Centrifugal Dust Separator - Dust Collection On A Budget

"We all become better builders because of the contributions we make to each other." Dude. I'm an instant fan.

Insanely good video! To be able to get 94.2% in a DIY setup that has not been optimized through the R&D capacity of Harvey while using a smaller diameter setup is stupid good! Folks will rarely appreciate how much time and effort that went into the making of this video. Really well done!

I watched this video specifically because you said you were iterating on Under Dunn. I am glad I got to see this impressive work of yours.

Beautiful presentation and execution. From a 3D printing perspective: Vapor bathing the parts will reduce surface friction. From a dust collection perspective: One major reason for having a 2 stage collection (Vertical or Lateral cyclone) and then pleated air-filter is the protection of the impeller from debris, as such, attaching the blower after the cyclones is an opportunity for improvement. This also allows you to fit the cyclone with the exhaust pointing down into the Wynn style filter. A specific improvement: The dust collection chambers should be isolated (all 4) to prevent cycling flow. Part of the efficiency of the cyclone separator is that only acceleration affects the dust particles after the inlet of the next stage. With the dust collection chambers joined, a flow of air will create cycles between the two cyclone ports and allow dust to pass over the port on one side. Furthermore, offsetting the vertical port such that the rotational flow of air can proceed directly down into the dust collection will increase capture of the particles.

How do you not even have 1k subs? Your video presents like you have 500k or more. Subscribed. Great content.

Was expecting 80k+ subscribers from how good the video was. Well, you got one more now.

Fascinating to see someone follow up on the Underdunn video. Huge amount of work to design and print those files!

Adjustable air speed/flow is definitely something to look at and relatively easy to implement with a speed controller on the motor. I think the "dwell" duration of the particles as they pass through could have the biggest impact on the filtration efficacy = ) Great video edit, very informative and detailed !

Excellent work❤ IMHO try taking off the buckets and the oblong to round adaptors and use bins like Harvey and Underdun, even if you just screwed a couple of tea chests as a rough and ready or better still large storage boxes like the black ones a Costco or the transparent one from Meiste. Also rather that weigh what you have collected in the buckets, weight the exit filter before and after. That way your are not second guessing how much is left in hoses etc.

Looking at the Harvey cutaway, they have a much more aggressive pitch on their vortex generator. Thier's are more of a "J" shape and yours are an "S" shape. I think they are getting a much higher rotational speed, and therefore more centrifugal force for separation. With a bright light and slow motion on your camera, you might be able to measure your rotational speed if you can see the particles through the tube well enough. Harvey claims 4000 rpm, which is ~66 revs/second. At a frame rate of 120 fps, a particle would be half way (180º) around the tube from one image frame to the next.

your editing is great. you demonstrated your point and didn't drag anything out. I wish more youtube videos were like this. On the subject of saving money, I would make a filter bag for the inside of the canister filter. That thing looks like the most expensive part of the build lol.

I did something similar as I 3D printed a cyclone dust separator for my shop vac. One thing I immediately noticed was the static buildup on the plastic parts. This, along with the ridges that are created from 3-D printing, create a significant flow disruption, which doesn’t allow the dust to fall out of suspension in the air. I have used UV liquid resin to fill in/ smooth plastic in the past prints to make it smooth.

gotta say, the production value on this video is amazing! great work!

Try a ridge on the downwind side of the exhaust ports to deflect solids into the cans.

i saw the under dunn video a week ago you have no idea how excited i was when i saw you already designed the full system, now i can print it to!! hope your channel gains some track so we see more of this content in the future, im already looking forward to more

The buckets will collect more dust if you give them a little exhaust also. Maybe some filter cloth over an array of half inch holes. There is back pressure in those buckets preventing the particles from going in there.

This was an incredible build video - THANK YOU

I'm only 6 minutes in and already enjoying your approach to explaining the build and the editing. Enough glitz to make it enjoyable but still showing the engineering challenges. I've just seen that you only have 1k subscribers!!!!!! That cant be right for such a well produced channel.

Great video and great tips for us woodworkers on a budget and need dust collection system so thanks for sharing

Came here for the dust collection, subscribed because that's the best DIY for this I've seen. And I love guitars, so bonus!
