Mathias, you are a young gentleman with a great command of logic and the beauty of engineering and scientific wonders. Congratulations on your ingenious resonating chamber found in any kitchen and placed such as to create a destructive wavefront which is in antiphase with what is coming out of that blower.

I love the fact that you don't mind leaving the OOPS moments in your videos. You are a master so it doesn't detract from it at all.

I LOVE that you made a lock nut out of wood. Just because. You're like a 1 man industrial revolution, going through all the trials and errors of the evolution of modern equipment. They make lock nuts now for fractions of a penny.

I worked at a cotton gin where very large centrifugal fans were used. They are extremely loud and some can be heard from a mile away. Eventually someone came up with an idea for a muffler. They were designed just like an automotive muffler, but had to be really oversized to prevent backpressure and a reduction in cfm. Interestingly, some fans were quieter with the fan on the intake side while others benefitted more with on exhaust muffler. After two or three years of trial and error the mufflers lowered the noise by 70 to 80 percent. The mufflers were just metal boxes with internal baffle plates. I can't imagine spending the time to build one of these for a dust collector, but it seems like you'll try anything!

Having lost part of my hearing from continuous noise exposure I'm wondering, if the companies that make and sell us the power tools we use, put even a fraction of Matthias's effort in making them less noisy. Dust free and - let's all hope - noise free workshops for all! Good job and great thinking Matthias! Might I suggest, the use of a transparent strip (plexi or acrylic) embeded to the side of the bucket, in order to eliminate the need for a light source? I know that heat and wattage are not an issue with LED lamps, but it would be 'one thing less' in the whole design.

What I especially like about your videos is unlike most people I know, you will admit when you've taken the wrong path with your mistakes. Thank you. Trying it again makes us better at our craft.

I am quite liberal when I hand out likes on videos. I give them out for being entertained (fairly easy to get), for inventiveness (a little tougher to get), for teaching me something ( and a bit tougher yet) and then for blowing my mind and I have to share with everyone. You videos consistently meet or exceed at least 2 of my criteria. I love the stuff you come up with. Thanks for sharing.

I love the fact that you paint all of your homemade equipment green!!! I don't know if it's because your favorite color is green (it's certainly mine) or what but keep on keeping doing what you're doing! I love watching your videos! I must've watched each of them about 5 times!!!!

What an awesome job. You are like a treasure for humanity. I wish for you to live along life,so we can learn from you. God bless you.

That back light makes things much more interesting, almost makes vacuuming fun! Can't wait your next video. You are amazing guy!

That Maple Syrup can was the cherry on top! Awesome idea.

Creo que hablo por todos los que vemos tus videos y estamos agradecidos por tu formación didáctica de explicar todo en una forma tan sencilla y tu tiempo para filmar y editar para todos nosotros. Mil gracias.

This channel is amazing. I can't believe all the things you are doing in just this video.

Great job Matthias! You're ideas and end products are amazing! I like watching your videos.

you do have some very interesting ideas. the cyclone dust trap is basic and brilliant. it's better than using a shopvac on it's own. the fan is pretty good too; it's not hard to build a fan, but it is fairly hard to build one that works as well as the ones you have built. thumbs up from me mate

Another option for a runaway nut is to drill through the nut and shaft and install a cotter pin. Found a box of them at Harbor Freight. Making a lot of changes to my little 2-car woodworking shop and the kit is a Godsend.

hey matthias i love yuor videos i like to watch them when im bored

Loctite, take a tip from the car guys. nuts and bolts tend to vibrate lose in certain places on vehicles. Check them out and see which one would be best for what your needs are, they have several kinds. try not use any stronger than you need because they can be real hard to get off. Also you could have used a self-locking nut and or a lock washer. Love this dust collector project!!

I just purchased and downloaded the dust collector plans. I'm a new woodworker so I hope to be able to build this. Otherwise I'll remain a beginner since I don't want to run tools without dust collection.

I realize I came late to the party, but if you run into a similar problem like that nut backing off in the future, I have a suggestion. You can drill a small hole through the bolt, and use a castle nut. They are commonly found on ball joints on a car's suspension. It looks like the rook on a chess board. It allows you to tighten the nut down, and adjust it so the relief cuts line up with the hole in the bolt. Run the cotter pin through the bolt, and you're good to go. Thank you for posting all these videos. They are greatly appreciated.

hmm.... Loctite® Threadlocker Red 271™ is great for Securing nuts and bolts from accidental loosening. Heavy duty; removes with heat and hand tools.

"So I've gotta take this sucker apart..." Heheh... I see what you did there.

Hi Matthias, I really like your way of egineering and problem solving! Thanks a lot for sharing!

Another fine build. I imagine the noise is some harmonic of the number of impeller blades passing by the opening per second. Curious that the tin can was enough to cancel it. Another idea I've seen used on propeller type fans is to vary the gap between blades and vary the pitch. Some blades generate their noise at their frequency and other blades generate their noise at their frequency, but the energy is spread out through the spectrum so it doesn't sound as loud/annoying.

I made a tiny dust collector that is closer to a shop vac than anything. It mounts on the top of a bucket and is somewhat cyclone based. It runs off of a small 60w blower fan I found in a dumpster, and works perfect to keep my bandsaw clean with the vacuum port on the back. The filter is a section cut out of a furnace filter and made into a lampshade shape, and it just hangs inside the collector, similar to a shop vac. The filter does obtain dust, but after cleaning my tablesaw dust off the floor, I easily had enough suction to clean up wood cutoff chunks off my bandsaw from making gears.

awesome build, as always. The can effectively is acting like a car muffler - its not really possible to eliminate sound, but you can slow down its dispersion, which is what mufflers do (and your can) - some of the sound goes away from it, and some goes into the can, and comes out more slowly, effectively becoming more quiet. The size of the container and any baffles inside also affects tone which can be more or less pleasant.

Totally blown away how you problem solved and fixed the nut that kept coming loose on the arbor and the frequency changing / hiding yogurt pot.... absolute genius! Are you a engineer by trade?

Great job, I think I'll get the plans for this. I've been using my big shop vac, but of course with no cyclone the filter just gets blocked up before the vac is full. Love your noise reduction device, very clever

Very creative and totally enjoyable! Thanks so much for sharing. Loved the note to the nitpickers about the light - hilarious!

Could blue loctite be used on the bolt?

I like the lock you made for the nut. A good alternative you could try for the nut if you didn't want to use loctite is fishing line. Run it through like your making a necklace outta the nut then screw it down. It makes it into a lock nut.

A piece of expanded metal lathing works great for adding pressure to nuts and plates. But you are the first person i have seen to use a yogurt doppelgänger in their shop. Good work.

Good job. Is the light there to inform you or entertain you? I could watch that swirl all day, but then, I have a sad life. Best Wishes, Brendan.

Looking good! I like how compact the whole thing is.

What a beauty in the end. And Wandelgreen.

Cool build. Looks like it works great. That vortex/cyclone dust separation phenomena is mind blowing. That will save endless hours of blasting filters clean... or $ on new filters.

Nice work Matthias! The noise cancellation was a stroke of genius. As you know these things are inherently noisy. If you have a way to measure decibels I'd be curious to know the results. I'm thinking this may be portable enough for both my basement and garage. What's the overall weight of machine? You may want to put this one in production - the weight to power ratio, low noise induction motor, and of course the unique wood construction may have provided us with a world class quiet, powerful DC for the masses. I want one and will start building one as soon as I can. Please keep up us updated on your detailed plans, improvements, etc. Thank you!

Matthias, why not paint your muffler too? I thought that was quite a clever solution to the noise level. Mike @ Doobly-Do Wood Works

one suggestion... Why not make grooves in the trailing edge of the Impeller fan, to mimic the wings of an Owl.. That way the the turbulence at the ends of the fan blades shall reduce and result in a more silent operation.. Cheers with the Cyclone... The backlght idea makes it look so bloody cool... it's mesmerizing..

Your "usual shade of green" reminds me of a trip up the Alcan Hwy in in 1965. There were a number of new iron bridges, every one painted a certain shade of blue. Every other man made object that was painted was also that same shade of blue. Where did Wandel Green originate?

Looks great Matthias

Техника исполнения хорошая. Здесь было бы целесообразно вентилятор поставить сверху, всасывающим отверстием вниз. Получилось бы значительно компактнее и на одной перегородке можно сэкономить. И вообще есть реальная возможность оформить это одним блоком и одевать на любое подходящее ведро. Не надо никаких пылесосов и циклонов! А в качестве электромотора можно использовать, например, дрель. Если убедил - пользуйтесь без каких бы то ни было ограничений. Удачи.

You could rise the suction ability by reducing the diameter of the flexible pipe. You would have more air speed.

Hopefully you're using the right kind of led bulb. Crappy ones can get really hot.

Matthias вы молодец.Всегда смотрю ваши ролики.

to keep that nut in place you can put a little of silicone, is good in vibrations and could be remove in future.

Nice build. It's actually kinda cute..... Now I cannot imagine how you went into the kitchen on day and said " hey, I'm in the mood for yougurt and I'm pretty sure the container will muffle the sound from the dust collector" :-)

I laughed when you were drilling through the metal and it gripped on, and for the second hole you just kept it in your hand again. I had some shop classes in highschool, and they taught us to always use clamps and stuff when you're drilling, no matter how long it takes, even if it's just for one hole, because you should rather lose time then fingers. If I'm honest, I've never used clamps for that purpose again after the end of those classes.

You have a fantastic mind for mechanics. Genius!

Hi i have just completed a similar setup to yours and it works well but i have come across an issue that is rather annoying if i inadvertently block the end of the hose while cleaning up the sides of the bucket collapse is this something i have to put up with or other than making sure i dont block the hose end is there a suitable fix.thanks in advance.

I liked your green tools so much, I went back and painted all my rolley tool tables "Deep Forest Green" oil based Rustoleum ®. Much cleaner, more uniform. Every bit helps.

I love seeing fellow engineers work through finding solutions.

Very nice as always, just take care that the heat of the light do not melt the container

Loctite may be the answer of your loosen bolt. Also In some non critical parts i used CA Glue, i didnt try CA on this kind of big bolts but it always worked well on model airplane parts.

you can make a branch resonator. most air filter boxes in cars have it to cancel out that noise frequency.

For some reason I like every one of your videos I watch. Am I becoming "Wandelified"? One question....do you worry about the light bulb ever melting the plastic? My grandmother kept lights on her baby chicks and some of those could get crazy hot.

Clearly, what this man needs is welding equipment in his inventory.

Looks great, the light is a nice touch too :)

Very nice job! For the loose nut, you could use a lock washer ou an auto lock nut!

Another great project Matthias - thankyou.

Brilliant work and ideas. Love your videos.

You must get a great deal on that green paint. Great project on the cheap.

nice work! I like the bulb gives it a cool look. but why not building a proper muffler?

I love watching your video's, i wish my health would let me fool around in my little shop, you make some real cool stuff ! thanks for the video's

you should make a video comparing the noise levels of the normal vacuum to the one you created.

Dude your dad comes up with some great ideas..

It would be intreasting to see how this one compared to the two colectors you showed us in December. Both for suction and loudness. Very hard to guage sound in a video.

You forgot to paint the can LOL great job Matthias as always

Matthias and his green machines, that's a great title for a children's book

if u ever have any future problems with that nut coming lose may i suggest: either a castelled nut, safety wire, or metal lock nut tho these can be hard to find. things like castelled nuts, safety wire for your application can be done diy tho i hope ur fix works with out any future problems :)

Matthias, I am really excited about your invention. I am very adverse to loud noise and threw out my shop vac cause it was just too damn noisy. Your design incorporates many noise reduction designs and tricks. Still, I am wondering if you could give us some overall decibel numbers and compare levels to your other collectors?

Great Build Mathias! I could do everything but the large motor. We didn't see how you made that. Is it in another video? ~Dolly

Wow . . . . what can I say. Such precision and detail. Thanks so much for sharing. And now I only wish I would have taken Shop instead of Home Ec. back in the day. Would have been a lot more useful, even though I'm a girl. Well, a grown up girl. lol

Деревянный стимпанк :-) Всё ровненько, аккуратненько... Даже глазу нечему зацепиться. Но красиво!

Dude you are just so ingenious.. can I come over and watch sometime?

Could the sound reducing can possibly reduce the suction power by being slightly in the flow ?

I got your plans for this a while back, but the only motor I've got is a universal motor designed for 12800rpm. Is there any way I can slow it down, and if so, what rpm range do you estimate your induction motor is turning at? Cheers, and love the vids btw!

a lampada e uma boa ideia para ver o nível do por.

What CFM does this dust collector create? Your older version with the 1/3hp motor was 122 or about a shop vac. Just curious how this one ended up comparing.

Hi Matthias. Did it get better Dylos readings than your big dust collector with the bag? I really like your videos. Thank you so much!

nice design. i would be afraid of that bulb to melt the plastic bucket if it is an old fashioned bulb. I really love this project because it is almost entirely shop made. And it is smart.

When I had a nut that kept coming loose, I simply put a lock washer behind it. It has never come loose since then.

I see you put oil in your casters at 0:56 - I had to wash the oil/grease out of my casters after the oil picked up dust and bits.The casters started to steer where they wanted to, so when I pulled it about by the hose it refused to follow me! There is no serious load on the casters in the life of the unit, so they stay dry.

Did you think of using a cotter pin to fasten the arbor? Just drill a hole through the nut and arbor and set the pin.

Very cool setup, you should paint that plastic red trim ring the same green, and maybe the sound dampening can too. =)

i would recommend an led light bulb so you don't generate any heat

how do the filters look after using it? I had an impression the suction will be too high for such a small cyclone.

As always, I am entertained, and left wondering how I can make my wood-shop better.

I guess I missed where you got your motor from Matthias. Thanks for the video.

Hello Matthias. I can use a 500 watt motor in this project, will give the same suction? Thanks for posting all these videos.

So how does the suction compare to the larger Dust Collector now that you have all the baffles & filters on the system? Just curious if it is still better, thanks. Sincerely, Matthew

Does the air pass through (or by) the filters? If this can fit under an outfeed table, you have a million dollar design

That was pretty cool. What was the original intention of building this dust collector? Was it to replace the noisy on you created earlier that interfaced with your shop vac?

We tried something similar with a commercially built cyclone, it sucked the dust into a stout plastic bag supported on a wire cage, the bags kept popping in through the holes in the cage, So we replaced cage and bag with a heavy plastic dustbin (trash bin?). It scrunched up like a paper bag,:-(

did you ever need a flange for a motor, but you did not have any laying aroud, so you made one out of plywood? Do you have some expierience about that?

Do you know of any good explanations of the math behind filtration and pressure? I'm working on a similar project, but am having a hard time figuring that part out. I would like to come up with a formula for how many shop vac filters i would need, including whether or not i use the 3 layer fine dust ones, as well as when i should just move up to something larger.

Ok, I have to ask. Why *that* shade of green for all your stuff? Is there some story behind it? Did your dad buy a 50 gallon drum of it which never got used up or something?

Impressive machine. Thanks for sharing.

nice. A lot of work though. I like the ingenuity. bravo

I guess I'm a little late to the party, but would it have been a decent solution to simply drill a hole in the impeller shaft and use a cotter pin and a castle nut to keep the nut from spinning off the shaft?
