hffcom Thanks. Me too when I made my cyclone for the Shop-vac. There's a big silicone mess!

Marius Hornberger would something like the heavy metal foil tape used for duct work be more easily put in place there to seal the seam? (taped as smoothly as possible to the INSIDE of it....)

Thanks for the response! Gonna try that someday.

The more suction you have on the outside on the bag, the more the bag will try to expand. As dennis binyon said, 'equalise' is an important keyword. The more air-tight your chamber is (eg. the outer box containing the bag), the less the bag will contract. Imagine that air is sucked in from the outside through a hole in the bottom of the cabinet, then the bag will easily contract. Changing the direction of the same hole in the bottom would help avoiding it; the more suction, there, the better. Think about it and make a few drawings on a piece of paper; I'm pretty sure you'll get this right!

neelode I thought about that, but my camera can only record up to 30min... I would need a time-laps camera for that to work properly.No, I didn't measure anything. Maybe I build a manometer in the future.

Marius Hornberger COME ON, Marius, we're talking here about a demo of the suction of your cyclone, or something along those lines, not a feature length film. How long did it take you to suck up the sawdust? A minute or so? Likewise with the other things you did in your 10 minute video...

Thank you, new videos coming soon!

For acryllic you will only need water, but for silicone you'll also need soap (and try using gloves if you can, because silicone can't be washed off of your hands, you have to scrape or sand it off; gloves saves you so much trouble).

massoud147 Thanks!

Thank you very much!

+T Radford These filters are great. Find them here: www.amazon.com/Fellowes-HF-230-AP-230PH-Purifier-9370001/dp/B0067D7CSC/ref=sr_1_3_a_it?ie=UTF8&qid=1457706542&sr=8-3&keywords=hepa+fellowes I covered this filter topic in more detail in a newer video here: kzfaq.info/get/bejne/qrh1gLWjnZfTnJs.html

Thanks Marius, you're a star!

+Sergiy there is no "absorber", but the pipes have rubber seals, that absorb some of the vibration.

Yes, a little bit. But dust from sanding with 400 or higher still gets through

Grenade Gaming Thanks, but no. There are no plans available.

Marius Hornberger Thank you anyway.

Thank you! I didn't learn woodworking and I also didn't have any woodworking lesson. A lot " learning by doing". I also watch a lot of other KZfaq woodworkers and so I could see some projects and techniques to try out myself.

No. But it saved my filters once when I forgot to empty the bin.

Ich hab ihn so luftdicht wie nur möglich gemacht, aber er ist wohl nicht zu 100% dicht.

It's a proxxon

Suburban Pjokk ii

yes

Marius does cleaner work.

I see Marius and Matthias as being two very different people. Yes, they both do awesome woodworking, but I'd rather watch Marius' videos, because he's paying much more attention to safety, plus he has much more inner peace.

neelode Makes sense, but building this contraption would take several minutes and holding it only took one minute.

***** In Europe you can only get motors with ~2800 rpm because our power supply runs on 50hz. American runs on 60hz. I need a bigger blower.

You can maby try to build a gear to step up the speed. You can also try a DC or universal motor and then you'll get very high speed. You did a very good job! :-)

Gracias y saludos desde Alemania

amigo, sube tutoriales con subtitulos en español :)

lo siento, pero mi español no es bueno. La mayor parte es sólo Traductor Google...

+Stefan Asmussen not enough space for it.

50 liter kann man ja auch kriegen :)

neelode It takes time to setup the router. The scroll saw is always ready to use. I also wasn't sure about the exact inside diameter and once the pivoting point in the middle is missing, I can't use the router anyways.

+Gaston Laidano Si hay unos respuestas puedes traducir ellos tu mismo con Google translator. The commenter asks how the spiral and the filters function.

¿Cómo te va? ¿Ya aprendiste inglés? Es una suerte que Marius hable inglés, porque es alemán. Ja

leopard3c Hier: www.toolovation.co.uk/product_p/gb.gluebot.htm

Danke für die schnelle Antwort. Ich hatte da auch schon mal gekuckt, aber leider ist es da ausverkauft.

Jesper Hansen Thanks, but KID!?! I'm a little bit too old (20) to be called a kid. ;)

Marius Hornberger Young man, you are well beyond your years in knowledge. At 20 you are 2.5 times younger than me so "kid" fits by age but in no derogatory way....I think Wiz Kid is more appropriate ;-). You are doing excellent work in your shop and with the videos. Much appreciated! Question: Are you currently attending University or are you one of those who finished college before most people finish high school ;-). Cheers from USA!

Well, thank you very much! As I'm from Germany, our school system is a little different. But I passed my "Abitur" (A-levels) with 18. Right now I'm waiting for my place at university.

Marius Hornberger Congratulations! You will do very well. Good luck with studies and continue your woodworking/creating passion as well. I can all tell how much you enjoy working in your shop!!!!

Interesting idea, but unfortunately I don't have the equipment to try this out. It is just an oversized impeller in an undersized blowerhousing. Just need to make a bigger blowerhousing.

Marius Hornberger you could try the trick Mathias Wandel does on his channel with the blower he built....try holding various cans & containers of different sizes across the exit. When you find one that's the right size, it'll create a counter-resonance and reduce the noise significantly

Tim Hyatt That's not possible for me, because my filter unit is there.

You're right. The disaster also happened, I made a video about it as well.

Please explain! 😱

+michaS Silicon is an excellent adhesive in the right situation...

+D Nesser Nice for postage stamps, perhaps not much else. The rotor vanes that Marius made were secured with what appears to be a PVA glue, that too is a relatively low performance adhesive. For engineered applications an appropriate spec epoxy adhesive is far better. Given the overall high standard of design and execution, I am surprised by the choice of silicone and PVA. The response, 'they are good enough' clashes with the attention to detail and precision we see otherwise throughout the project.

+Robert Seviour Ha! "nice for postage stamps" ...Sir you don't seem to know what you're talking about. Like I said before Silicone is an excellent adhesive... I'm sure you've seen a glass Aquarium? Well those panels of glass are "glued" together with nothing but Silicone. I personally have a 75 gallon tank built in my wall directly above all of my home theater & stereo equipment, a lot of $ under roughly 1000 lbs of glass, water & rocks. I've seen way bigger tanks all built with silicone (glass not acrylic) I've been an architectural woodworker professionally for over 20 years, hence the reason I stumbled on this video, looking to maybe beef up my dust collector. I only use Silicone to install inlayed granite or solid surface materials in wood, because I'm sure you already know wood expands & contracts therefore I need the flexibility of the silicone. I would love to see you try & remove one of these granite of marble inlays without breaking them and I only use a few dabs of it. As far as the "PVA" glue or you could just call it what it is, wood glue he used for the rotor vanes, perfectly suited, there is no need to waste extra time & money. The title of this video is "Homemade Dust Collector" and I think he did an Excellent Job!

D Nesser There are many 'wood glues' starting with boiled down horses' hooves, then casein, then the first synthetic glues, such as those based on formaldehyde, latterly PVA and for engineered construction the range of epoxies. I have used all of these over a span of approaching 60 years, so I do think that I know what I am talking about. While it is true that you can bond glass and some other smooth surfaces with silicone, it still far weaker than epoxies. Furthermore if strength matters for wooden construction, the material should be dry, and kept that way by complete encapsulation in a waterproof coating. For this an appropriate epoxy is ideal. I ran a business supplying epoxies to boat builders making from canoes to ocean-going trimarans. There's a lot of literature on the subject if you would like to learn more. Start with 'The Gougeon Brothers on Wooden Boat Building'. Whilst I agree that Marius did an excellent job, his choice of MDF and PVA adhesive for the vanes leaves a lot to be desired considering the large forces produced by the high RPMs. Considerably better - and without costing any more time, perhaps even saving some, would be to make a laminate construction with thin ply, glass cloth (or carbon fibre, and you wouldn't need much of it) with epoxy to bond. That's the way high performance components are made from jet planes to skis. That would obviate the need for the buttress strips Marius used to support the vanes, and lead to better aerodynamic performance.

+Robert Seviour I apologize for underestimating your knowledge of glues & especially "Epoxy's" I never said silicone was better in any way, I simply responded to the original comment that it IS a good adhesive in the right application... Google It. I am well aware epoxies are great for certain applications... I spent $500 on an epoxy mixing gun for fabricating solid surface material that now just hangs in my shop because everyone wants "real" stone now. I work for a small family company that builds Banks, my uncle owns, my dads the architect & I'm the cabinet guy... from the design to the finished product... there are many glues, epoxies, adhesives, sealants etc. that go into a structure. To me you sound a little biased towards Epoxies, having been selling them your whole life, you sound like the sales people that come into my shop trying sell me "Better" sandpaper than I'm using cause the glue holding the agragite is better, it never is.... & where did boat building come into play? and yes most people probably know that moisture isn't good for wood, in fact the moisture content of the wood plays just as much of a role when "gluing" wood.. we're talking about a homemade Dust Collector here! I doubt he had fiberglass or carbon fiber just layin around, it looks like he's using off fall & scrap wood to build it. If you've got a better design make a video & post it.

Ja, bin ich.

ja ich mir gerade auch bei dem durchschauen deiner Videos aufgefallen. Der 1und1 Router hat dich verraten ;) Kommst du aus dem Westerwald?

Simon Gerharz Nein, das Allgäu (am Bodensee) ist meine Heimat

Schade 2,5 Std. von mir. Schöne Bandsäge hast du da. Die ist auch nach dem plan von Matthias Wandel oder?

Ja, ist sie und läuft ganz gut
