Dust Control
« on: January 13, 2013, 09:48:00 PM »
I hate joining a forum on a new hobby or craft and soaking up all sorts of knowledge and having nothing to give.  I’d like to give back best I can with a topic that might be of help to the craftsmen here; dust control.

If you’re like me, your money goes towards tools that help you make things as you can afford it.  In a wood shop, a lot of these tools generate dust and lots of it.  Dust control now becomes an item that you want to get a handle on, but dust collection tools can cost even more than the tools you’ve already bought, especially if you begin to go by the old adage of “you get what you pay for”.  I don’t have handy pictures for the size limits of this forum, so you’ll have to excuse the links to my FB page.

Dust Collection
First thing I tried was hooking up my trusty dusty Craftsman shop-vac to the tools I was using.  That works pretty good for about 5-10 minutes; the filter gets clogged up and the system quits moving air.  Air movement is what clears dust.

So I got online and found this device called a Dust Deputy.  It‘s a cone shaped device that uses a vortex action to suck sawdust down into a 5 gallon bucket before it can go into your shop-vac.  Pretty cool idea and lots of testimonials.  I was about to pull the trigger on this when I thought that I could make my own and be using it before the day was done.  I bought three different sized plastic round planters, made my own vortex shape and had it dumping into a five gallon bucket.  And it worked.    Mark 1  

But having a tippy 5 gallon bucket in between the shop-vac and whatever I was working on meant lots of start and stop interruptions because the bucket had fallen over.  I then made a little cart for the bucket and secured it to the shop-vac with bungees.    Mark II    Better, but still had one major problem; static electricity that really got my attention.  I don’t know how many times before I tazed myself before I finally figured out that I’d either have to get the wife to start emptying the bucket for me or find a better solution.  Coupled with the fact that I can fill a 5 gallon bucket with sawdust in just an hour told me the solution needed to happen sooner rather than later.

So I was in the hardware store one afternoon and they had these metal 35 gallon trashcans for sale for like $15.  Light goes off.  I buy one, bring it home, re-enforce the lid with 1/2” plywood, cut two holes in the top, and attach the plumbing from the Mark 1 version, and find out it works just fine without any fancy vortex action going on.  I can now collect about 17-18 gallons of sawdust before I have to empty the can.  Further, I find that I can move to the fine dust filter for my shop vac (not the HEPA) and still move sufficient air to make it work.    Mark III  

Air Cleaning
Next problem I encountered was that no matter how well I was collecting dust, it still ends up coating everything in the shop.  The dust collector was keeping big piles from forming up on the floor with the major cutting tools, but sanding was creating too much fine dust and making it airborne.  

I found an old swamp cooler that had seen better days.  It was a window unit (big one too) that had a relatively new motor, perfect looking squirrel cage and decent looking front grill where the air comes out.  I pulled these items off the frame and built a new frame on wheels around it.  I finished everything up with a box of oak laminate flooring I had bought for $2 at a garage sale.  I setup two sets of grooves to accept two different types of filters, one course for big stuff and one fine for dust.  This contraption can move some serious air.  I see a considerable difference if I do all my sanding in front of the intake of this and I also have a new surface to work on that is considerably higher than workbenches.    Air Cleaner Exposed  

Sanding Dust Collection
My latest device is simply a box that has pegboard on the top with a hole in the bottom that allows me to put my dust collection hose into.  I can now hand-sand, Dremel-sand, or use any other hand tool that doesn’t accept a hose for dust collection.    Sanding box  

Not bad for a bunch of items that cost well south of $100.  Are they better than the stuff you'd get from Jet or Grizzly?  Nope.  But until I have enough disposable income to buy these things from Jet or Grizzly, they work great!

Hope this helps out!

Could you do a build along?  Sure would like to see the components being made?

These are some great ideas! Thank you for sharing, I WILL be making a small pegboard box like that!  Great Job!  :thumbsup:

Stringstretcher, I didn't take a lot of pictures while I was building these, but I'll see what I can throw together.  

BTW, if this is not an appropriate topic for this forum, please let me know; don't want to be getting any feathers ruffled!

Dang Brian! Forget about you coming down to ABQ, you may laugh at my shop. I may have to make the trip up there to "inspect"

Hey Ralph, the only shop I'd laugh at is the one that's not getting used!  If I could even begin to approach the craftsmanship my grandfather and father obtained from their modest shops I'd be very happy  ;)

You're welcome to come by anytime you're in the area!

That's great. I bought a 2 stage dust collector a few years ago but since I have moved it sits in the corner collecting all the dust it should be sucking up. Think I will pull it out and put it to work again.
And I think this is the perfect place for a thread like this. We all make dust while building bows so it fits nicely here.

Yeah I like the look of that dust collector. You'll have to take some pictures for us and show us the inside of this thing so we can get an idea of how it works.

I currently use 2 rigid shop-vacs with drywall filter bags.1 for the bandsaw or both on my sander. I'll bet with your engineering I could stuff the two in a corner and create a piping system to each tool and possibly on the work bench. More pics would be great. Thanks Brian

Looks good McCool.  I bought a Jet dust collector a few years ago when I had a dedicated shop before I moved to this place.  I added the garbage can separator in front of it and it worked great.  I had PVC duct work to all my stationary tools and added a floor sweep. I built a similar air cleaner and sanding box with the same success.

For the static electricity problems (which can be dangerous, meaning explosions) I ran a grounding wire through the system.  I have a book around here somewhere that shows how to run the grounding system.  

I found building all those "accessories" and shop jigs were just as much fun as building the furniture I used to make.   :)

i run copper wire from a good ground on the dust extractor, through , inside the ducting, exiting the pipe just before the machineout of a tiny drilled hole, then attaching to that machine with a good ground connection. and at 'T's and 'Y's i exit the wires just before the joint and connect them all together, so that there is only one strand of wire per pipe.
i bought the kits fromlee valley tools, cheap, and with good instructions.

I was about to go with the copper wire gound before I bought the metal trash can.  Once I've been using that, I haven't had a problem with static discharge.  I still haven't hooked up a ROS to it directly yet, but that's why I have the sanding table now so I haven't bothered.  

Maybe I put too much faith in them, but I saw what the Mythbusters had to do to get a sawdust explosion, and I'm pretty sure I'm not replicating those conditions in my shop  ;)

When I researched the dust collection set up I found guys talking about the possibilities of explosions and those that said it wouldn't happen.  I followed the safe route and grounded my stuff.  I took a year of physics in college and decided it was easier to ground than to figure out the possibilities.  LOL  College was a looooong time ago too!   :)
