- เผยแพร่เมื่อ 25 ก.ย. 2024
- As my old blower destroyed itself I had to make a new one. This time bigger and stronger.
This first video of it covers the mounting flange and the impeller. Everything in lots of detail.

Enjoy the video!
Marius, your videos are full of integrity because you point out your own mistakes, which makes you more real to us, your viewers, and adds to your integrity. Because of this, we trust your opinions more and are more open to your design suggestions.
I love the imagination and ingenuity. I also love it when non-commercial woodworkers (like myself) spend 75% of their time making things for the shop. Great video. Keep it up.
I don't build anything with wood personally, but I admire people like you who do. Also, I loved seeing the outtakes.
Brilliant! May I say for your age your ingenuity is very impressive - ignore the trolls and keep the vids coming - a 65 year old learning loads from you!
Thanks for sharing this. Learning from iterations that didn't work out can often be even more helpful than learning from ones that did.
Even Rolls Royce had a steep learning curve with blown turbine blades on aircraft engines as I recall. Good Onya for persisting with it, teaching yourself and us heaps in the process.
Whoa, you open a drawer and..whoosh..a truly monster tool emerges. Crazy.
Hi Marius..when my shop was building wooden impellers in the 80's..we would epoxy coat the vanes to help with surface wear. We found the vanes would wear and eventually self destruct uncoated. We also put an hour meter on each impeller head so that we could schedule periodic tear-downs and inspections. Just a couple ideas for you.
My fins have three coats of oil based polyurethane on them.
Remember too these vanes are constantly being blasted with particulate, you really want something that is going to stand up to that. Often the alkyd poly's have very low durometer and brinell hardness numbers. We experimented with wood vanes at first and they always failed for us. We later made a clamping mold where we heated PVC sheet materials in a small oven to get them soft, clamped them in the mold and when they cooled we had some very consistently shaped and long-wearing vanes. Good luck with the new blower! The project looks amazing.
Marius Hornberger which brand?
wxfield
How thick would the sheets be for a design like this? And how tall are the fins?
I like that you are not intimidated by your mistakes. You are a very good craftsman.
Oh, sure. Good assembly skills.
The problem is trusting plywood with THREE HORSEPOWER.
You made the biggest impeller on youtube for the smallest workshop. : D
Luv the outtakes, shows the human side and shows your maturity that you can expose the flaws as well. Great stuff. Enjoying your videos.
I appreciate you sharing your adventure. Some people just want to feel smart and have nothing useful to say so they say un-useful things that make them sound dumber. Keep up your experiments.
Marius, I really like your channel. Please don´t change your videos style, keep DIY culture ALIVE!!
Hugs from Brasil!
Very well done. For future reference, as a long time engineer dealing with fans, the commercial ones usually have an odd number of blades because they are easier to balance perfectly than the ones with an even number of blades. Thanks for sharing!
Marius,
You really are a genius engineer with so many clever ideas about the complicated machines (tools and jigs), that you design and build. Your use of materials outside their intended use and limits, is rather Impressive and quite inventive ... perhaps the best part of your work. Unfortunately Internet has given a platform to many unqualified and oblivious people who have no business to critique any ones work and life, but regrettably they do.
I am a retired industrial control engineer and I see in you the making of a great inventer.
Kudos on the work that you do ... entertaining and fun to watch. ☮
I love the fact you explain why things will work or not or why citing Newton's law for example. Keep doing it. Great videos. Don't change a thing.
I'm very happy you explained the reason for using the 9mm plywood. I love the design process.
hey Marius...the video was not too long..you are always interesting...keep up the good work....also the people who said MDF would not hold up have never used it...I've been a trim carpenter cabinet builder for 25 yrs plus....I've been using MDF for 20 years....used right it will hold up....you did a fine job both builds of the blower!!!!! keep it up....love your work!!
I think it's still taller than it needs to be. Look at the insides of a water pump, those impellers are really thin. Your hose only has so much area for air to flow, no need to make that so much bigger in the blower.
I like your take on dust collection Matthias. Just make a small one for every tool you have and then you wouldn't need a giant motor.
This is totally more fun though.
it helps a lot for experimentation to have one of those nifty airborne particle meters....
hey Matthias, i love watching both your and Marius's videos and i do honestly hate to be "that guy" but i suddenly had one of those OMG i have relevant information, training, and knowledge that would be helpful here! .. don't hate me and yes i would love to have in-depth conversations on this stuff because i am a huge nerd ,
but working in HVAC as well as doing instillation for central vacuum systems, for as long as i have i can understand why he used the larger impeller. yes there is only so much space for air to flow in the hose but you also have to overcome the shear distance OF piping and hosing. the distance of plumbing requires higher pressure of suction to have similar performance at the end of the tube as well as the beginning of the tube. water is non-compressible compared to air. so 1 gallon of water, at 3 psi will come out the end of a 30 foot tube the same as a 3 foot tube due to the non loss of compression of water. however when dealing with flowing air, every joint, transition, tubing change, etc will add "length" to the pipe and since air IS compressible it takes higher pressure as well as higher rate of flow needed to get the same (example) 300 CFM out of the tube at the end of the 20 foot run as in the begging of the piping chase. doing general calculations for the size and shape of the plumbing, its rated CFM, etc just like the big dust collector its going to need a hefty impeller.
the other thing i noticed with the small dust collectors rather than the larger systems is hes running the collectors like a vacuum cleaner system, where the dust is not entering the impeller but is needed to remain fairly strong even on the outflow to overcome the thick air filters, so in addition to high inlet suction it will need a higher outlet pressure unlike say your large shop collector which is only using a fiber bag rather than those paper type filters.
oh hi Matthias, I love your videos. I really afraid that the loading of these leaves is too heavy. it only built by estimation without measurement. But the workmanship is undeniably very good.
Great, awesome DIY (do-it-yourself) demonstration video. Your video informs & inspires people around the world. Thank... & thanks.
the last one in "outtakes" - classy !! )))
thanks a lot, Marius, for massive efforts you put in your videos! the part of "why" - is really appreciated
Love your videos. You and Matthias are my favourite builder TH-camrs.
at 8:25 I got hypnotised by the spinning wheel to the point I didn't even hear what you said and I needed to watch this bit again just to listen to you :D
Heck, even if this explodes, those blades are just beautiful. Never thought of using wood for things like this but you are making an art out of it. Thanks for sharing!
Dude much love for your videos! the outtakes are a great bonus at the end!!!
I really like all your attention to detail. This was a fast 16 minutes, excellent job !
Thank you for including the motor spec!
You're welcome
I'm currently looking for a suitable motor to build my own. Tempted to try stainless or aluminium fins instead of ply if you can't think of any reason not to.
+James Williamson how to join them toa wooden disk?
Ahhh yes. Epoxy might work but wood-glue-wood is probably better.
You should consider using a motor soft starter, when you're still in planing phase!
It eliminates the high-torque shock and thus mechanical stress on all components.
Great video Matthias. Don't worry about the people who criticize. Whatever you do somebody will find fault. I would recommend that you disregard the negative comments and move on. Of course, you know this. Keep up the good work.
Thanks. Though I'd prefer if you call me Marius
It amazes me how much you have accomplished. Hopefully it all works properly in the end.
Forget the negative comments, those armchair critics cant even make coffee. I admire your drive and when you decided to do something, you stuck to your idea and seen the project thru. it did work but like all lessons in life you have learned a lot from what you have achieved. Keep doing what your doing.
Absolute work of art. Bravo.
You will never receive any criticisms from me, as you are far smarter than I. In fact, I have learned a great deal watching your various videos, even when you make a mistake it is all part of the learning process. Besides, I think you are brilliant and I appreciate all you share.
Thank you Marius, another great video! Come for the fun and stay for the out takes.
I don't even understand what he's building, but I love watching it. Keep up the awesome work!
It´s a really good idea to use a block of plywood tu build the vanes. Love it!
Nice build! I look forward to the second part.
Out takes are the best part! Great job my young friend!
I really like the longer video and additional detail. Top quality video Marius!
Excellent video and absolutely entertaining. It's funny that I don't notice you rambling until you point it out! Very funny pointing out the critics. There's never a short supply! Good stuff, Sir!
Love the way those fins turned out. Accidental art.
we judge you on your failures not you success's , bold project. very interesting to watch...thankyou
"Not based on calculations, more on gut feel."
You are becoming a more seasoned engineer every day!
Good build so far! (The other blower was good as well!)
As an engineer, I refer to this as a SWAG: Scientific Wild Ass Guess.
A very complex project, also an awesome project. Well done as always. I have noticed (as you have) the trolls know how to make everything perfectly. Funny how we never get to see there postings. I guess they are to busy trolling. I look forward to the completed project. Thanks. Keep up the great work and thank you for sharing your skills and knowledge with us.
digitalradiohacker I understand your point of view. I would be sad if that happens, I don't have the skills and knowledge to make videos. But I do enjoy videos and I try to offer words of encouragement, to those who are able to make videos. As my parents said, if you can't anything nice, don't say anything at all.
“the trolls know how to make everything perfectly.”
People who have made stupid mistakes can only TELL you when you’re about to make your own.
We can’t STOP you from doing it.
“Experience is the worst teacher; she gives the test before you learn the lesson."
William Carr Thank you for the quote.
William Carr yeah but in this case nobody told him when he was about to make his mistakes, only _after_.
Point being that people werent trying to be helpful, just smug..
Excellent craftsmanship! I am a tool and die maker by trade, in business for over 30 years creating many incredible works art with steel dies. From F18 fighter jet parts to toothpick sorting machine. Here is a brain teaser. I had to cut make 100,000 keepers for the Canadian military. In order to be unbeatable in price, I devised a machine to cut 1.875" OD brass tube with .040" wall thickness to .375" lengths, WITHOUT scrap! These rings were then shaped into the keeper that looked like a dog bone. I challenge any engineer to come up with such a scrapless tube cutting device!
That gear puller is GENIUS, I've never seen one of those before! Great vid!
Another great video. I really appreciate the detail you go in to, I learn so much from you.
Something you might consider, though it is more work, is to round the leading edge of each fin and to taper the trailing edge. Through observation on small balsa gliders I've found that this improves efficiency greatly. It may contribute to lower noise or less power required or greater volume of air being moved.
Marius, when i saw ur joy when it fit together from first try i saw the thing only people who do woodworking feels :D
Hi Marius,
I haven't got a band saw so I have a problem with cutting the curved wings. I'm thinking of using 2 or 3 mm plexiglass, what do you think about it? Will it work, have you got any experience in this?
Why do you use the secend ring, it is necessary?
Don't use plexiglass, it's brittle and will shatter. The top ring is needed for stability (it's essential for a wooden impeller)
Thanks for your hints. I will use them while making my own dust collector.
Ich ziehe gerade orangenes Abflussrohr (KG-Rohr) für die Flügel in Betracht:
Die Rohre mit 250mm Durchmesser haben eine stabile Wandstärke von 6,2mm. Davon werde ich zunächst Ringe abschneiden und diese dann in Segmente teilen und als Flügel verwenden. Was hälst Du von dieser Idee?
Little by little this is becoming one of my favorite YT channels. You're pretty damn funny, not to mention smart as hell. Great job. I love the outtakes.
your work is incredible, clean design, beautiful made...congrats!!! ( by the way, a long video with all the descriptions and details is not a problem! is a pleasure ) you have a real teacher spirit, please go on.
I like your process of thinking and learning, as well as your...
HOLY SHIT, THATS A BIG FLANGE REMOVER
...as well as your process of showing and discussing your learning experiences. Your content and channel are great. Haters gonna hate.
Loving the details in your thoughts explained, very neat.
great video! and thanks for explaining what you were doing and why.
I don't care if its working, or if it will break up. I only care that you are trying and totally respect that. Keep up :)
Love it! I can't wait to build one with my CNC one day. The plywood worked great for the fins!
I would add that with a variable frequency drive you could tune your design to the highest possible efficiency with that blower wheel and motor. Again great work!
Wirklich, hervorragende Arbeit. Meine Hochachtung hast Du.
Its experiments like this and brains that explore - that allows humans to have cool stuff - keep progressing and cool video..big like my man
Great out takes, looking forward to part 2.
Helpful tip for bent plywood - it is possible to make your own ply using a form and then gluing the layers together - time consuming but you can get virtually any shape you want. Just have a reverse form on the top and clamp the whole thing tightly.
Please...... Do NOT use the steel key you made. Keystock is designed to be sacrificial..... to be the weak link..... and prevent further damage to more critical components..... Namely your impeller or your motor shaft. Here in the U.S. keystock is generally a zinc alloy and can be bought to size or in a 12" stick. Nice video. Very well orchestrated. Keep up the great work.
Dave Potts True, but that is for a steel shaft to a steel pulley or gear. his pulley/gear/blower is wood...it is the sacrificial peice.
If we buy keystock here its C45 - Carbon steel with .45% carbon. Same for keys that you buy seperately, those are also carbonsteel.
The key won’t break before the wood does, and when the wood breaks someone is going to lose an eye.
William Carr how do you suppose someone will lose an eye?
how, he has got a metal case?
Be open minded people this kid is awesome... keep up the good work man.
Elegant solution on the vanes Marius, they came out beautiful and look extremely durable. Some of my vey best Captain obvious statements are; That will never work!, or ; That's the first thing you check! Best response; I know that! (especially if it is total BS.) Enjoyable video, keep it up, cheers!
Like you, I have made things before I understand the engineering, in that case it is easier to make a prototype with its shortcomings and call it the Mark 1, the improved model will then become the Mark 2 and so forth .
Really impressive! You do great work, thank you for sharing!
Wow these videos are great.
*converts to freedom units*
Holy crap. 18"ish impeller?!? Impressive. Most impressive.
Fantastic build.
Commenting on the comments was hilarious. Of course you had to know that everybody is an expert on everything, except the original creator. Especially about things they never made themselves and even more so on things they couldn't even dream up on a good day. Evidently, of course :D
Don't let the keyboard warriors get to you, Marius. Your talent is over 9000 and these types can only aspire to be jealous of it.
But It's fun making fun of them.
Very informative design build video. At 13:00 glued up that way you would have a nice vase.
Du könntest dir eigentlich ganz einfach eine automatische Stern - Dreieck Anlaufschaltung bauen. Dazu brauchst du eigentlich nur 2 Schütze und ein Zeitrelaise für die Stern-Dreieck Umschaltung. Das würde auch deinem Motor und den Rotor auf Dauer gut tun.
Aber ich weiß, man muss schon einen faible für Elektrik haben, um so etwas praktisch und einfacher zu finden, als es momentan ist. ;)
Achso ganz vergessen: Echt gutes Video, mach weiter so!
Naja das ganz ohne anhnung von et zu bauen ist mit gewissem risiko verbunden, besonders bei knapp 400V die dir entgegen kommen können ^^
Selber bauen ja. Allerdings gibt es solche Controller auch fertig aufgebaut für die 35mm Hutschiene in jedem guten Elektrogeschäft (wenn nicht, im Internet) für recht schmales Geld.
Hat den Vorteil, dass der Rotor filigraner aufgebaut werden kann, ohne in die Luft zu fliegen ;)
Die Controller, die ich gefunden habe, kosten >200€. Kannst du mir mal ein Beispiel zeigen?
Ein Zeitrelaise kostet ca. 40€, ein einfaches Schütz auch. Aber am günstigsten wäre immernoch ein Handschalter.
Another enjoyable watch. Thanks for sharing.
Nice to see other young dudes proficient with tools and woodworking/machining. Its a dying skillset.
Excellent build Marius, I hope this blower will be more durable!
Love the detail you include.
I love your vids and your acomplishments. you seem to very good work with what you have and what I really like is that you dont mind making fun of yourself, and that makes these vids even more enjoyable. After all, we ALL make errors. keep up the good work
For a blower a soft-start is a good idea, less mechanical shock at startup. And the power goes up at the square of RPM for a blower so you don't need a VFD for constant torque (unless you want to have closed loop control, but you most probably don't).
Definitely keep explaining why you do things the way you do them.
Great vid Marius! You always have me laughing while learning along the way. Keep them coming!
Excellent video. Excellent explanations and reasoning.
I can recognized a clever person when I see one. So, yes, I have subscribed.
Great video as always! I have to express my doubts about the plywood fins though. Cutting them the way you have means that the grain is on average at about 45 degrees to the force. I can see this causing the laminations to strip apart after sometime. No way to know for sure without trying it though.
Awesome video, youre a genius. I'm gonna try and make a mini dust collector in the future like yours and also the table saw work station. keep up the good work!!
Everytime something goes wrong TH-cam suddenly full of experts on the subject.
Watching your video for the first time, and really liked it. Love the way,how you are explaining stuff (problems and creativity). Keep doing the good work. You're awesome , Dude, really inspiring and educative. ;-) God Bless.
Regarding the thickness/weight tradeoff for the second plate, you could also consider a mix of thicknesses. Use the 12mm plywood, but route away material in less crucial areas. Just something I thought of and thought I'd mention.
Good work! I love your out takes. keep them coming!
What the...?! I sit and watch this video at 4 am and then I don't get to see the finished thing? I need to see that NOW!! :)
"Shit" 😂 Love how chunky the bearing puller was that you found in the bottom drawer!
Good and professional work!
Excellent video (as usual)! Don't forget to balance the impeller (like Matthias did in his video). I also agree with Matthias on the thickness...
+Lance Bledsoe I did the balancing in the next video
OK sorry I spoke too soon! Where do you live? I have been to Germany a number of times - Munich, Frankfurt, Hannover. I'm in the computer biz and used to go to Hannover fair every year and my company had it's German Office in Munich, so I've been to Munich a lot! I LOVE Munich... I can't remember meeting any of the German people who were not extremely nice and welcoming of Americans! October Fest in Munich was a real hoot! :-) Keep up all the GREAT videos!
Love the combination of woodworking, precise and simple designs (how very German) with great humor (I didn't know Germans were this funny). Great troll smashing too.
Wow, something TH-cam recomend me that i actually enjoy. Subscribed!
Excellent video! I really enjoyed watching it, and also enjoyed the bloopers at the end haha!
love the detail, love the journey and the revelations as you noticed the mistakes.
I'd hate to think of how much money you've spent on tools and stuff :0
looking forward to your other videos now.
one bucket of thumbs up for you good Sir!
If you are having fun, and doing your best....keep laughing at the haters..... Don't give up.
I love your videos, fun and engineering all in one video
I really appreciate your amazing job, thanks for sharing, keep going
To reduce the startup jolt, in the past, I have used a cheap Chinese clothing iron. Electrically, put the iron in series with a switch across it. At startup the iron will limit the power to the motor. Once at speed, throw the switch that shorts out the iron. For smaller motors, a incandescent globe can be used. Cheap, simple, maintainable, and can usually be done for under $10.
Last 2 seconds was really funny! LOL!!! Nice video! Thank you Marius!
I don't even know why I'm here or what this is for but its entertaining
Great video! Your language skills are excellent, and by that I mean your ability to explain things clearly and succinctly. Your English is also excellent :)
Thanks!
Absolutely brilliant.
