I really like that you've included the trials and tribulations of building out what was formerly just an idea swimming around in your head. Human beings are creators and when you're working with something rigid like wood, metal, plastics, etc. they don't always cooperate, but again, it's our creativity that comes to our rescue. I enjoyed watching the honest process, I've been there and done that and I'd never trade it, thanks for this. It works.
Nice that you worked your way through a challenging problem with a very positive end result. You gave me lots of good ideas for my Dust Deputy system. Thanks!!
Maaan, you're awesome! You've opened my eyes on how to build cyclone stand. I wouldn't replicate yours, but you're definitely an inspiring person. Thank you, Sam! You've made my day!
I really like the idea of the sound baffle. I love how you showed us your design changes along the way and how you worked out the challenges. Great video 👍
Thanks so much! It's not perfect, and there's a 2nd video of changing/fixing somethings with it, and a third on the way. LOL But it's all part of the fun of testing and experimenting!
Thanks for this one Sam. I'm designing my own shop vac/dust deputy setup and have everything hashed out, but will be adding a simple cabinet with bottom exhaust baffle for the vac to my setup. I really like that idea and lower noise output. Keep it up. 🙂
Hi Sam, I put my cyclone and vacuum set up in another shed close to my workshop and brought the 2 1/2" pipe underground along with an airline for my compressor which is also in the shed. These PVC pipes only run about 7 feet long and a foot or so underground. Works great. I use a remote on/off power control and when working I just hang the small switch on my neck with a leather string. When the vacuum is running about all I hear is suction at the end of the hose. Same with the air compressor it is louder than my shop vacuum. Now, I need to make a vacuum and air run in my little shop, 16 x 16. Love my little shop now!
Lately I've been thinking of something along this line. Somehow you bring back one time doing something around my parents house. As I finished my mother said " It's OK to be dumb as long as you know how to help yourself." Well done!
Well this is timely for me... Dust collection is so much louder than the cnc. Finna watch the other two videos and let you save me some time AND money. Thx 🤙
Great video with lots of great tips I’ll use, I will be using automotive sound deadening matt and the hoses will get wrapped, so adding the muffler design!
growing up my father didn't educate me with tools and any type of "handyman" skills Seeing videos like this makes me so jealous, and people who did learn and use these types of skills (like op) likely think nothing of being able to build and create. Y'all keep the content comin', i'll sit back and enjoy watching.
Scraps for experiments. I like that kind of thinking. You're working out the bugs and overcoming issues. Neat ideas in that build. I may steal some of them...lol.
I totally agree, try something.. if it don’t work out try something else but keep moving forward.. it’s ok not to be perfect on the first try.. that’s where the phrase trial and error comes in.. Some UA-cam channels only show perfect success with the most expensive tools and materials.. I will subscribe..
I'm planning to make an enclosure for my shop vac. Your use of baffles inspired me - I have a spare motorcycle silencer (muffler as you would call it) from a 1960 Triumph 650. I'll incorporate that and see if it makes a significant difference to exhaust noise. But I expect that acoustic foam will have greater effect. It would have been interesting to see a decibel reading with the cabinet doors open, as well as when closed.
I love the video and appreciate the full and honest display of your process. Just a note on the variable motor controller; You will be increasing heat in the motor reducing its service life dramatically. A motor such as a shopvac is typically designed for one speed. In the US it is based on 120V 60hz. This variable speed controller most likely drops the voltage which means the motor sees less than optimal voltage. The result is higher current especially under high loads which means more heat than designed form. The additional heat means reduced service life and less torque available. In the electrical industry, we need use variable frequency drives to reduce motor speed which keeps the voltage amplitude the same but changes the frequency (48-60Hz) but they are expensive as it is not easy to do. Keep up the great work!
Thanks! There are two other videos on this system changing things -- the controller is one thing that is no longer in use. :) 🔗 Video #2: ua-cam.com/video/Sq1djLcSBLc/v-deo.html 🔗 Video #3: ua-cam.com/video/8VPfP9JIt0Q/v-deo.html
I really enjoyed watching you figure out what to do to make it work. I do that a lot myself. I have a small garage that I'm trying to make things work that shouldn't but ill try and sometimes it works but sometimes I just throw it away after cutting it or just simply destroyed it. 😂 😂 and dont tell the wife Lol keep it making films and videos you are good.
Be sure to check out videos #2 and 3# on this project. They'll probably help a lot seeing my improvements to the system overall. Maybe they'll save you some headaches that I had, too! :)
I have seen a handful of these over the past year, and still wonder if worth the time and material. I use my Harbor Freight shop vac/cyclone system that is mounted in the top corner of my 10x12 shed/workshop. But my thought is.... how much quieter will it be with the tool itself running as well. If the tool is loud will it matter if the shop vac is loud also?
Sharing your insight that a shop vac in a 1/2" plywood box is like putting it inside a guitar, I set aside some stained 2' x 4' acoustic ceiling tile to line the cabinet portion of a miter saw stand. It might work.
Great idea for sound reduction. I might build something similar for my air compressor. One thing to note, I have had many Rigid shop vacs over the years and the oldest one sounds like a jet engine. RIDICULOUS loudness. The newer versions are only about 78db, which is a HUGE reduction in noise. The 12-16 gallon versions can be had for about $100 on sale @HD, and have AWESOME airflow.
Good job! I made a box for my pancake compressor and was happy with the results. This will definitely be a good research video for people who want to clamp down on the noise! 👍
Very cool! Does the shop vac exhaust to the inside of the box directly, and the only exit is through the baffles? Or did you run a pipe from the exhaust port directly to the baffle chamber? It would also be cool to see a decibel reading with the front door wide open for comparison. Thank you for the ideas. 👍
Awesome work. Good attitude :) just get it done... Bitumen works better than open cell foam when you have large amounts of dust in the air, if you ever rebuild it. Budget bitumen can be made with asphalt paper (the thick stuff you put on roofs? Don't know the english name) that you glue to the surface with a non-hardening glue. Use silicone or non-hardening filler foam....
GREAT VIDEO. Suggest you soundproof the roof of the box and if possible, sound proof the roof, inside the dust collector (dry wall or some smooth foil backed insualtion material (like used in cars). There is gains to be made.
Just watched your vid on this shop vac enclosure. I made a roll around enclosed 2 stage system for my small shop too. For what its worth please consider this warning. Any enclosed system like this will generate quite a bit of heat. Your vac evidently has an issue that may cause it to generate more heat than it would if it ran normally. I bought one of those small rectangular vacs that auto detailers use. The one in my vac system is a Ridgid model but DeWalt makes a very similar unit. These are 5 gallon 5 hp units that pack a lot of CFM. Consider one of these in the future when you replace the one you're using now. These too generate heat but are very powerful and small.....much better than a larger clunky barrel type. My warning to you is don't let your enclosed 2 stage system run unattended for long periods of time i.e. while your CNC is doing its thing. This is a recipe for burning down your shop. Just sayin'
Fair point. You can also just leave the door open for extended run time. Additionally a 6 inch surface mounted fan inside the cabinet with a narrow slot on another edge will allow for some air exchange.
Hope you run your shop vac where your CNC spindle startup up so you only run the shop vac while cutting material and when done it turns off. I have a CNC setup like that, designed and developed my own PCB to be controlled by the software to turn on shop vac or any other device that needs to run while the spindle starts and stops.
Cool project, thx. One thing though: A normal, quiet room is around 30 to 34 db(A), depends on what time it is (day, night). A recording studio can reach down to 20 db(A). I think, your smartphone-app may be at least 10db(A) off. It would be interesting, what this app showed about the loudness of the vac without enclosure. Wouldn´t be surprised, if it showed something like 65-70 db(A) from aprox. 1 meter distance (avoiding hotspots in the room due to resonance). Anyway, reducing the sound from 65 db(A) down to 40 is a really good result.
Cool. I'd recommend ditching the angular foam. Use a combination of 1/4" open cell foam and 1/4" mass loaded vinyl. Float the mlv over the foam by securing with screws with a neoprene washer. Avoid compressing the mlv, and seam the edges with HH66 vinyl adhesive. Then, use insulated ducting, optionally enclosed in a snaking channel of plywood/mdf. Like a folded tapered horn in a loudspeaker. Keep the bends gradual to lessen the reduction to airflow. I'd bet you could get it to 30dB like that. Good work.
Thanks for these ideas! Pardon my ignorance - while I get using MLV for sound isolation, what’s the reasoning behind the layer of foam? (As I thought foam was more for acoustic treatment rather than isolation) And why have it underneath the MLV, as opposed to on top of it?
Hallo Sam, beautiful job !! I was so amazed that I built one for my little workshop too. The only thing I'm struggling with is that it do not suck air at the end of the aspiration hose. I checked all the line and all is correct. The question that came up in my mind is: How important is that the dust collecting bucket is perfectly adherent (tight) to the interior ceiling of the cabinet? I had the same cyclone system before but it was outside(not in a cabinet) and the dust bucket was a paint bucket with the lid cutted for the cyclone to fit. And all was fine. Bye from Italy and keep up the nice work! Ciao
For the system to work properly it has to be air tight from hose to vac. Any air leaks or imperfect seals in the system will lessen the effectiveness or make it not work. I have been tweaking this design a bit and there is another video on my channel about the changes. It is still a work in progress for me though.
@@Samcraftcom Thank you Sam, i watched your update video, and fixed also mine. The dust collector bin has to be very sealed to the ceiling of the box..... and I discovered a piece of plastic was stopping the suction. Now it works just fine. Thank you again.
What are the thoughts of spraying rubber coating inside everything to change the vibration potential. Thinking Flexseal type stuff would stick well help any bare wood from carrying vibration
Sam, nice design,maybe try some weather striping around the doors might cut down the sound even more. Also did piping the exhaust thru the floor on your first setup really help?
Instead of adding more baffling, you need to put some sound absorbers on the walls of the baffles you've got. Some cheap fabric store velvet or low pile carpet remnants or something that will absorb the sound instead of just reflecting it off the hard plywood surface.
hello, this is a very good video and great ideas. I wonder if you know if there is such a thing as a switch or adaptor that will switch on my vacuum cleaner whenever i start up a tool? I'd appreciate that. I am using an ordinary old vacuum cleaner, not a shop vac. thank you
Haven't gotten mine assembled yet as I'm still building my new shop ..but I plan on putting my system outside with a door to be able to empty the bucket into the chicken nest boxes or compost pile.
what about heat from the motor running for long periods when running with cnc? is that a concern? I've recently added a cnc to my shop and for a simple cheap route right now considering this vice extending my main dust collector across the shop.
Sometimes we have to use all of our available resources, there is nothing wrong with that not everyone can go out and buy pre engineered dust collection system. 40 DB that is great sound suppression for a shop vac.
Hey Sam, nice idea. I've built something similar for my CNC, and planned to add the router speed control to the shop vac (which is fully enclosed, w/ the HD "Duststopper). Have you found that dialing down the speed, not only reduces the db, but the heat generated as well? ('cause those suckers cook in an insulated enclosure). Thanks!
@@Samcraftcom Perhaps we have different setups. My shop vac and extractor are in a separate isolated enclosure (and my CNC sits above it in its own enclosure). The vac's outgoing hose blows through a sound baffle out the bottom, and the intake hose is fed up into the other enclosure to the CNC's dust boot. So, the speed of the vac won't change anything, as far as air movement, in its own enclosure. I haven't noticed a change in temp regardless of speed (it goes up considerably, but equally at high or low settings). I'm considering building a fan into the vac's enclosure, and then attaching a sound baffle surrounding the fan. Hoping that'll make a difference...
Hey dude. Great project and great video. Just watched the Dunn guy and he’s process is so dumb and useless. You actually accomplished something! And part of all of this is improving each single time. I wonder if using a ultra quiet motor from a compressor or similar would actually do something. I understand part of the noise is the actual suction of the air and the propellers themselves. I also wonder if using plywood for acoustics, speaker carpet and so would help. I recently saw a video of a euro dude making an encasement for his compressor (he ended up buying a ultra quiet one but still the box helped a lot) so wondering how much better this could be done (and if it’s even worth it) Great video man
Shop vacs use universal motors which can be easily controlled with a scr controller…. ($10-$20) just dial down that screaming motor speed as it’s overkill for 90% of usual applications .The sound will be improved immensely. For that 10% of time when you need the extra power, dial it up and get er done ;)
Yes, I had some heat issues. If you'll see the description for the playlist, I eventually add in a heat port that also keeps noise levels down. I think it's video #4 in the playlist.
G'day there. A very good video. I'm not sure though exactly where the air outlet is after the sound baffle. Is it that cut out corner on the back bottom? I love your concept and will try it out in my garage / workshop. Best regards. Mal
I ended up adding a dedicated exhaust baffle to this unit. There’s a video playlist in the description of this video that will take you to the others in the series. I made a few adjustments and reached a good point for my needs and uses. It’s been the same for a while since.

I like you style of presenting, its enjoyable.
Need to do this for my portable AC unit inside my house. 👍👍👍
Sam, nice video. When you get your CNC one of your first projects should be to cut a series of concentric circles and make a bowl for the vacuum hose.
VERY impressive, Sam! 40 dB?!?! You’re a miracle worker, dude!
Thanks Donny! I'm going to have to tweak the design (again), but that's part of the fun with such a Frankenstein machine anyway, huh? LOL
Damn good job!!!!!

Good stuff Sam.
Sounds like a great idea!
I've been very pleased with it so far! Some room for improvement, but mainly in the sealing up cracks department. :)

Great job man!! a big hello fom Italy 😃
Pretty darn impressive. The other tools will be louder. Pretty sure it’s as quiet as a Festool dust extractor. Well done!
Nice, thanks.
Nicely done. Fiberglass ceiling tiles are much more effective reducing sound levels. Fiberglass wall insulation is even better.
I’m looking to do something similar but to add Roxul Safe and Sound insulation inside the box. I have this insulation in my walls and love this stuff.
Excellent

Yeah... never would have done that with a new shop vac. :)
Seems good enough.

Don't know the english name) that you glue to the surface with a non-hardening glue. Use silicone or non-hardening filler foam....
Caulk the joints for air tightness, and apply heavy vinyl or butyl or drywall to keep more energy bouncing around inside the box.

what about heat from the motor running for long periods when running with cnc? is that a concern? I've recently added a cnc to my shop and for a simple cheap route right now considering this vice extending my main dust collector across the shop.
Sometimes we have to use all of our available resources, there is nothing wrong with that not everyone can go out and buy pre engineered dust collection system.
40 DB that is great sound suppression for a shop vac.
Much appreciated! :) I was really surprised at the 40 dB too
Hey Sam, nice idea. I've built something similar for my CNC, and planned to add the router speed control to the shop vac (which is fully enclosed, w/ the HD "Duststopper). Have you found that dialing down the speed, not only reduces the db, but the heat generated as well? ('cause those suckers cook in an insulated enclosure). Thanks!
I've since removed the speed controller. I found the slower speed did help with noise, but it made it heat up more from the slower air movement.
@@Samcraftcom Perhaps we have different setups. My shop vac and extractor are in a separate isolated enclosure (and my CNC sits above it in its own enclosure). The vac's outgoing hose blows through a sound baffle out the bottom, and the intake hose is fed up into the other enclosure to the CNC's dust boot. So, the speed of the vac won't change anything, as far as air movement, in its own enclosure. I haven't noticed a change in temp regardless of speed (it goes up considerably, but equally at high or low settings). I'm considering building a fan into the vac's enclosure, and then attaching a sound baffle surrounding the fan. Hoping that'll make a difference...
Any issues with heat? I like the speed controller idea.
Hey dude. Great project and great video.
Just watched the Dunn guy and he’s process is so dumb and useless. You actually accomplished something! And part of all of this is improving each single time.
I wonder if using a ultra quiet motor from a compressor or similar would actually do something. I understand part of the noise is the actual suction of the air and the propellers themselves.
I also wonder if using plywood for acoustics, speaker carpet and so would help.
I recently saw a video of a euro dude making an encasement for his compressor (he ended up buying a ultra quiet one but still the box helped a lot) so wondering how much better this could be done (and if it’s even worth it)
Great video man
Shop vacs use universal motors which can be easily controlled with a scr controller…. ($10-$20) just dial down that screaming motor speed as it’s overkill for 90% of usual applications .The sound will be improved immensely. For that 10% of time when you need the extra power, dial it up and get er done ;)
Great video. Did that remote switch actually work with vac? Thought the wattage would be too great.
Yeah, they do great! Have used them for about 2 years now without issues.
I just built one of these. Thank you for the great ideas. Q: My shop vac gets pretty hot in this box, are you having that experience?
Yes, I had some heat issues. If you'll see the description for the playlist, I eventually add in a heat port that also keeps noise levels down. I think it's video #4 in the playlist.
What’s the CFM with all those baffles?
G'day there. A very good video. I'm not sure though exactly where the air outlet is after the sound baffle. Is it that cut out corner on the back bottom? I love your concept and will try it out in my garage / workshop. Best regards. Mal
I ended up adding a dedicated exhaust baffle to this unit. There’s a video playlist in the description of this video that will take you to the others in the series. I made a few adjustments and reached a good point for my needs and uses. It’s been the same for a while since.
