I got the idea from mreza (mini-cyclone shopvac modification). The main differences are that I chose to buy a dust deputy cyclone instead of making my own and I stacked the vacuum chamber directly over the cyclone. It is taller than most, but the weight of the 3/4” plywood gives it good balance plus the dust is captured at the very bottom.

I caulked the box with silicone and sealed the lid and vac motor housing with weather stripping. I also used silicone on the upper and lower connections on the dust deputy.

This thing really works well. After vacuuming my shop floor I had almost no dust at all in the upper chamber, where the filter is.

thats pretty cool LOOKING but im not sure what the whole purpose of it still only have a small container to hold the chip and saw this all about not wanting to clean a filter? seems to me that all the time and money spent you could have bought a dust collector that holds more waste

I think it’s a great idea.
In my mind using this type of collection system keeps the filter clean therefore allowing the vac. to keep the same suction rate and not loose suction by filter clog.
Time well spent no matter what!
Thanks for posting.

oh wow it looks like a crazed R2D2! Fantastic, I might have to add that little guy to my list.

An LJ hat and t-shirt on the DC and it could make it a companion in the shop.

Thanks for all the great comments. I use this on my router table and spindle sander and to vacuum the floor etc.
I have a central 2hp dc unit that takes care of the rest of my stationary tools.
I may hook the router table up to the central system one of these days. Right now the central system has the old bag filter and I plan to get a larger cyclone for it as well. The best thing about the cyclone is keeping that filter clean so you don’t loose suction, you don’t put as much fine dust back in the air, and hopefully you won’t buy near as many filters.

I know this concern is probably redundant, but suggest everyone use a hepa-filter (.5 micon) on the vacuum. Even though the cyclone works fantastic, I still find this filter takes out the VERY small particles that one can’t see but causes all the problems with the lungs.
