10 Top Tips for Dust Collection

Trach can with fence

Good fence makes a better cyclone collector

After adding a garbage-can chip separator to my dust-collection system, I decided it would be easier to take the chips to the curb if I put a trash-can liner in the can. Oops! The first time I turned on the collector, it sucked the liner into the hose, rendering the system useless.

To remedy this situation, I fashioned a sleeve out of 2x4" welded fencing that fits inside the trash-can liner. I made mine an inch or so smaller in diameter than the bottom of the can to keep from damaging the liner as I insert the sleeve. When it comes time to empty the can, I lift out the sleeve, wiggling it from side to side. Then, I just pull out the bag, tie it up, and take it to the curb.

If you pull a black garbage bag over the top of the can to the ground, and then invert both the can and bag, you can lift the can out with a minimum of dust in the air and no liner needed. I also compost the sawdust, mixed with horse manure because the sawdust needs nitrogen to decompose quicker.

You can also use a length of cardboard tubing that is used for casting concrete piers. Smaller tubes work with the Dust Deputy. JimQ

I considered a cyclone lid as an addition to my Delta 1 1/2H collector but after reading reviews I'm inclined to skip it. Instead I welded a bracket that bolts to the wall to support the ring the upper and lower bags mount to so that I could eliminate the support legs. Now the system is free standing, with nothing in the way. I use a plastic trash can to support the bag below and I also use Husky brand 42 gallon contractor bags - much cheaper.

regarding the collapsing of your trash can. do a search on the thien dust separator. this is a baffle assembly that fits on top of the can like a lid and limits the high velocity air movement to the top 3" of the can. the chips and dust go down into the can where the air movement is very limited. i built one and it really works ! it also keeps your exhaust filter cleaner.

I used some scrap formica to make a liner to hold a 30 gal garbage bag in my shop vac. When it is full the liner slides right out the top without pulling sawdust with it.

I've worked on the sleeve idea to hold the garbage bag and finnally used cardboard to make the sleeve. Taped ends together to make the cone and don't have to worry about bag punctures.

Rockler has a Dust Collection Separator that fits the metal garbage can with 4" connections molded into the plastic top. Looks like it is molded such as to help a cyclone type circulation in the can.

I got a fiber 55-gal drums used to ship grains and sauces, much more crush-resistant than garbage cans. Full of shavings and sawdust, it weighs about 80 lbs, not an unmanageable load.

response to kish677: I found that you can make a flange that fits 4" air hoses almost perfectly, using one of those small cans that the specialty coffees come in (take off the two ends, go to work with tin snips). By splaying 1" tabs cut in one end and cutting a tight-fitting hole, you can make a pretty good joint, if you use silicon caulk on the outside to seal it.

I made a seperater using a metal garbage can hooked to my shop vac. Problem: the force sucks the can in like a light weight beer can. Do you think the wire cage would help?

I have a long uphill driveway, so in the winter when there is ice, all the captured sawdust comes in very handy for traction.

Great idea! This idea can be used for those of us who bag their grass, then have to transfer it to a liner and recycle it. Thanks
