.
The DW735 is such a pain in the ass to work with. It works but man, between the built in blower, the noise, price, and the fact it throws sawdust 20+ feet and blows all the seals on standard dust collection.... thing is just a pain to deal with.
i love how you recycle every piece of wood :) and not throw it away
Fantastic and A1 all around. Move over Norm, he looks a lot like you 30 yrs ago and he even wears boat shoes. Porter Cable where are you? I'm seein' ads for everybody else here...
I also have problems with dust blow by . Looks like I need to step and puck up some masking tape instead of foam tape. Thanks for the obvious answer.
Dude, you're the best. I hope you reach a million subs so bad.
I think this is the most Red Green looking project from you.
Always a pleasure, thank you Matthias
I think I'm more excited than Matthias for this channel hitting one million subscriber soon.
Seeing you cut the duct tape with scissors was real cute. it very easily with hands and keeps a straight line, like some fabrics.
I wonder if he found the carboard box in the trash.
Ever since calculating watts here in FL when working with LED lights, it amazes me how cheap electricity really is.
229 watts only costs about .02 cents an hour.

Yes, the effectiveness of any filter is hindered when caked. Maintain or change filters regularly.
6:44 ingenious solution!
Great video (as allways).
4:52 look out for your sleeves Matthias!
muy bueno me gusta gracias
Matthias would you ever consider making like a tips and tricks video?
lol my dust collector draws over 20A. I think I went a little overboard, considering it uses a shop vac hose.
Another great video, thanks!
Nice project
At the end of the day....Matthias is Tim the Toolman.....MOAR (deliberate misspelling for effect) POWER!...insert guttural grunting.
mad but great! now make some mind bending furniture!!!😊👍
hi matthias! why dont you measure de difference in suction and head? i think centrifugalpumps are better at head than at sucking pressure,so if you force your air though filters its possible jt works better.
that would require putting the debris thru the blower, which would require a less efficient style of blower (and also one made out of metal)
Matthias Wandel Wood woudnt Hurt your blower i think? if could be worth the try. or you could glue soms aluminium plate on the Wood? i would be interested in the difference in pressure you could achieve. especially that the filters block neef soms pressure tot work well. or you could try the other design for the filters you use in you shop tot clean the air of small particles. kind regards
Hi Matthias, I really enjoy watching your projects. I just wonder if you've ever consider epoxy fiber glass your dust collector. Would this be beneficial at all in wood projects. It would create better seal! just a thought! Nooran

Have you ever considered picking a vacuum out of the trash or such to save work in making a dust collector? Is it just too loud?
Vacuum cleaner blowers are super loud, consume lots of power, and don't last very log
Hi Matthias. Is there an optimum motor/impeller that you think would do the job for you 13 inch planner?
bigger is better.
Whoa slow down on the bandsaw! seems dangerous
Quick question. Why don't you design a designated dustcollection system with pipes in the "unseen" corner of your shop or next door with the storage? Sort of just like Marius has it installed.
because those spaces are occupied, and because I'd need some really long duct runs
Hi, so i want to hear your opinion on building my own dust collection system.
I just finished building a 100 sqr meter workshop, what kind of system would you recommend me to build? I am going to use pvc pipes for it and the other flex pipes to the machines.
Маттиас ! береги руки заверни рукава на рубашке очень страшно смотреть как ты работаешь на распиловочном столе .
You misspelled dishwasher in your description.
yeah..nice..
A bigger motor, I knew you would say that
Молодец Матиас !!! :)
MAY BE THE DUST COLLECTOR CAN BE TURNED INTO ELECTRIC JET ENGINE AND CAN BE VERY POWERFUL WITH SOME ALTERATION AND MORE HIGH TECH MIXED METAL WOOD COULD DRIVE A BOAT MORE LIKE FUTURISTIC S BOAT
AND PLAIN WITH OUT PILOT
ALGUEM AVISA PRAELE QUE ELE VAI ACABAR PERDENDO A MAO SE CONTINUAR NEGLIGENCIANDO A DISTANCIA DA SERRA
COOL!!!
10:12-10:41 can you please tell us where you got that vacuum pipe/nozzle from?
probably busy bee tools, or lee valley tools
Hm, the bard code is still on it you can probably check that
your long sleeves close the the tablesaw blade scared me for a sec.
you're like a band saw savant
it's gonna need 1.1 gigawatts!
what the hell is a gigawatt?
Silvio Nunes you mean 1.21 gigawatts
woah woah woah, hes trying to make a vacuum, not travel through time.
im just here for the moccasins

Can you put any images in your big print program?
See here: woodgears.ca/bigprint
Do you can speack German???
And of course a awesome Video!
It seems to be a theme of your dust collectors that you "Should have used a slightly larger motor". Almost every video ends with that same line.
that's because I always size the blower as big as I can get away with with the motor that I start with
In 10 years your dust collector project will be 10 shipping containers with a hemi to power the blower.
"...but if I had it to do again, I'd probably use a Detroit Diesel."
he started this video saying the motor was too big so he increased the size of the fan blades and now he needs a bigger motor but then that motor will be too big so he will have to increase the fan blades again but then he will need a bigger motor........
Dave L I’ve found this black hole that I can use as a dust collector but I wish it was just a tiny bit more powerful
today, Matthias will build a cardboard box out of wood . . .
Wut? Mattias using tape all over the place... what has happened!
Affra, hard to compete with duct tape, lol
Affra this video was sponsored by duct tape
its duct tape. thats literally its designed purpose
Not for broken ducks then?
What Matthias doesn't tell you is that these videos aren't sped up.
I love the incredibly loud yelling over the noise of the fan blowing - it's just so great.
Oh, and so is the build and video too!
The RUclipsr in me wonders why you don't put RGB lighting inside it... then I realise i'm not watching LinusTechTips.
Mark Randall just when i though i was the only person in the world that was into woodworking and "tech"
Pol Feliu Cuberes ahhhhh but there is the tech/woodworking/maker #1 Adam Savage. He's said recently that he watches Matthias regularly. I tell ya what I'd like to see.

loved watching this come together! Also glad that even you have to rely on tape every now and then. Hard to beat when in a pinch, right?
lol ur here wow
LOL, that part with the cardboard pieces looked a lot like my projects. Cereal boxes are actually my #1 template making material. ;)
I think you should rename your channel to "I should use bigger motors for everything I'm doing", because 2 in 3 projects seem to be underpowered.
When you wish to produce quickly, you must always have your three drills! One for drilling, one for countersinking, and one for driving!
How many fuckin dust collectors do you have now?
If duct tape isn't the right answer, you're asking the wrong question!
That motor is likely assigned its current rating based on 40 C and stagnant air. You can always get a little more of it the motor when your conditions are more mild than that.
In fact, in the HVAC industry, manufacturers will retest nominal horsepower motors and rerate them to whatever they can get. I've seen a 3 HP motor get rerated to 4.5 HP because it's in an airstream and the airstream never gets over 25 C.
"1/10th horsepower motor"
1 hp = 750W
1/10hp = 75W
1.8A at 110V = 198W
198/75 = 2.64
Am I missing something, is this being run at 250% rated power or is it actually a quarter horsepower motor?
Yes, you missing that these motors are not that efficient. It takes 80 watts with no power coming out at all.
Of course, that's my mistake - I'm used to dealing with R/C motors which are rated in electrical watts, with who knows how much output power, but this is rated at 0.1hp mechanical power output. Definitely a useful thing to remember!
So if a have a Brushlessmotor and it says it has a power of 1500watt, is it now mechanical output or electrical input?
Megaspasstpräsentiert yes.
Ant Mallett power out divided by power in. In this case 75W out / 198W in is about 40%.
I'm 63 years old, I'm a carpenter, and I've always tried to make my machines, recycling everything
That is awesome I would also enjoy Learning this skill I'm a budding contractor myself learning under a general contractor as we speak.
An Impeller/Housing generator program would be a nice idea! Just enter the impeller's diameter, and the 1:1 template is done... A bit like the gear generator
Can't you use the air output of the dust collector to cool the motor? This way you could run the motor with a higher load. Motors are rated to a maximum power mainly because of temperature limits.
Did you think of using a cyclone design to make the filters last longer ?
The blower isn't powerful enough. Too much pressure is lost in the cyclone. Might as well use some of that pressure to get the air thru the filter.
Nice cameo appearance by your daughter , screwdriver in hand already
"If I was to build it again." Come on Mattias you're fooling no one. We all know you'll be building a new dust collector within the year.
I find myself always excited to see another video on blower designs. Something about it is like the ultimate in home DIY experimentation with the methods and results.
I`ve watched all Your Clips, and its marvelous to see how you have become a top notch reporter :) Very good videos , thanks!
4:54 your sleeve could possibly get cought in the blade, after some seconds again. It would be really horrible....
He made a video of trying to get a piece of cloth to snag in a table saw. After reasonably extensive testing he decided he is probably safe.
My wife has asked me to fix our bathroom tiles for 5 years I said to her that duck tape will do.
are they birkenstock shoes? And yeah, you know what you are doing alright, but as someone already said, watch your sleeves bud.
what happend to the cyclone dust collector as a first stage?
How is the little shop helper? I bet she is growing up fast. Oops, I commented before I watched the whole video. 8^)
I wonder if you could add a vibration motor using an old speaker or something to help shake the dust off lol probably over kill but would be a fun project
I wish I had 1/10 your ambition, a little of your intellect wouldn't hurt either. Thanks.

Harriet be like, "I'm going to build a table out of this thing I found this in the dumpster"
you're a mad woodworking genius. I barely understand what you're saying half the time and I love it!
Matthias, do you work on your own vehicles or tractors? Something with those would be interesting to watch.
Have you tried a "push" collector with the dewalt planer? I built a Thien separator for mine and the blower in the planer is strong enough by itself.
Mattias, eres un Genio del bricolage. Disfruto de tus videos y trabajos. Sigue así y gran saludo.
Mattias you are a DIY Genius. I enjoy with your videos and your works. Keep it up and greetings
Matthias try to find a blower from an old hot tub. The one I used for my system is 220 volt, supposedly 2 hp with very high static pressure because it is designed to force air into the jets. They are easy to find in the back of any pool or spa place and free. Like you, the only thing I bought were the hoses and fittings. I'll send you photos of my complete system if your interested.
I'd be curious about one of those blower. I would imagine they are designed for very low CFM
Matthias Wandel yes very low and that is why I don't use gates. Instead I just move the hose around. 4" hose doesn't really help over 2" either. If I'm not careful and I accidentally deadhead the intake it will collapse my garbage can / thein baffle. lol it's been working for 3 years and I I'm happy with it... especially the price.

hey matthias ! im a fan, can you consider making an automata? or automaton as others say, more power!
Are you planning to compare this one head-to-head with your Small Dust Collector (the bucket unit) or was this just a fun experiment? Seems like emptying this one is a bit of a messy job.
Yes, messier. But it has about 3x the capacity before it needs emptying
You can make your drill press into drum sander, just make simple box wood that can easily be clamped on drill table, make hole slightly bigger than drum you make and glue sandpaper on that has drill chuck attachment point, add side hole to box gto vacuum dust. Done.

This video seemed to be made with less enthusiasm than others.
I hope he's not worrying about producing content rather than actually enjoying producing it.
8:48 Is that your nephew, Matthias?
he's cute also didnt think he'd wander to your workshop.
Have you, or has anyone else, made a cyclone dust collector from a furnace blower and motor? I don't want to have to build the fan blades and blower like in this one. Wondering how well it would work.
Forgive me but this is one project that leaves me asking....WHY? these so called dust collectors look like a maintenance nightmare.
