Thanks Chef Goyar-D for the tasty beat : chefgoyar-d.com/ - วิทยาศาสตร์และเทคโนโลยี
I feel click-baited but simultaneously properly led on.
I was thinking that he using hairy lion 3d print technology for the brisels :D
For your VacJet, make a cyclone. Instead of introducing the air jet in the centre, bring it in from the side at a tangent to the opening of the funnel and level with the rim of the opening. This way the air jet will spiral around the surface of the funnel and add pressure to the vacuum. You might have to lose the perforated cap. This will stop the jet overpowering the vacuum. It will however lose the blast to get into the crevices.
Maybe make a hybrid of both? Split the air jet, so half the air goes to the centre jet, and half goes to the cyclone. Just an idea.
With your CNC vacuum, would longer softer bristles help seal the airflow, so you are only sucking around the bit? Or modify your existing brush, so it sits on the surface being cut with a telescoping tube joining it to the cutter / vacuum head. That way the vacuum brush is always in contact with the wood being cut, but will adjust it's height as the cutter drops.
Thanks for another great idea filled video.
A crazy hybrid cyclone vac jet sounds right up my alley :D
So are you saying that a good cleaner sucks while it blows?;)
This video is full of Hose, sucks and blows
Damn
I knew someone would have said
this lmao
Oml someone stole my job wrecking up like numbers
get some collapsible tube to put between the bristles and the mount that way as the spindle lowers it can compress. Also I would get softer bristles.
That is a great idea! Hey nice.
for the blower sucker, you can put a curtain of brush bristles around the perimeter
Use a clear but really flexible brush, and they taper toward a point kind of like this: ====>
That way you can clean things in a lowered pressure environment and also use a lowered air pressure.
@Make Anything - Devin, try printing an inverted funnel out of flexible filament, such that its bottom (intake area) can be closer, or even possible squished against the material being CNC'd. This should increase the suction in that area as well as physically disturb removed particles, making them more likely to be able to be sucked up. The biggest theoretical drawback is the possibility of the flexible material doubling back into the drill itself, so it might take a few iterations to figure out the optimal shape and size. This design would also drastically reduce the need for bristles.
Make some tpu gaskets to seal up those parts on the cutting end of the vacuum, and I'll be you'll get a ton more suction.
I really enjoy the 3D printing shop projects! I would also love to see you combine 3D printing with the CNC and other woodworking in future projects :)
You can count on it! As long as the CNC survives
I just found your channel because I'm working on a school project about compliant mechanisms. I watched some of your videos, you're very creative and definitely deserve more subs!
I used some kind of combination of vacuum and a compressor for cleaning cars.
And let me tell you, with an enormous industrial vacuum and a big compressor, it was powerful.
The compressor part was a bit more recessed in there, and rotary.
An augment to the bristles (you would probably have to recreate the tool) would be to add in a wide, weak-ish spring to have the bristles literally press against the work at all times. It would kind of drag, but if this spring were made of plastic with holes for arms (basically, a slinky) it would probably prevent the tool from wobbling around unnecessarily.
the way you used two colors of bristles is absolutely adorable
Vac-jet: I've (too many) ideas:
- generally increase the size of the cone so that there's more holes for air to travel to the vacuum
- Add bristles to keep dust from escaping the suction of the vacuum
- If you try extending the cone (like what you suggested in the video), also angle the nozzle of the air compressor to (hopefully) create a vortex (a bit like like the way your dad's dust collector is working)
- make an outer layer to the cone and send the compressed air through that. Maybe try to find a way to direct the compressed air in towards the center of the cone and towards the suction.
From a cnc router guy you might want to use a less firm bristle
and maybe bristles that are at least as long as the end mill so that when it plunges down into the material they create a sort of cup around the tip of it to enclose the area strengthening the vacuum and keep the chips within that area of stronger vacuum pressure. Or maybe you can do some sort of multi layer method with shorter stiffer bristles on the inside and longer softer bristles on the outside. The less gaps that air can get out through or the harder you make it for air to get through the bristles the stronger the vacuum will be at the tip.
Hey maybe surround the vac jet cone with bristles to strengthen the vacuum force around it too!
I like that the parts are a work in progress and you show your failures as well, feels more involving.
How about a tpu attachment? This way it can compress as you lower the bit and enclose the sawdust in that space and don't 'waste' vaccum power?
read my other longer comment pls
Loose the bristle brush and replace it with a telescoping ball end to equal the distance of the end mill. The ball contour will glide over the parts being worked on. Or you can install bristle brush that telescopes up and down.
💕 Wow, is there no end to your imagination and creativity ?? You've got to be so handy for your dad. 😊
Keep bringing them, dude ! 👍👍👍
I LOVE COOL PRINTS!
I love seeing all the cool functional prints you make! I cant even begin to count how many things I've fixed in my house with 3d printing!
Possible design upgrade for the cnc dust collector, add a soft(easily compressible) flex hose between the brush & its mount so it pushes the brush into your project but allows it to move inward for those deeper cuts! Also for this to work you might have to add guide rails for the brush so it can only move up & down, not side to side!
I'm sure it's been mentioned by others but a retracting brush system would greatly help as it would be cutting inside the vacuum as opposed to below it.
Man I love these programs when you create a solution for a problem. You are so damn smart, very very clever! You have such great ideas that I hope some really smart people are watching that can't expound on, because I can imagine that vac-u-jet arranged properly could be turned into like a super house vacuum?! A regular vacuum cleaner but it jets air in pulses, freeing the dirt from being trapped but leaving enough time to be sucked up by the vacuum. You know stuff like that
The VacJet might seem counterintuitive at first, but the concept works really well, I use it on my t-slot table on my manual mill.
You should turn down the pressure on your compressor. I have it set to 3 bar, but I use about 1-1,5 bar. (it's a confined space tho, the air can escape on only 2 sides, other than into the shop vac.
Maybe a slim long nozzle would be good, and maybe the air nozzle on one end pointing slightly into the direction of the vacuum hose.
Also, you could spring-load the brush part of the dust collection on the CNC. Either downwards directly onto the part (good for slotting or very small pockets and easy to set up), or spring-loaded upwards and distanced from the gantry. (If you want sketches or models, send me a message)
The next time you cut with the CNC, try using the adaptive toolpath in Fusion It improves tool life. Plus it's super satisfying to watch. ;)
Why not add a loose tube to the CNC suction ring so it can telescope down to the work surface? You could restrict it with a string to the X carriage to keep it from dropping into pockets.
that wouldnt work well because if it has to move back, the telescope thing would snag on the step and break. also read my other comment!!!
@@patrioticpengu1n the other comment I could find said to read another comment.
that vacjet thingy.
kinda reminds me of the sandblasting nozzle we have at work. the cone is about the same size, and it has a tube inside that blows the sand, that is then sucked back into the sandblaster by the vacuum.
the difference is that the jet inside the nozzle is approximately 2cm (about 4/5 of an inch) inside the cone, its still powerful enough and makes a sortof a vortex inside the nozzle.
and the cone has a ring of brushes on the edge.
you could implement roughly the same principle here. have some sortof brush on the edge of the cone similar to the dust collection bit. so you can cover a rough area with the cone without blowing the dust away. and have the pressure a bit deeper inside to create the vortex, instead of blowing the air far out of reach of the cone.
You are so talented Devin! I’d love to see a video of HOW you make your videos...setup, lighting, filming including B-roll and editing! You are extremely creative....keep it up!
Add either a rubber seal around the rim of the blowvac or a dense hollow bristle brush around the head.
The vac-jet could be great if the grate was a concave shape like you suggested. It may be interesting to see if a greater or smaller diameter works better or worse. Another variable might be where the grate is located relative to the lip. Can't wait to see an updated video :D
So for the Vac-Jet you could adapt the ratio of blowage to suckage by making usage of the Venturi effect. Basically make a split in the line that the air blower goes to that has a tube to turn the air around and force it down the hose increasing the sucking force of the vacuum and decreasing the force of the air blaster. you could balance it by using a pair of set screws or preferably a method that is faster to adjust to locate the nozzle at the exact point you want so that if you wanted you could easily turn it to full strength air blaster or extra strength vacuum with the air blaster fully directed into the vacuum. Also just thought of this after the CNC project and suggesting the cone around that one but if you surround the vac jet cone with bristles to strengthen the vacuum force around it it will also help keep the chips contained so that might also make it work! either way there are 3 more things you can try for your project!
Make the diameter smaller. You've drastically decreased the power of the vacuum. Also, small brushes on the outside will help contain the power of the exhaust.
2:37 had me laughing out loud. Cool vid!

Es saugt und bläst der Heinzelmann wo Mutti sonst nur saugen kann.
@@me3dnone107 😂🤣👌
The VacJet you printed up is actually very similar to a device we use in a cleanroom where i work. Just like your workshop, we can't have particles flying around in the air or they will contaminate the tools.
Nice. I created shop vac attachments as well. Really helps with my orbital sander and router that don't have anywhere near the same size fitting as the shop vac. Also increases the suction as you step down to a smaller hose at the end! My suggestion for you would be to lengthen the brush fitting so the hose and bristles extend lower closer to the bit, putting the suction point closer to the piece being cut! Should work!
I was just worried about long bristles catching the end mil, but I suppose it would depend on what I'm cutting :)
@@make.anything shorten the bristles by extending the tube lower, thus lowering the suction. Bristles are possibly not needed. Dust is fine and they don't need to do anything in this type of project.
... on both projects: the trick is to have a smaller diameter suction cap. Smaller than the hose. Create some nozzle around the edge and you should be golden. That way the air is forced to go in faster which increases the suction.
great content as always, as 3D prints are permeable, you could try acetone smoothing ABS prints to get more suction force out of your shop vac.
What if the jet port blew the debris toward the vac port? I think you're also losing a lot of suction because of the screen. Could you have a magnet in the line, maybe inside chamber to reduce the local suction within that area?
For the CNC, you need to more reliably reach the milling surface. Longer, softer, but more tightly-packed bristles might help. Or a compressible hose/sleeve? Can you hook it up with electronics that know how deep you're cutting and adjust the length of the suction aparatus? What you kinda need is a series of spring-mounted pins (like a gator socket) that could ride the surface of the part you're cutting while maintaining a seal against eachother. With beveled edges so the could ride in and out of cut holes. Gravity might be able to do it, too.
I've been considering designing a vacuum housing for my hair trimmer to make a modern flowbee.
I would try some softer and longer bristles, and mount them angling outwards a little so they can compress and bend away form the drill bit when it moves down .
YO TIP FOR YOUR VAC-JET: Im a mechanical engineer and one flaw of your design is that the vacuum chamber is diverging which means you are slowing down flow at the front. instead keep a similar cross sectional area to you vacuum hose tube or even make it converge in slightly. This will increase flow speed there thus sucking air faster.
Also for your shop vac you are restricting flow with that one inch hose being so long and then your bristle brush end is also larger than 1 inch so diverging again. This has the effect of decreasing vacuum suction and flow speed. It kindof sortof works but you would get a much better result if you had the same diameter hose all the way and a smaller opening at the end. That would increase suction and flow.
There is only so much a bigger better vacuum can do... Sometimes physics does the rest! Fluid dynamics can solve your troubles in this video. No need for a bigger more expensive vacuum.
Good advice, thanks!
What if you put a little internal propellor? With a high pressure sprayer it makes the water spray more powerful
You are so creative. Awesome.
im watching this at 2 am with a lukewarm glass of lemonade while my parents yell at each other about divorcing upstairs
The vac jet would work great if you put that little cnc dust brush on the end of it. The air compressor would still blow it everywhere but the brush would catch it.
Episode 6: 3D Printed Shop vac since my old one was to weak and I thought it would be fun to design one myself.
I'd had the same idea for the *Vacjet.* High 5 😀. Never went past my notes tho.
I have the notes somewhere, but iirc one idea was to split the compressed air stream into a ring of outlets around the outside, all facing inwards a little maybe (or just spinning around like an air vortex), to create a sortof *air-curtain* to keep dust from escaping. Then the vacuum was in the middle. Feel free to try that out, i got that bane of makers where i've got way more ideas than motivation/time.
For the dust collecter on your CNC, I'd try a flexible print head at the end instead of bristles so that there's more suction closer to the end of your bit. Perhaps in ninja flex so that it can deform and reform without problems.
Dude some fantastic ideas you got.
What you need is some form of bellows to keep the brush touching the work surface
For the sawdust circular vacum, you might want to design a 'hydraulic' tube or add a spring so it can move up n down and a lot closer to the dusts
I immediately thought of "TOP OF THE MORNING TO YA LADDIES" when I heard the whip crack at the beginning.
I get it!
Maybe just extend to lower bit of the suction nozzle closer to the bed and make it narrower to aid in clearing the sawdust?
@_ David _ Gotcha.
Maybe for the bristles, you could make a smaller ring that you glue the strands onto, then a larger ring that encompasses them, glued on from the outside, and then mounted onto the machine...
This is way harder to convey in words than the way I thought of it in my head
Awesome inventions that seem to work well. Now if only you had a vacuum that actually worked they would be flawless.
For that cone in the beginning, maybe make a contraption totaly on the contrary, the outer circle that blows towards the center that sucks in?
I was thinking the same thing just now! It would be fun to try, at least
Get yourself a high RPM electric motor and a blower wheel. Salvage one from a washer or dryer etc. Put it in a wooden box with a hole on top (intake) and on the side (output) that leads into your collection system. Or just a cloth dust bag which would remove the need for that huge box.
Hi, you should use hoses with bigger inner diameter. The suction is directly related to the diameter. What makes it even worth is spirals inside the hose, this also reduces suction. So get big hoses with smooth inner surface and you are good.
Very impressive! You are a good designer.
typically a dust shoe for a CNC would have bristles that extend down to the work surface, so no dust can escape. You'd basically have bristles as long as your bit.
you need to print an adapter to enable the depth of the brushvac to be adjusted
add bristles to the jet vac. and maybe create a telescoping fitting for the cnc vac attachment
I do not own or use a cnc but what if you have a few nozzles blowing the dust to one side of the cabinet and vacuum them away from the opposite site if the blowing vents?
You should use the exhaust from your vac for blowing on the tool head and for a contiuous stream out your jet.
You could make that the brush gets pushed higher when the rotor cuts deeper!
I think, for the " vac.jack" you need to reduse presure from compressor to ~1-3 bar for good clean!
2:40 For those who haven't experienced it, it's amazing
Did you check if the filters/bags of the shopvac need changing? Old filters/bags may make vacuums weaker as they clog up the airflow
Add a divider to the piece that holds the attachments so you could have another hole on the side of the drill
Could add a flux capacitor to the inside of one of the sides of your cnc cabinet. adds 20 cool points!
Extend the vac-jet chamber on the front by putting a brush around it.
Thanks for the video.. what about a lever that opens the vacuum port more for suction or adjustment ?
Yep you need to get a stronger vac the design Is good. Grate job.
That exhaust adapter needs to be properly affixed to the CNC enclosure. Perhaps with some screws and a rubber seal.
And yeah, definitely upgrade your shopvac to something more powerful.
What about converting all your smaller hoses (looks like 1" and 1-1/2") to the 2" like on the exit of the vacuum? Yes, it will take more "hose-management" to keep them out of the way, but it's possible you're losing a lot of your suction force in both the vac-jet and the cnc to the smaller hoses. Just a thought...
Have you thought about using an air multiplier system for dust removal?
When you go from a thin hose to a wide nozzle, you loose suction power. -- Your nozzle is designed to weaken the vacuum. If you go from a thick hose to a thin nozzle, it will increase the force of the vacuum. -- You should consider extending the bristles to the tip of the cutting tool, IMO -- if you make the plastic bit longer and springy (maybe springo it?), plunge cuts would still be possible.
What about a telescoping, spring loaded (to stay down), with ball bearings in the end to replace the bristles and bring the vacuum closer.
Try connecting a fan blade to the spindle so you won’t need the shop vac
Do a vid on upgrading the shop vac and use drain pipes PVC with slide stops to route it to a location.
awesome design.
About VacJet.
You need to slow air flow. The easiest way is to increase the output diameter for the air. Bigger hole >>> slower air speed =)
Play with diameter.
Regards
There’s suction being lost somewhere it’s either the strength of the vacuum the connection of the hose or the chamber the vacuum has is not completely air tight
4:10 Me when I use a perfume thats not mine 😂
hey there, just saw your sawdust vakuum, i would recommend to use the ciclone technologie (like dyson does) to vacuum so you have more power or better said you dont lose power over time.
0:25 Here in the garage with my 3d printers, but do you know what I like more than my 3d printers... KNOWLEDGE
You're probably loosing a lot of suction from the length of small hose going to the end mill!
If you feel like making a mk II, I would get hose with a similar diameter to the shop vac, maybe even upgrade the shop vac to the larger hose type, so theres as little resistance to flow as practical.
Also make sure the coupling between the hose and the opening around the mill is as wide and open as you can make it.
There's a similar issue going on with your vac jet, by having the wide opening, you are spreading out the air flow and reducing the suction force. Since the filter is a factor limiting the airflow, its good that it's wide, but if you taper the cross section back down after the filter with an extension, it might make it more effective, and give you a really groovy retro sci-fi look!
its probablu clogged from the massive ball of shavings
For the VacJet you could but a lip on it for flat surfaces and then when you use the blowing part it wont go anywhere.
I should've watched a minute more. He said the same thing lol.
Try making a vac jet adaptor that uses a lower pressure source like canned air or a lower psi electric blower.
2:37 I need that in my life
vacuum machine+wood drilling machine. Great idea. That could save lots of time on cleaning.
Maybe the suction force would increase with a longer tube, if the tube where made flexibele, and springloaded, you could control the distance with an attached string, the string lenght could be controlled by a small stepper motor, and that should get its information from the cnc driver, to control the distance to the workpiece. it that is not possible, an attached hall sensor could detect the distance, what do you think?
one of the few times I don't mind being clickbaited
Should hook up a second shop vac for extra oomph. 3D print a dual adapter on the intake.
Great design but I would make the bristles longer to enclose the vaccum area 👍
I wonder how much electricity that would use if you have to have the shop vac on for hours at a time while the CNC is running. Also, maybe it would be better to use the air compressor in the CNC too, and not use the vac at all.
Really cool thanks xx
5:30 what material are u using because I think PLA will soften if the router gets overworked
Get yourself a higher powered motor and 3D print yourself an impeller to create more suction for your CNC.
your videos are cool :-), im not trying to rebuild something but it's anyways entertaining
me suddenly loughing in class my brain 2:36
