looking for help with dust collector

[reeftoker75]

I am looking for help or ideas for a dust collector . I am using the K2 router mount for a porter cable 892 router. Anyone have any ideas ,pictures, or suggestions let me know.

try http://www.wynnenv.com/ for filters and he has links to

I built a collector from bill Pentz's design using 2 garbage cans and some clear plastic.

See it in action here: http://www.youtube.com/v/5ar6-zpzeYE

The biggest hurdle will be the blower motor. But in my application, the pplaner had a strong enough one that I didn't need anything else. But I also have a 1HP mini-dust collector motor(no pic) that I can use as an intermediate. They are cheap enough for CNC since you wont be pulling big chunks through the squirrel cage.

On the other hand, if you aare going to the trouble, you might as well get a bigger motor/impeller drive and make it a whole shop collector and do it right.

I made shoe for my K2 kress mount. It slips on and off in seconds for easy toolk changing and works well. Should be easy to make for your mount as well.

I'm looking at setting up my own dust collector. I've got a 600cfm unit w/ a 3micron filter attached to it. I fired it up the other day and was suprised at how much pressure and flow in going through this thing!

My question is, how well does the dryer ducting work w/ a system like this? I'm having trouble getting my hands on the "real deal" dust collector hose.

I expect the dryer ducting will collapse and kink easier. But if I support it evenly will it do? I'd planned to zip tie it to the outside edge of my Echain and then mount the actual collector and bag on the back side of my gantry. It'd only have to suck through ~ 15-20 ft of hose then..


Curious..

Ok.. so moving along.. I've got my dust collector up and working. I did end up finding some dust collector hose and have been using that.. it all works pretty well.. but I plan to improve it w/ a cyclone [Al-la Bill Pentz] but above that I'd like to improve on it by adding a second filteration unit for the super small particles that will get past the cyclone.. I've a 3mo old son and don't want him being affected by my hobbies in the garage..

Has anyone ever experimented w/ water/wet seperators in the dust collection world? Any experiances anyone would like to share? I've got a few idea's but would like to hear what others have to say on the matter..

Thnks

Go ahead and experiment; I want to know how well it works. A few years ago I bought a big woodworking router and had thought about building a water curtain dust collector. I never did build the collector, things did not work out and I sold the machine after less than a year. But I have often wondered if the wet collection was feasible. One little bit of information I do have that could be pertinent (if correct) is that paper fibers suspended in water at greater than a 2% fiber content is starting to get to viscous to pump. If this is correct you may need a very large flow of water.

Have you ever thought about electrostatic collection?

Hey Geof..
I've wondered about E-static but don't know all the in's and out's [well don't know that about water either but it's easier to understand ] so figured I'd try water.. I'm thinking some form of a cyclone w/ multiple nozzles [windshield washer type from the local wreckers-- 5gpm would be great] shooting perp. into the in coming stream.. Lots of pressure and volume and then some form of a fiber filter to pull any airborne water back out of the air before it's discharged back into the shop.. The problem w/ all this is the whole thing gets rather large and cumbersome.. but I don't want to have any dust floating around.. my current bag unit is great for getting 100% of the larger stuff and alot less of the finer stuff.. I seem to be a bit suseptable to the dust as I get migrain's after running it for a day..

Not fun.. I'd rather NOT expose my son to it if at ALL possible..

I know of a fella who made a canister and 1/2 filled it w/ water.. he then hooked a shop vac to the top/lid and put the dust hose in the side.. inside the canister, the hose connected to a down spout which was perforated below the water level.. he claimed it worked like a hot dam.. but I've never seen it in action.. I don't think I could get the pressure I'd need to put the air through the water.. hence the need for some form of a spray system..

Waddiya think..??

Um, this is distinctly not good. I think right now you should check into some activated charcoal filter systems to take organic vapors out of the air. Formaldehyde vapors and other nasty stuff can be released from MDF.

Just some suggestions but you could always pump the dirty filtered air outside the garage, sorta like a dryer vent. You would need to enclose your filters into a box but that shoudnt be to hard and wouldnt take up much more room. Wind, Rain should do most of the clean up.


You will notice that even with all the filters and cyclone and pumping it outside you still get dust. This comes from what the dust collector cannot pick up or what gets away during cutting. So I would also suggest something like this http://www.leevalley.com/wood/page.a...t=1,42401&ap=1

Once the dust is in the air it's too late. If that filter is sucking in dust, then you're breathing it at the same time. The best option is to collect the dust at the source, which imo requires more than the 600cfm being talked about here. At least 1100-1200cfm.

What about a water filter like the drywall sanding system? Basically a bucket with a lid, attach a shopvac to one fitting (above the water line) and the sanding pad and hose to the other fitting (end of the line below the water line.

Vacuum in the bucket pulls the air thru the pad (has holes) down the hose and filters the air and dust thru the water.

I use it when finishing drywall for those never ending household projects and the filter on my little 2 gallon shop vac stays pretty clean (though depending on the amount of dust some makes it thru the water still dry as it balls up in water). Was thinking of adding some layers of screening to the water to break up the blobs before they hit the surface. But saw dust should not act the same as drywall compound dust.
