Dust Collector for a KMG???

Sounds good! I got my KMG wired up and mounted the motor yesterday, runs great! I am going to stop at Fastenal, they were able to get i think 60 grit belts in 2x72, i will continue to pursue and see if they can get them up to atleast 120 or 220, if they can get 400 OH MAN we are set, as long as they are not crap of course. i'll grab as many of the 60 grits i can afford and we'll try em out.

System looks good but i don't think you are going to get the vacuum at your grinder that you want or need, because of the open top container.
if you get yourself a large funnel and cut a hole in the top for that can and get the funnel up closer to the grinder it would work better.

Mike, how about raising the can a few inches? Better? Thanks.

it's not all about raising the can what you need to do is close off a lot of tha can so you can pull a vacuum.

my system is a lot like yours and what i did was put a top on that can and then cut a hole in the center of the top to fit the spout of this old large fuel funnel. the top of the funnel is only inches from the grinder.

with only this small hole in the top of the can you get about 10 times the vacuum at that point.

Just use 4' pvc. I've use it through steel, Ti, damascus, you name it, and it never catches fire etc.. I've had some burn spots, but nothing serious.. Plus, it's easy to manipulate with elbows etc... and replacement cost is next to nothing.

Then have it run out into some Hardy Board... (I'm not sure if that's the spelling, but it's cement board). I have that at the end of mine and it deflects sparks etc... into the water barrel.

Then again, I use a 50 gal barrel, buried in the ground with some water in it, so it's not really an issue. But I didn't always do it that way..........:)


I can shoot some pics of mine if you need some reference........

Mike, O.K., I got it, but it seems like the funnel is going to get in my way.
Thanks.

I've been using a sheet metal heat register as a collector under the KMG and it works pretty well I haven't noticed it getting in the way also I changed out the spark arrester that's in the picture to a 35 gal metal can similar to what you arre using.

I like it. Any fires?:confused: Thanks

I did have one small smoldering hole in the bottom bag of the dust collector but it had been used on wood before I got it and I guess I didn't clean it out well enough but since them no problems its also why I went to the larger spark arrester
 
Greetings,
I have been watching this thread for both metal and wood partial/dust collection ideas. The handle material settlement is everywhere in my shop after doing 4 handles from my 2x72" grinder. I would like a collection system which would be safe for both metal and wood collection (if one exists).

Please post pictures of your shop partial collection systems to aid in help the readers make the safest and best possible solution. Note: I know someone is going to post a picture of their shop vac and/or broom....I know it!

Regards, Dennis
 
Doing some research today...and picked up the necessary parts to build a cyclone filter in parallel to the dust collector. PLEASE ENSURE YOU RUN A BARE COPPER GROUND WIRE THROUGH THE DUCTWORK IF YOU ARE USING PLASTIC. There is a potential a fire can start if you have some wooden dust partials inside which could ignite as a result of the build up of static charge. I know that I sometimes get a static discharge when grinding for awhile.

Dennis
 
Thanks for posting the pictures, let me know if you would have done anything diffrent after you put it to work.
 
O.K., the cyclone chamber is collecting the fine particles into what looks like steel wool; nothing noticeable is collecting in the dust bags. I don't have a problem with this, as long as it collects somewhere.
Like a couple of the guys posted, I'm going to have to hook up some sort of funnel closer to the grinder....I'm still getting a lot of dust all over my workbench, and behind the small garbage can.

Install a air filtering system that hangs down from the ceiling, this will catch the duct that are floating in the air and reduce the steel dust that's gathering around in the shop. I have one as well. You can get one from Jet. You can purchase one probably in your town at some hardware store.

You will be surprise the first-time you clean it out and see all the steel dust that would have been in your shop and lungs. As far as health issued it will be one of the best decisions you will ever make.

Hope this was of help to you. And have a safe day out in the shop because it a jungle out there. :)
 
It there enough vacuum with a 1hp or 2hp to divert all the dust and sparks through water and not even need a bag to catch on fire? I would think so. There are some real advantages but may put some moisture in the air.

Thanks...that sounds like very sound advise, but I'm beyond broke at this point.

Bruce, I can't for the life of me think about how to make something like that.

Its simple enough. Are you old enough to remember the oil bath air cleaners that cars used in the fifties? All the air was drawn in and had to go through oil before it could go into the carburator. The oil caught all the dirt but the air got through clean. I think a large sealed bucket of water with the intake under water but the suction hose would be above the water. If the vacuum has enough suction to draw the dirty air through the water there would be no need for a bag. All the sparks would be extinguished immediately. The water would need to be changes but may be easy enough compared to emptying a dusty bag.
