I had been planning on putting in a dust collection unit for the last several years and slowly planning it. I bought the Harbor Freight 2 HP dust collector a few months back and tried out the motor to make sure it worked then put it back in the box while I planned the rest of the system. I didn’t want to give up any valuable floor space to a rolling dust collector so I knew i wasn’t going to use it on the cart that it comes with. Finally got around to modifying it and putting the motor and filter in the garage loft.

I still used the middle metal can from the HF system, but I mounted it on it’s side on a piece of MDF. First I routed a big circle and put some weather stripping in the recess to make a good seal and used some window latches to snap it to the MDF. These work pretty well because they pull the can on tight as you latch each of them and so it makes a nice tight seal.
Purchased an Oneida Dust Deputy to separate the dust before it gets to the motor, seems to work pretty well, I can’t feel anything in the filter bag yet.
Stuck with the 5 micron filter bag that came with it, eventually I’ll upgrade to an aftermarket 1 micron filter.
Piped the whole garage with 4” PVC and blast gates over the last two weeks and got the whole system hooked up last night. It works awesome, I’m really excited to start using it. I need to get a remote control to turn it on and off still.

Also still looking for a better way to lift the 55 gallon drum up to the lid so that it’s not hanging off the whole system. Right now I have to shim it up to get it up to the lid then latch the lid on. It’s a huge pain in the ass. I’m thinking of getting some kind of bar stool screw that I can turn and lift the can slowly with. Any ideas?

Now that is really using what space you have. I have thought about getting a Dust Deputy as well. Which one did you purchase to use and your drum?

could you vent the fine dust thru the ceiling roof out into the outside world? i could see doing this to my 3HP grizzly.
i saw somewhere (here or else where) that someone used something that looked like a upside down oversized can crushing lever assembly to raise and lower a bucket or drum a couple inches.

has to be the “super” version, as my newly arrived standard dust deputy is white plastic formed and 12-15” tall.

I have never seen one of these sys turned sideways. Thinking outside the box.

I would remove the cyclone from the drum and attach it to the wall as it looks like you are close. I would then set the drum on the floor and put a flex hose between them making it simple to remove drum lid. JMHO.

just noticed you are using a metal 55gallon can with removable lid.
i 55gallon plastic blue barrel with no removable lid fell into my lap over the weekend. i have to figure out how to either do a super dust deputy like you have tried, or put in a Thein baffle… when the lid is not removable. maybe with the Thein, i have to cut off the entire top anyways.

Is that a window latch holding the filter can on? Good idea, I’ll remember that one.

Holbs what I did was cut the inside of the top out of a plastic drum and leave the top lip. I then cut a groove in a piece of 3/4” plywood circle and added a strip of weatherstripping to aid in sealing. I then installed the Rockler separator kit in it and rigged up a clamp sys and clamped it to the drum. You can see most of what I did here. It is hooked to my HF DC.

ah. that is what i was thinking i would have to do. cut off the top portion but leave a lip. 1”? 4”? something to consider when it comes time to empty the barrel out and also whatever attachment i have in mind.
i have time to figure it out. for now, small dust deputy and shop vac :)
