I decided to make this after emptying out my HF DC for the first time, what a pain in the ASS!! Another reason was to help out the HF filter bag. I would say this gets everything over a 5-10 micron if I had to rate this. The picture of the trash can is the dust from the drill press table I just made out of MDF.

This is a great i mean GREAT shop addition but, I did notice a little less suction from before. We’re not talking a lot here, but I did notice a difference. Then again I do have the HF and the impellers are only 10 3/4” not 12” like most other brands. I had plans to run ducting to all my tools, that’s why I made my wye going vertical b/c I had wanted to run a flex on the ground to my TS and the other side to run up the wall to other machines. I decided to stop putting money into b/c I think I’ll be more satisfied if I get the Tempest 2.5 HP Cyclone – 1450 CFM, up to 12 drops and a 50ft run, plenty for a garage shop and I think this will get me what I’m trying to achieve. As you can tell I HATE SAW DUST, but then again who likes it?? lol

That is nice. I was going to make one , too but I saw the Dust Deputy on sale and bought it. Then the top broke off and I called Onieda and they said to go out and by some polypropolene glue- no there were not going to send me any or give me a new one. I’m going to fix it right!

Thanks for sharing this separator!!

Great job! I hate changing the bag on my DC. I did figure out a trick though doing it my self. I use magnets to hold it up while getting the band clamp in position. It made it so much easier.

That’s too cool. I made one too, but I had a regular dual bag air handler I plugged mine into.

Ken, you still have to empty these fairly regularly, especially when you are using the planer. That can can fill up fast! (Wanna dance? ;)

i love my Thien. just love it. almost nothing makes it through and its so easy to empty!
one thing that i noticed – it makes the DC quite, so you might think it has less suction. the reason for the quietness is that shavings to not rotate in the dc bag anymore.
