Dust Collector Update & RODE WIGO Charging Station (Random Shop Stuff 24)

[@yummboy2]

Regarding a possible video about a new impeller, I vote yes.

[@martin_hansen]

Like to see that too. What i also would like to se is if you include a factory made version (plastic/metal), in the comparison. Not that i do not see the fun in making your own the comparison would still be interesting.

Marius: Makes amazing charging station for his Røde mics. Røde: 1 year later, comes out with an identical charging station.

[@breakinn403]

Thanks for the update on the dust collectors. Obviously well engineered and made. They will be in service for many years to come. I love the mic charging station. Amazing how you designed and made them. The band saw project is finally put to bed. Time to move on to another project. We eagerly await for it. :o)

[@MRrwmac]

Marius, great proof that your dust collector designs work extremely well.

[@MariusHornberger]

Thanks

[@FesixGermany]

9:13 The pose tells us exactly what was in your head

[@3dmazter]

When the dustbin is 100% airtight you can use a dustbag inside. I have a metal bin with a bag and that works perfect. Just put a fee pieces of scrap wood on the bottom for weight. You can epoxy the osb to make it airtight or use PU

[@letsflywiththemusic]

Also, the dust collection system will only operate at it's maximum possible efficiency when the bottom section is completely airtight, so this should be done anyway.

[@bradley3549]

Alternatively, or additionally, he can provide bypass air to help balance the air inside and outside the bag.

[@3dmazter]

@@bradley3549 He already tried that with a air hose from the cyclone to the bin to keep a vacuum outside the bag but it didnt work.

[@bradley3549]

@@3dmazter I must have missed that one. The concept does work, I have done it. As usual the devil is in the details, I will have to look back to see what how he did it.

[@dan__________________]

To solve the issue of the bag deflecting in the dust bin, you can insert an open ended cylinder inside the bag that holds it to the outer wall of the bin. Mine is just made of a sheet of puck board riveted into a cylinder shape. You then slide the cylinder out of the bag before throwing it away. This, however works better in a cylindrical bin and not a square one.

[@gregmislick1117]

Marius - For the band saw cooling .... simply add a motor housing and a cooling fan - you could probably just put a dust port on it and use the big blower to suck air over the motor - this gives you the option to use auxiliary cooling, or just the built in fan. No need for new pulleys

[@Wordsnwood]

Just received my Rode WIGO yesterday and really looking forward to trying it out... I'll keep that charging station idea in mind, thanks!

[@NBCRGraphicDesign]

Thanks for the great technical dialog about your design process.... very much appreciated. Also, your discussion about how Germany handles trash is very interesting as well. Here in the US our garbage is *mishandled* much differently. Please tell us about your current studies at school.

[@hpda44]

Great video. I especially liked your discussion of the prototype stages in your design process.

[@Balsamancnc]

I regularly run my 1750 rpm motors (lathe, drill press, milling machine) at twice that using a VFD and never had a problem. They would much rather run fast than slow. Another bonus is you don't have to deal with the lack of torque that comes with running at low frequencies. So a low gear ratio coupled with high frequency results in high torque and decent top speeds.

[@ArtturiSalmela]

That charging dock is pretty clever

[@MariusHornberger]

Thanks!

[@Bristoll170]

Very common for induction motors run at slow speeds, is to remove the motor fan, and fit an auxiliary cooling fan in its place.

[@dyingsanity3252]

When that day comes and you fly the coup, I hope the house you buy is a real fixer upper. I'd love to see that progress.

[@JoeMalovich]

I've also been working on a dead cat holder for my same microphones since I work outside a bunch. The dead cats fall off way too easily.

[@theonlyari]

The areas of collection on your impeller and inside the separator are absolutely due to the low pressure, as you mentioned, but also static attraction. The dust is charged. Since your parts are made of plastic and wood (with a plastic finish layer on the outside) it will become charged over time and attract dust. There probably isnt much you can do. Maybe adding a ESD discharge wire to your ducts, if you dont already have one, might help-- but i doubt it.

[@dennismartin3508]

This kid is amazing!!!!

[@bradley3549]

Another food for thought with the motor RPM with the VFD is that you could also install a thermal switch in the stop circuit that would trip off the VFD when the motor became too hot. This would be a good idea regardless of whether you adjust the pulley diameter. I suspect you would be fine with the current pulley arrangement since you're not running the saw for hours on end.

[@benjaminjohnson6476]

From what i understand of aerodynamics and bernoulli's principle is that and gas that accelerates has a lower pressure. So the front of the impeller blades would actually be a lower pressure as opposed to the higher pressure described. I would imagine the dust build up is actually from a buble of stagnant air that sits behind the blade as it runs much like when you move you hand fast through water and an air pocket forms on the back side of you hand.

[@3dmazter]

Just install a big pc van on the back of the motor. You can controll it with the VFD. It has output for that and you can change settings so the fan only starts when you go below a specific motor speed.

[@edwardholmes91]

I was wondering the same thing, although I didn't realise that the VFD had an output for this, I thought that you'd have to design it yourself.

[@warrenneeves7103]

I had a similar heating problem going to a VFD. Easy fixed with a computer cooling fan that runs when the VFD is on. I took off the original fan and modified the housing to make some space.

[@colh5910]

I think you should run the dust collection system out through the wall into an adjacent shed or outbuilding. Cleaning would be easier and safer on your lungs. Is that feasible? Regards Col.

[@arnearne12345]

HEY quick idea might be crap BUT i think you might be able to make an adapter that allows you to attach a red bag to the second dust collector you emptied in this video relatively easy that would allow you to minimize cleanup while emptying the bins and it would also compact the sawdust quite well

[@MariusHornberger]

Hm, could work. My idea would be a big funnel

[@arnearne12345]

@@MariusHornberger definetly harder to store unless you make it collapsible

[@toastbr0t]

22:20 Very clever solution :)

[@MariusHornberger]

thanks

[@Tiger90Drake]

Interesting topic! Instead of worrying that the motor might be getting too hot when you run it at 30 Hz for a few minutes I'd rather be worrying about it overheating if you run it at 70 Hz or more most of the time. Unless your motor is rated for that kind of speed (which I doubt) the coils will get hot and the lifetime of the bearings reduced. Personally I'd prefer your first option (50 Hz for wood, less for metal).

[@micbanand]

if you have the opportunity to shift fases on the motor or other metod. you could make it run backwards for a few seconds after daily use. cleans the fins quite good :)

[@MariusHornberger]

Neat idea, but I can't do it with this motor

[@ItSeemsDark]

17:35 yep , it would be interesting indeed :)

[@creative_stwb1336]

Das Problem mit Motoren und Frequenzumrichtern wie du bereits erwähnt hattest ist Kühlung. Ein Probleme was du nicht Bedacht/wusstest ist das Motoren die Über der auf dem Typenschild stehenden Frequenz betreiben werde an Drehmoment verlieren da sie im Feldschwächebereich betreiben werden. Der Drehmoment Verlust kann bis zu 60 Prozent betragen je nach Motor. Ob das dann noch reicht um zuverlässig Holz zu scheiden musst du selbst wissen oder probieren. Ich persönlich würde eher für eine Fremdbelüftung am Motor sorgen als ihn bei 70 oder 80 Herz zu betreiben. Zum Thema Stern/Dreieck musst du schauen was auf dem Motor Typen Schild als zulässige Spannung für den Stern oder Dreieck betrieb steht, sowie die Versorgungsspannung deines Frequenzumrichters beachten

[@Moksoory1]

[@theDaftman]

remove the motor fan and replace it with an electric fan, incorporate a bit of electronics (Arduino) for speed control, slow RPM makes the fan speeds up keeping it cool regardless of speed of the drive motor. (The DM UK)

[@digitalradiohacker]

Ha! I just commented pretty much the same. Add an LM35 temperature sensor to one of the analogue inputs, and you could have dynamic fan speed on the basis of motor case heat: ~ Not very hot? Fan speed low (quiet) ~ Getting toastie? Fan speed high (removes more heat) I've always disliked having fan cooling attached to motor shafts.

[@DesandSam]

Maybe you could use your dust collector to draw air across your band saw motor, perhaps build an enclosure to guide the air.

[@fuzzy1dk]

you could use the dust collection to cool the motor when cutting metal

[@cityguyusa]

Put a note on the small impeller why it's hard to take off so you remember.

[@dasistdochsuper1]

Regarding noise, try using different blade distances. (Like it is done in tyres and cvt chains)

[@piratmitholzbein]

[@tommiestrydom973]

I use my sawdust in the garden as mulch

[@musicbymark]

8:46 I think you could put a (large enough) plastic bag OVER the dust can, keeping it tightly around the can, then invert it upside down; if your red bag isn't big enough to go over the dust can/bin, you could use a different trash bag to dump it in first, and then put your red bag over the opening, dumping the first/larger bag into your red bag OUTDOORS. :-)

[@smash5967]

For impeller design, this wouldn't work with 11 fins, but it would be interesting to use a design with different length fins. That should spread the noise across a wider spectrum making it sound quieter than it actually is.

[@calvingreene90]

The first solution to the motor overheating problem that sprang into my head was to use the dust collector to suck air through the motor.

[@digitalradiohacker]

On the bandsaw, pull the silly bent piece of tin that "they" call the fan off the motor shaft. Vanish their silly restrictive cowling. Replace it all with an electric fan. I'm sure you can come up with a cowling / cover to pretty it up and make it safe. If the cooling is done separately with an electric fan, the cooling will obviously be separated from the motor speed. I'm not sure if it is the kind of thing you want to get involved with, but you could even have dynamic fan speed control on the basis of motor case heat. A microcontroller and a linear temperature sensor like an LM35 would do just fine. Horses for courses I guess - You might prefer the mechanical approach.

[@alfredneumann4692]

Name the part 'mounting-foot'. or so :-) Bandsaw: I guess, it's easier to mount an independed fan behind the motor. They are available in 230V, so you don't need a powersupply. And they are cheap. But use one from Pabst. They have have good bearings.

[@Kaerugreen]

Hi! Love your videos. Can I ask what software you use to design your models in for 3d printing?

Red bags in America are often medical waste (bio hazard) of some kind and are only used in medical setttings. I wonder what color you all use for that.

[@la6496]

Hallo Markus, Kleiner Tipp von mir für den Staubsammelbehälter: Am Boden eine Rasterplatte dann einen dünnen Schlauch 10-20 mm unten am Raster einführen und als Bypass zur Turbine anschließen. Dann kannst Du problemlos einen Beutel einlegen, natürlich oben befestigen. Diese Vorrichtung sorgt auch für Unterdruck außerhalb des Beutels, so dass dieser nicht mehr nach oben gesaugt wird. Habe diese Lösung früher öfter verkauft, könnte Dein Problem also auch lösen. Grüßle aus dem Ländle Lothar

[@MariusHornberger]

So hatte ich das auch mal aufgebaut (siehe ältere Videos) hat aber leider nicht funktioniert. Wahrscheinlich weil ich damals den Schlauch an der falschen Stelle angeschlossen hab. Wo genau müsste der Schlauch denn hin, direkt am Gebläseeinlass?

[@la6496]

Marius Hornberger vor dem Filter, aber ruhig nach dem Zyklon, dann bist Du auf der sicheren Seite wenn der Sack mal reißt. Wichtig ist das Raster am Boden, damit der Unterdruck überall hinkommt. Welchen Schlauchdurchmesser hast Du genommen, bei Volumensaugern(also weniger Unterdruck) muss er etwas größer sein, da reich nicht ein Schlauch mit 10 mm Außendurchmesser, weil sich dann kein Unterdruck im Sauger aufbaut. Außerdem sollte der Kasten natürlich dicht sein😉 Grüßle

[@MariusHornberger]

Das war ein 1 Zoll Gartenschlauch bzw. sowas in der Art. Wenn du willst kannst du dir ja das alte Setup in den älteren Videos zur Absaugung anschauen und mir sagen was falsch war.

[@la6496]

Marius Hornberger werde ich tun.

[@la6496]

Marius Hornberger Hallo Marius, habe mir gerade mal das ältere Setup angesehen, der Bypass war definitiv an der falschen Stelle angeschlossen. Die richtige Platzierung ist bei Deinem bestehenden Setup auch sehr kompliziert. Du musst in dem Schlauch ja einen Unterdruck erzeugen daher musst Du nach dem Zyklon und vor der Turbine den Anschluss herstellen. Das heißt es muss noch ein Anschlussverlängerung zwischen Zyklon und Turbine, so ca 5-10 cm und da muss dann der Bypass angeschlossen werden. Ich hatte vorher nicht beachtet, dass Du die Feinfiltrierung nach der Turbine hast. Ein Setup das ich so nicht verwenden würde. Der Feinfilter käme immer vor die Turbine, damit durch die Turbine nur saubere Luft strömt und keine Partikel die Turbinenschaufeln beschädigen können. Hoffe ich konnte Dir damit weiterhelfen. Grüßle aus dem Ländle Lothar

[@cooperised]

12 vs 11 blade comparison, yes please! I've often wondered if it would be possible to figure out a nonuniform blade spacing that retains balance, too. High quality endmills sometimes use nonuniform flute spacings to reduce chatter, which is kind of related (avoiding resonance).

[@chrishb7074]

Non-uniform fans for reduced vibration? like the fenestron on the tail of an Eurocopter (now Airbus) EC135 helicopter.

[@myrthenboermann5979]

Heeyy Marius, is this KZbin thing your main job? Or do you something else for making a living? You spend a lot of energy in this and I really adore your videos. Big smile from your Dutch fan

[@jammi__]

Why don't you use a separate fan for the cooling? It'd be a clean, neat solution independent of the VFD.

[@Brauma54]

Could you compress the sawdust into pellets and burn for heating the shop?

[@erik....]

You will also get full power from the motor above 50hz, but not below.. So that is a factor as well. The power curve goes from 0% power at 0hz to 100% at 50hz, then 100% above 50hz as well.

[@ToxTox]

You lose torque when motor is going over nameplate speed

[@erik....]

@@ToxTox yes but not horsepower

[@peter2327]

What about screwing a electric fan to the cooling cowl of the bandsaw's motor? So that the big motor does not cool itself, but is pressure-cooled from outside?

[@inotoff]

I always appreciate the fact that you show and assume your mistakes. It's very relatable :)

[@markn2904]

Could it be the cracks you are experiencing on your motor, is from the torque of the motor when it starts and stops?

[@YamahaYZFR6RJ05]

bring the sawdust to a horse stable somewhere near. as i worked as a carpenter some time ago we did that every two or three weeks and the owner was quite happy about the free stuff.

[@MariusHornberger]

[@steffen1182]

Hi Marius! Along the years you've made at least two variations of dust separators with Thien baffles. Which one do you think works best for a shop vac set up considering use for finer dust mainly (track saw and sander)? The one you made for the pantorouter ou the other for your dust collector?

[@avivgg6421]

hey Marius, in minute 28:10 when you spoke about the motor cooling problem, you should not have a problem since the VFD limits the voltage and current that the motor takes, so less power less heat. some VFD's have a motor temperature protection feature so you should check about that. if it doesn't have that feature then you can design a protection circuit. if you need some help Ill be more then happy to assist you even thou I believe you'll be able to do that yourself and I also believe you don't realy need to worry about a motor heating problem.

[@MariusHornberger]

The VFD has heat protection built in

[@Kris_M]

@Aviv GG Lower rpm does not equal less heat. The same torque at a lower rpm requires virtually the same current. Per R.I² we can conclude that the amount of heat energy remains equal, while at the same time cooling is reduced by the lower rpm of the cooling fan.

[@censeless24]
