The reason you got a lot of blowby in that cyclone is twofold: The cyclone is likely too small for the flow of that shop vac. A cyclone requires a huge drop in air velocity for the dust to fall out. If the flow is too high then the velocity is too high and it won't fall out properly. There needs to be some distance between the blower inlet and the cyclone. This is a little more technical, but basically the velocity at the blower inlet is much higher at certain points in the pipe cross section than other parts. The high velocity sections carry dust, then the dust clogs, then the high velocity section moves, more dust clogs, etc. Eventually the whole inlet is clogged. Adding about 5 pipe diameters of length allows the flow to "develop" and be more uniform when it exits the cyclone. I know what you're thinking: "why should I trust this random handsome guy in the comments section?" Well, I'm an HVAC engineer that specializes in industrial ventilation, so I've done this once or twice.
@@groundzero_-lm4md I do not have a formula for sizing cyclones. It would depend on the nuances of the design per the manufacturer. Manufacturers will publish an airflow range for their cyclone, so you need to ensure your flow is in that range. Generally, do not exceed 2/3 or 3/4 the listed capacity of a cyclone because manufacturers tend to overpromise.

The non-linear editing on this is fantastic! I haven't seen a video do this in the woodworking scene in some time. I think when you aren't showing details/how-tos on something, and just the process/progress of a project, this is an excellent format. I do prefer how-tos and insights into process and order of operations, though you just shifted from woodworking focus to problem solving focus, which I can also appreciate. Well done. Love the humor in this channel, and the constant upgrades in quality have been noticed!
Absolutely brilliantly written and edited, seriously, letting us watch you build the newest one while telling us about the past trial and error was absolutely perfect. Perfect.
I wonder if he is going to post his fingers getting routed off. When a table saw chops off your fingers, sometimes they can sew them back on, but with limited usefully for the rest of your life, but a router makes hamburger meat of your fingers and you spend your life with nubs if you are lucky and don't have nerve damage which can lead to never ending pain.
I absolutely love how you incorporated two pieces of glass into your build. An easier option would have been acrylic, but that would get scratched to oblivion with time, this won't. Genius
never use 90 degree bends, however, thanks a million for building something with a throw away vac! Few people repair or repurpose anything. Thank God this vac didnt end up in a landfill! Good job grasshopper
Very much enjoy your commentary throughout all off your videos, as they provide a great window into your thought process, including what didn’t and did work. I’m now inspired, here early in a Sunday morning, to complete my shopvac cart. Thank yiu!
While I don't intend to make a cart, your final design is similar to what i want to include in my bench, and this video has definitely helped me nail down some of the remaining thoughts I had kicking around. Thank you for making this!
I like the way you explained your thought process on solving a problem, and you're not alone, I thought the same thing of "eliminating the middle man" however I'm glad I didn't attempt to make it myself... you made me realize that it's more complicated than doing the obvious... still not sure _why_ it failed, maybe it has to do with the length of hose to the shop vac? Anyway very interesting, thank you for taking us along for your journey! If you need to make a dust bin for easy emptying, consider a plastic bin, you'd have to modify the front of the cart by making it a door that you can open and the bin can slide out, so if I build something similar I might go vertical to conserve shop space... hmmm... now you've got me thinking... and that's probably not a good thing. 😁🤪😜
Ohhh yesss. Blue while running normally changing to Red when full. (And therefore ready to be sucked clean with a bigger vac, which, when that gets full gets sucked clean by an even BIGGER vac made purely out of Bubinga and Purple heart. Why... because well... otherwise, "it's annoying" lol).
@@keithroberts7502 Good idea,, Progressively larger and larger shopvacs for all eternity.. Over the past several years in my *dust collectionless* shop I've had to scoop up probably a half ton of sawdust of various types with my high tech shovel and broom.. Enter the B&O railroad building a train spur to carry away the many shopvacs from years and years of....Well...you know..
Smart use of a flush trim router bit and some straight wood to clean up an uneven cut. I'll have to remember that. Go watch the Stumpy Nubs video and make a table saw blade guard 😁
I really love this channel. I think what is most enjoyable is the way you design-on-the-fly. I used to do that, and sometimes still do. Nothing more fun than spontaneous engineering. :)
I bought such a small cyclone from eBay it's about 10 $. Had it laying around for 2 years now and I'm about to finish my workshop. For what it is it's very efficient. Like you, I made a solution with a vacuum cleaner engine and the cyclone connected in series. The whole shebang is outside so I don't have to listen to the noise it makes. I made a box for my compressor and it's also the place for the dust collector. It works quite nicely. :)
Hi Robert, I do enjoy your videos, you seem to have a good time doing your stuff. I actually did this before you and tried the cyclone and discarded it, put the pick up tube in the side creating a cyclone. While it works as well, the filter still gets clogged with very fine particles . Mine does not lookas pretty as yours . Keep doing what you do , I'm always happy to watch your videos. Really enjoy your style
I think you should take cue from Dr. Heinz Doofenshmirtz and add "inator" to the end of everything you build. Dust collector-inator with self destruct button
You may have watched too many “kids” cartoons. On another note. Perry the Platypus is an awesome secret agent because at first glance he just appears to be a lazy platypus.
I have - it can be very effective. See +Garret Ducat ‘s reply to why it is a little more complicated than throwing kit together :) But the cascades work well if you size the hoses right - first bucket has 98% of the crap in it, the second bucket has fine powder in it and the vac filter lasts a looong time. But since I lacked the workshop and Dunn’s skills (and, frankly, stylish design eye) I got tired of balancing the stuff and went back to one bucket - and regular washing of vac filters :)
Hahahaha. I loved your video. It kept me interested and watching all the way through!! Fantastic project and I really appreciated the way you told the story showing the construction of the project while telling the background story. Very eloquently told.
Sweet. A lot like mine, but no need for the Dust Deputy. My Dustopper works great! And is way shorter the the over rated DD. It sits right on top of a 5 gallon bucket. The bottom is cut out to allow for a huge dust reservoir. Then it has a table top above the Dustopper & shop vac. It is all built into an old cart. The unit acts as a portable shop vac cart, assembly / feed-out table, and a rolling power strip. Looks rough, but works very well. :)
I really like that. As far as emptying the dust you collect, maybe try making one side of the dust collector a slide out drawer that you can pull out and empty. It would have to have it's own windows, but it would make it a lot easier to empty.
I got into woodworking over a year ago to build a piece of furniture I need/want in my house. Thankfully I've been making other stuff instead so far cuz I can totally relate to "nothing I make looks good"! Lol. Glad it's not just me. Altho I guess I'm alone again cuz that is VERY pretty!😝
I've used the cyclone to good effect with drywall sanding, concrete grinding, and wood shop. I have a cart for it connected by a shop vac hose to my shop vac. It's bulky but will fill four five gallon buckets before the filter needs tapping.
I too have been marveling over Frank's Frankenvac setup. I like your build because you didn't use a CNC to perfectly cut ever part. It's a great build. I want to learn how to CNC and do video editing so I can animate clamps to crawl across the screen...
I have less sawdust to clean, so I just took the bin of a Dyson DC05 and connected it to an old industrial vacuum cleaner (only 600 watts) which can run all day long without being overheated. Works great!! 😄
My cyclone (made by dyson :D ) has a compresion funnel, outside looks like yours, about double the diameter, and, has another cone inside of it, the air comes into the cyclone and is compressed while spinning, the inner cone, ends around an inch, before the outter cone, air has to take a sharp bend to go up into the vacuumizer. Then is goes into a paper filter, about the size of yours. I vacuum cement (from drilling, and breaking walls), sawdust and even my shop floor with it, the deposit fills several times, a lot of times, before the vacuum power level starts to show up. The power level is just two like a syring where the inner part is spring loaded, the more power the motor makes to vacuum, the more the meter shows up in the window, very common with old hoover home vacs to indicate a full vacumm bag.
Awesome video! Love seeing all the iterations of, Tried this, nope, didn't work as expected.... Might want to grab some fleece cloth and make a filter cover or just but a filterpal bag to go over the filter to keep all of the fines out of your actual filter.
It's beautiful!🤣🤣🤣I recently discovered your channel and after watching a couple of videos while chuckling I had to subscribe. I'm new to wood working but I have suggestion for emptying the dust collection section. Why not install a large plastic trash bag in that section? Once the bag fills up remove, empty and, reinstall. Of course you will have to find something else to do if you get bored and, if it works. Because the glass will only allow you to see when the bag is full.😁

I very much approve of the accents of brown
I'm sure Mr. Regular from Regular Car Reviews would too.
That shade of dark orange really does complement that other shade of light orange!
Brown is my favorite color!
Still waiting on my brown scittle
Brown? Don't you mean "dark orange"?

You’re an engineer and you can explain it in layman’s term.
Well done. 👍🏻👍🏻👍🏻
Is there a formula for the size of cyclone needed vs air flow? On household vacuums they use a lot of small cyclones.
@@groundzero_-lm4md I do not have a formula for sizing cyclones. It would depend on the nuances of the design per the manufacturer. Manufacturers will publish an airflow range for their cyclone, so you need to ensure your flow is in that range.

Yep... removing the filter and shorting the distance caused too much airflow
But I loved the project and have subscribed!
Is the distance part of why the final version seems to work so much better? The loop of PVC pipe looks to be well over 5 diameters in length.
Overbuilt yet still Under Dunn. I like it!
There's something so _pleasant_ about your editing, especially in the woodworking series. Great work as always!
Perhaps the lack of lofi background music (which I much like, but it grows old) and instead just the sound of his machinery?
It probably has something to do with the fact that he's clearly having fun with the editing, so some of that comes through to us.

This video is like my own DIY in a nutshell. Spending days trying to solve a problem that you have needlessly created yourself in the first place.
That "Router Table" setup you have is only mildly terrifying.
yeah .... but only 'mildly"
Speak for yourself, I’m very terrified.

I'm glad you showed the dust dropping into the bin, made my day.
It's a hell of a flex to make your shopvac look that nice!
Looks great. It's nice to see someone take pride in their work. Well done.
