20 reviews of this product found across Reddit:
- Layers of OSB with greenglue, carpet adhesive or contact cement between work very well.
- block as many air gaps as possible
- at some point, consider switching to a spindle (ideally water cooled as you will likely get a lot of heat build up). It will be much quieter and more powerful
- Rubber feet under the machine/entire enclosure (similar to the rubber pads you can get for washing machines).
- windows will be a liability, double pane will work better than single pane.
The next problem to address is dust collection. As you have probably found, the vacuum will likely be the loudest thing in your shop. You could help mitigate this by building a similar box around that too, but you would need to watch to make sure the vacuum doesn’t overheat as it uses air for cooling. I don’t know if you have one somewhere but a cyclone separator is a great addition to your dust collection and will significantly prolong the life of your vacuum.
Nice setup, you seem to be approaching it the right way. Nice idea to keep a fire extinguisher handy, it’s so easily to have something go wrong and it’s good to have a plan B.

It’s not even $10 more, just doesn’t come with the pre-drilled lid for the bucket.
Either way, I’ve found that 1/4” plywood attached to the lid adds a ton of rigidity for attaching the cyclone.
so unfortunately the only person i know who actually claims nm-sizes is the guy from that one ebay selling silver
i assume the only reason this silver dust is manufactured in the first place is for holographics (the reason i bought it, is to try to make my own holographic emulsion with gelatin) so it may not be common for other materials. because most powders have a distribution for particle sizes, it is possible that you may be able to separate the smaller ones yourself using something like a cyclonic dust filter - im not sure tho (eg, separating by density using centrifugal force just like in nuclear refineries). if you succeeded in doing that you could start a business :)
i think i searched for "nano powder" or "nm powder" something to that effect.
Cyclonic dust collectors are very much worth the trouble. They save you an enormous amount of headache, and keep your vacuum's suction high enough to carry away the chips you're making.
The one you linked looks like it would trap medium sized particles pretty well, but with mostly straight sides, and the funnel down at the bottom, the vortex might not get going fast enough to spin smaller particles (like MDF fines) out of the airstream.
If you're not married to the idea of DIY, the Dust Deputy is an awesome option which works very well to clean your airstream.
Good Luck!
If you're going to sand indoors, use a sander that has a vacuum port along with a shop vac or other vac, and most importantly a dust deputy and a 5-gallon bucket. The Dust Deputy is a cyclonic separator, it gets 99% of the particles out of the air before the air goes to your vacuum and the remainder go in the filter there.
You can build a simple collection system using a shop vac, a cyclone, and a bucket. This cyclone works well for me: http://www.amazon.com/gp/product/B002JP315K/ref=pd_lpo_sbs_dp_ss_1?pf_rd_p=1944687462&pf_rd_s=lpo-top-stripe-1&pf_rd_t=201&pf_rd_i=B00079UPSQ&pf_rd_m=ATVPDKIKX0DER&pf_rd_r=0R6HMSXQ1VQGG8BMV17M
Vacuum cleaners by their very nature deal with flammable dust ALL THE TIME otherwise you would hear far more stories of vacuum cleaners being used in homes and shops blowing up, and that just isn't the case. Movie physics is not real life.
​
Vacuuming powder is not a problem for the majority of modern every day vacuum cleaners (I say majority because someone is going to dig up an example of something with a very specific set of circumstances that happened once and point to that like it happens frequently. And no vacuuming gasoline vapors does not count. Seriously if you do that you deserve what is coming). My hobby room is a second bedroom with carpet and this is how I have handled powder spills no problem. The only way you *MIGHT* have problem is if you have an older direct contact impeller style upright vacuum like a Kirby and I say that very carefully. I think it would be difficult to maintain any kind of fire due to the turbulence of the air. I don't know if you have ever tried to light a fire in a turbine but it takes a very controlled set of factors to get that candle lit.
​
What people fail to realize is that most dust in suspension (mixed with air not resting on a surface) is highly flammable. If that is sawdust, flour / grain dust. You get some in the air mix it with a flame and you will have a rapid ignition, if you have enough of it then it turns into an explosion.
​
I work in a manufacturing plant and we use standard off the shelf consumer vacuum cleaners to tidy up our workstations we deal with flammable dust and have never had a problem. We even had a bearing seize up in a vacuum, the motor overheated and caught on fire and still no explosion. We have vacuumed tons of dust this way. I think people are conflating movie physics with real life. In real life if a car catches on fire it doesn't actually explode unless its laced with explosives and tanks of petroleum.
​
Most modern vacuums put the impeller, motor and everything downstream of the canister, bag, or water (if you are into rainbow vacuum cleaners). Besides that you would have to have exposure to a spark or open flame and the correct stochiometric balance to create fire, let alone an explosion. Only a small portion of dust makes it out of the collection device (bag or whatever) and that tiny amount is hardly enough to create an explosion.
​
If you are worried about this in the future, get yourself one of those sawdust cyclone attachments that they sell for home shops. All your heavy reloading powder will get trapped in that and never make it to your vacuum cleaner. https://www.amazon.com/Oneida-Molded-Dust-Deputy-Cyclone/dp/B002JP315K
I had to do a double take to check that I didn't post this last night without remembering.
I am going through this same process with the 10x14 attic space above our bedroom. I started off with Plan B and tried a few different methods. Filter bags filled up much too quickly and would have been expensive but they did a great job of containing the mess. I have a Dust Deputy attached to my vacuum which helped, but inevitably, the shopvac would get clogged with insulation that made it out of the vortex. My most recent adaptation was to attach the dust deputy to the top of a 40 gallon airtight drum I bought from amazon and then use some old pantyhose around the shopvac filter. This greatly extends my times between either emptying the shopvac or emptying the 40 gallon barrel. Inevitably the shopvac gets filled first but the pantyhose does a great job of keeping the filter in usable shape.
I did buy a Toro leaf blower/vacuum and it worked well but I didn't have an airtight container at the time so the fine insulation would just blow out from under the lid of the trash can I was using. If you have ANY holes in the tubing, you will have a dusty mess on your hands. I plan on retrying this method on the remainder of my attic in the next couple of weeks. If/when it doesn't work adequately, I will buy some insulation bags from Amazon and that should finish the job for me.
I'm not going to try this(or I might) but I think if you daisy chained two dust deputies and two drums, you would be absolutely fine with a shopvac.
I also made the mistake of failing to consider the difficult in mixing the Green Fiber cellulose bales without their machine once I had removed the old insulation. I only needed 7 bags for above our bedroom but man was that a PITA. I used a concrete mixer attached to my battery powered drill and managed to get in a great rhythm but having the machine would have been a million times easier.
Great post! I just checked out a video with a version of this sander that has a pole attachment and the guy shows some better perforated drywall sandpaper that he recommends vs that mesh stuff: https://youtu.be/YGDl3frdkD0
Here’s a decent looking dust separator: The Dust Deputy DIY Standalone Anti-Static Cyclone Separator (The Dust Deputy DIY) https://www.amazon.com/dp/B002JP315K/ref=cm_sw_r_cp_api_i_v5doFbQAAFGBH
Seriously though, if you had a "Dust Deputy" sort of setup, would that work for this situation?
this is what my system looks like
Sorry if it’s confusing but I’ll link some of the items in the diagram
For the 4 way intersection just connect two 3 ways
I don’t reccomend those items necessarily you’ll wanna look for them based on your hose size.
btw you’ll wanna buy a shit load of shop vac hosethis clear hose is a bit less user friendly (compared to the hose that comes with the shop vac) but it a lot more cost friendly.
Dust Deputy on a 5 gallon bucket paired with a Shop Vac or a Cheap dust collector
I’m looking at ordering this. Just need a shop vac and a 5 gallon pail, and you have a dust collection system.
Cyclone dust separator - stop your shopvac from exploding
Here's mine (3d print is being shipped):
https://www.thingiverse.com/thing:3015319
It will be coupled with this dust separator:
https://www.amazon.com/gp/product/B002JP315K/ref=oh_aui_detailpage_o01_s00?ie=UTF8&psc=1
I'll make a quick youtube once I get it working.
Have you seen these?:
Amazon sells the cyclone alone for about $50.
But I've seen some DIY options that cost just around $20, like this dude's: https://www.youtube.com/watch?v=GqGtyCthVQs
On top of a bucket with a tight sealed lid, and hooked up to:
The cyclone separates the bulk of the dust/debris and drops it into the bucket below so it doesn't wind up in your shop vac, which extends longevity of the vac as well as makes the time between emptying much longer since it's now the size of hte bucket not the tiny little vacuum.
Of course you could always make the blower yourself too but it'll be hard to beat a shop vac in price efficiency.
I just started using it this morning so it's a little early to tell how everything is going to work.
It's this cyclone [(http://www.amazon.com/gp/product/B002JP315K?keywords=dust%20cyclone&qid=1448213927&ref_=sr_1_1&sr=8-1)] attached to this drum [http://www.amazon.com/Eagle-1610MB-Polyethylene-Lever-lock-Capacity/dp/B0026GO5CA/ref=pd_sim_469_19?ie=UTF8&dpID=31in2c1J8uL&dpSrc=sims&preST=_AC_UL160_SR160%2C160_&refRID=11X61V0B9JJX3X88YBG9].
The 2 1/2" Shop Vac hose goes from the vacuum to the cyclone and another hose goes from the cyclone to the table saw, belt sander, etc... I'm hoping that it will save me from having to clean my vacuum filter as frequently as I am now.
