Instructables
Picture of DIY Dust Collection System
While making my Promethian Fire Egg I needed to make a divet in some concrete. I briefly considered using my Dremel for this, but I decided it would kick up too much dust and make a mess of the shop. It was then I hit upon this idea. In doing a quick search of Instructables I found Rachel had made a passive dust collection system very similar to my idea. My system incorporates a Shop-Vac to actively draw in the dust, instead of only containing it. (And I just saw that someone had suggested adding a vacuum attachment and the plexiglass top piece incorporated into my project. So now I look like a thief. Crap!) Aside from containing dust there is the added benefit of not having to use as much safety gear. The box will contain the dust and flying debris so I won't have to wear a dust mask or safety goggles.

If you build a passive version of this project you want it to be air-tight so that dust won't escape. If you build an active system you need the unit to allow air to flow in so your vacuum can work. Lack of incoming air could damage the motor of your vacuum.

You can allow for air flow in one of two ways:

1) You can build a specialized opening that allows air to enter while the rest of the unit is air-tight. This would allow you to also use the system in a passive mode if your vacuum was unavailable.

2) You could allow spaces around the various penetrations into the system. This would allow air to flow in along multiple paths and requires no specialized openings. The downside being that it would be messy to use it in a passive mode as dust would be more likely to escape. I went with this method as I am a sloppy cutter.

A note: I'm entering this in the Craftsman contest so there will be blatant ass-kissing shots of the Craftsman tools I used for this project. Product placement will probably not sway the judges, but it can't hurt. :)

Idea to cut down on shop vac filter replacements. Get a 5 gal pail, but 2 holes in top (on opposite sides) . One hose will will fit shop vac hose tightly (its end stays at the top of pail). This hose is the vacume from the vac. On the other hole run a duplicate vac hose from your enclosure into pail, going all the way to the bottom of the pail. Fill the pail 1/3 with water. Turn on vac....
Now as dirt/dust passes though the water on its way to the shop vac, it will get deposited into the water. So a lot less dirt/dust gets passed onto the vac. Just empty the dirty water, and you'll have to replace shop vac filters a lot less.
I've used this when sanding dry wall, to keep the fine dust contained.

Cool idea. I'll have to try it once the weather warms up.

Good job! Another use for this might be a soldering isolation station or a mini paint spray booth. Just vent the fumes out of your garage or window using the vacuum or a duct with in-line fan. with the replaceable plexiglass lid you don't have to be too concerned about overspray or wear.
Tack122 OCLVig2 years ago
You could make the plexiglass last longer with some plastic wrap covering it too.
This is REALLY cool. I bet with a little bit of modification one could make an inert atmosphere work chamber. I'm not sure what sorts of hobbies require working in a completely inert atmosphere (and I'm a chemist!), but hey, it's good to know that it could be done if necessary ;-) Maybe using thicker plastic I could make a blast-proof box. I'd still be concerned about my fingers, however.
RadBear (author)  DeusXMachina5 years ago
The only hobbies I can think of that would require an inert atmosphere are probably illegal. :) It would be an interesting challenge though. For blast proof you'd probably want to use something heftier than plastic like steel reinforced concrete or just steel. And to save your fingers you could invest in those cool robotic arms. But at that point you have entered the realm of government spending. So I suggest plan B where you offer a stupid co-worker whom you don't like free beer if he mixes the dangerous compound or welds some metal in a hydrogen rich atmosphere. It may not be nice, but you'd still have all your fingers. :)

Well, according to this WikiPedia article bulletproof glass is actually a sandwich of plastics and glass. So if you really needed the chamber itself to be blast resistant, you could probably attach additional layers of plastic to the outside surface of the box. Or at least surround it with several sheets of plastic and tempered glass, possibly in a modified version of your "picture frame" top cover. That way the shattering of the glass will absorb a lot of the energy and the plastic layers will allow the sides of the unit to flex, preventing unfortunate glass shrapnel.

As for protecting your hands, make yourself some [http://en.wikipedia.org/wiki/Gauntlet_(glove) gauntlets (Wikipedia)]. All you really need are some good work gloves with some steel formed to fit around your hands. Attach the steel to the gloves via rivets, and you're good to go. (Sort of a steel toed boot for your hands. On steroids.) And there's always those "cut resistant gloves" that are marketed to home cooks. Those might offer another good starting point.

Just a few thoughts for you.
RadBear (author)  mbear5 years ago
The guantlets would leave your fingers vulnerable, and they could become shrapnel if there were an explosion. Plus they would be heavy, so you might want to go with something made of carbon fiber or kevlar. But since I'm too cute to be armless and or impaled I'll let someone else build and test the blast proof cabinet.

DIY-GUY replied:
Not all things are bad. Certain jobs just need a cleaner environment.

Some delicate metalworking may benefit from inert atmosphere, and any time an oxidizable metal is cleaned prior to electroplating; you would really want to avoid forming a micro layer of rust.

Just my $.02 worth in relation to legitimate hobby use of an inert gas clean box.
RadBear (author)  DIY-Guy2 years ago
I stand corrected.
DIY-Guy RadBear2 years ago
You're a good bear Rad-Bear.  :)
(Now where are those pik-i-nik baskets!?)
What about fireworks? Wouldn't assembling those shells benefit from an inert atmosphere? Of course you'd probably still have to be concerned with static electricity throwing off sparks, but that could be overcome.
The bigger threat would be the static electricity. The inert atmosphere wouldn't help if your blackpowder caught because it's self-oxidizing. Maybe if you found a way to circulate anti-static gas.

I'd love to build thing, but chances are I wouldnt use it much and it would just sit there collecting dust.

Great idea! My wife always nags me when I use my Dremel because of the dust (mostly wood). I wonder if the gloves might be over kill? If you have the vacuum attached opposite your glove openings the vacuum should pull the air through the spaces between your arms and the openings and out the back. Just a thought.
Also if your working on something that that you don't want on your skin, like fiberglass...the gloves are a nice touch. I got a couple of strands in my thumb and index finger the other day and I know that it will be hurting for the next few weeks every time I touch it
I know I am almost 3 years late. But it sounds like you are describing what my GF
says. She claims that she can see metal particles flying on the air, even a week later!! I just had to agree with your commentaries.
AH...You have been watching the Red Green Show on PBS. You have learned how to keep peace at home by following Red's advice and saying, "yes...dear"
RadBear (author)  flaco15 years ago
The gloves may be a bit of overkill, but they keep any dust that may settle on your hands from escaping when you pull your hands out.
flaco1 RadBear5 years ago
Duh! I didn't think of that.... back to my FIRST statement, GREAT IDEA!

That is verry cool; and YES I coulda' used that for my sewing machine mod.
... as much as I end up dinging my hands with the Dremmel... I wonder how often I'd be replacing the gloves. Your shop looks like it is well lit, I think in my studio I'd put some sort of light in or directly over the thing.
RadBear (author)  zomfibame4 years ago
The great thing is the gloves are cheap so you can replace them easily. You can find them at the dollar store. Also they might provide some protection so the cuts aren't as bad. But I'd suggest working on keeping awareness of yourself in relation to the Demel. It sucks to have a nick name like "Stumpy".

I've also started using a deadman foot switch on my Dremel. That way if anything goes wrong I just lift my foot and it stops. Very handy (footy?) when I lost control of the Dremel flex shaft one day.
very cool might make!

Very cool, i ve builded something similar to operate the broken hard disks....i used more thiner gloves of 1 use (latex). Also i appied some extra antibacterial filters and the hood is ready
RadBear (author)  agis684 years ago
Why anti-bacterial filters?
agis68 RadBear4 years ago
because also in this closed area some bacteria can develop and also some fungus so you will need antibacterial filter...(low cost) There in any size in the market, i suggest them for car air conditioning system (10 to 30 $)

just flip the glove inside out!
RadBear (author)  Sandisk1duo5 years ago
Ummm...to what are you referring? Do you mean as a way of putting the glove on the glove mounts?
yes
RadBear (author)  Sandisk1duo5 years ago
Cool.
mbear5 years ago
This is really well thought out. And I'm sure it would serve another purpose as a paint booth. If you've ever painted miniatures or models with the harsh chemical paints, you know how much they stink. Something like this would take care of the fumes nicely.

Great job! I could really use something like this. 5/5
RadBear (author)  LinuxH4x0r5 years ago
Thanks! I haven't tried it out extensively yet, but I think it will be useful.

Good idea. I should have an apparatus thus.

Awesome Product placement, not too intrusive, but still clear and to the point... Oh yeah, great project too.
