I built this Cyclone Lid for my trash can a few years ago, and originally had it set up to run with 2.5” shop vac hose. It worked great then, and recently I modified it to work with my dust collector and 4” hose. It works great now too!

I must give credit where credit is due: I (loosely) followed the plan from “The Thien Cyclone Separator Lid
w/ the Thien Cyclone Separator Baffle” Google it if you want the plan.

I used it the other night to plane down some cherry and walnut boards, and emptied the trash can 3 times in the course of 1 hour… And my dust collector only got about 2” deeper with sawdust. So, mission accomplished. The messy task of emptying the dust collector can now be done MUCH less frequently.

One note that is probably pretty obvious – this unit does impact the suction a little. I don’t have empirical data, but it feels like there’s not as much CFM when I rout the house thru the cyclone. It’s still plenty sufficient to suck up all my planer shavings, so it doesn’t bother me.

Good ol’ Thein…......... Great Job!

One thing you may want to check is that you have a GOOD seal between the can and the baffle – it will improve your suction. Take some weatherstripping tape or something similar. I modified a plastic garbage can and integrated the lid into the system and still had to seal in between the lid and the can. I can’t notice any difference in suction.

Cheers!

Thanks Bob. Yep, it seals well. You can kind of see, in picture 4, I have some weatherstripping around the rim.

I made one of these for my dust collector a couple of years ago, and man do they work great. You will be happy you have it. Well done! Take care, George
