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

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)

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.

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

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.

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

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.

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

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

15:49 wenn du dir dein Video anschaust, wo du den Motor verbaut hast siehst du, dass der Motor die Risse von Anfang an hatte

22:20 Very clever solution :)

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).

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

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.

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.

Diese Kunststoff Lüftungskanäle (der Weiße mit dem Konfetti) sind aus PVC das heißt man kann die Mit Tangit PVC-U Kleber kleben.

There may be companies that will buy your sawdust for something like particle board. Much better than putting it in the trash.

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.

that is an amazing fertilizer.why dont u spread it on soil?

The question I have is why not take the cans outside to empty them, then nature can do the work of clearing the air. Otherwise your design seems to be doing brilliantly.

@8:16 why not put bag in bucket. Then emptying bucket takes 3 seconds, instead of transferring it to a bag. It's already collected in the bag.

Heeyy Marius, is this RU-vid 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

29:40 why not just adding a electric fan to cool the motor?

If you're into Mycology all of that sawdust is a good source of material.

Hello from Mexico Marious. Do you know what happened to Chris’s Chanel. I started to follow him but he haven’t post any content in so many years.

20 minutes for my comment? Now I kinda feel bad 😅 But very interesting! I would love to see a video about a 11 fin design. Maybe only do 10 fin? You might not be able to tell the difference with such a small change, going from 12 to 11 - But I don't know. I'm not an expert.

The bucket on the small dust collector might should have one of those bags in it... Right? Also, I bet your mom could make and sell those sleeves for at least $20-25 USD... Maybe even more, since I legit thought that was a thing I could buy.

Wäre dankbar, wenn du mir einen Link zu den verwendeten Filtermaterialien geben könntest. Das mit dem umgefallen Sack ist normal, da haben wir uns bestimmt alle schon dran übernommen :)

besorg dir doch einfach einen zusätzlichen motor lüfter für die Säge oder bau dir einen selbst aus einem Toiletten abluft lüfter oder sowas in der richtung

9:05 Sorry but I laughed so hard :D

I didn't know that rode made a wireless laptop mic. I can't find 1 on Amazon

Why don't you use the sawdust for garden mulch?

Can't you control the fan separatly? I think it take power from the motor supply but you could give it a separatly source

For all the things you make, we all know that you created them unless you tell us that you used someone else's design, but you always tell us. You come up with some really good designs.

Dude you should have patented it while you could

Oberhalb von 50Hz wird der Motor an Drehmoment verlieren, die abnehmbare Leistung bleibt jedoch konstant. Wenn dein Umrichter um Faktor Wurzel(3) größer ist als der Motor kannst du den Motor in Dreieck(230V) Schalten und an dem 400V Umrichter betreiben. Natürlich muss man den Umrichter entsprechend parametrieren! Das bringt den Vorteil das das Drehmoment bis zum neuen Eckpunkt an dem die Spannung nicht weiter erhöht werden kann konstant bleibt. Das wäre dann bei Wurzel(3) * 50Hz = 87Hz. Sprich aus dem 1,5kW Motor wird damit ein 2,6kW Motor bei erweitertem Drehzahlband! Wenn du weitere Informationen brauchst such einfach mal im Netz nach "87Hz Kennlinie" Oder schau dir das Dokument von Siemens an: support.industry.siemens.com/cs/attachments/25338130/25338130_Betrieb_von_Motoren_mit_hoeheren_Frequenzen_v2_1_de.pdf Das ist wirklich eine gute Möglichkeit da mehr rauszuholen. Von der Umrichter Auslegung geht man da am besten Anhand des Motorstroms im Dreieck Betrieb.

Germany uber alles

4:28. You made your own air filter with a metal frame and pleated paper? Jeeze that's smart. I am feeling so stupid now, compared to all the things you've designed. The ingenuity of dust collection systems on RU-vid is above any other thing. If men could apply their dust collection technical knowledge to solving world problems, there wouldn't' be any problems. 8:45. You legitimately could have a copyright infringement claim. If you published a video about your dust collector, published work is copyrighted, automatically. So you have copyright law. You could potentially make millions on a friendly lawsuit. They do deserve to pay you for exactly copying your design, which it appears that they did directly copy you. I think they'd be happy to pay you.

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

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

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

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

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

hier in Hessen ist das Müllsystem wieder komplett anders...ich glaub das ist in jedem Landkreis unterschiedlich

I went and watched how you made this back in 2015. (Small Dust Collector #2) you can see the motor already have cracks where you indicated in this video.

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

Very interested in a performance comparison of impellers with different number of vanes. Hope you do that video.

Nice vid, unsubscribing from all makers who use mid roll ads. Went back to view some of your old vids which are now un-watchable because they are riddled with adverts ever few minutes. Why would you let the tube ruin your content like this?

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)

OUTTAKES: /Dust bin emptying goes right into the red bag/ "aw, shit, now I have to empty it again so it spills, dammit"

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.

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.

For the red bags, you could/should use a holder, that keeps it open and upright for you.

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

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

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

Marius, the motor issue, keep it simple, just add a standolone fan on the back of the motor. While ICE engines need temperature to work, electric motors hate it. I don't know how much cfm it would need, but something physically identical or more efficient than the one attached to the motor. Running the motor above 50hz, will produce a tonload of heat... I wouldn't do it.

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

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.

Hallo Marius, der Versuch mir den 11 Schaufeln wäre sehr interessant, vor allem, was die Unwucht angeht, bei 12 sind immer 2 Schaufeln gegenüber, bei 11 Schaufeln gibt es da einen Winkelversatz. Wie stark sich das auswirkt, wäre wirklich sehr interessant. GLG Jochen von JoJo's Workshop

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.

In Sweden (atleast the part where I live) we pay per kilogram of waste.. The garbage truck scans the bins and weighs it automatically before and after emptying. Unfortunately the yearly fee is quite high compared to the fee per kilogram so it doesn't really promote recycling as much as it could.

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?

Why paid to get rid of the saw dust? You can use that money to buy wax (if you have good relation with the church, you can get candle butts free). Pour melted wax into saw dust and you get blocks of solid fuel, all you need is just a silicon cup cake mold. Those solid fuel can be use in campfire or heating in winter. If they are all coming from natural wood, you can also use it to cook.

that garbage system is sensible, ours here is the full size box that you have, each week they empty it, we do have recycling but its not enforced really, every second week they will pick up paper recyclables, we have to bring plastics to a depot ourselves. For bulk (ie old furniture/appliances) once a month there will be a day you can request something to be picked up.

Thank you for verbalizing your design process. I found it very useful.

8:50 - The ghoasts of historical woodworking projects being sucked away to a dark, distant place.

Nice to know somebody's taking a concern about health in your industry the date is out there and people on RU-vid just blase about it, do you have a particle metre to measure how much is in the air? Wood fibres paper fibres should be treated as a specialist and the workshop should be like a medical Theatre Not necessary to waste the sawdust you can make it into logs and sell them or use them or make it into furniture again mixing in epoxy making sheets What about a water filter system ever thought about doing that it's the best filtration for small parcels Can't you lacquer the impeller with a water-based acrylic and polish it. or at least rubbing the impeller with candle wax and polishing it. And man some beading on the inside of the Impaler you getting airflow problems with swirling vertices maybe building adhesive or corking you stuff about half an inch across on the edges Why can't you just put the bag inside the bucket put it over the lip of the bucket and have a big lastic band holding it please or bungee cord, or piece of string Only have to do is release the elastic band and Tie the bag at the top maybe some draught excluder around the top of the bucket so the bag has soft padding and round the corners of the bucket over on its outer Edge Do away with the corrugated paper filter and use a poly finder harder to clean I grant you would be better needs to overlap the edges of the filter I think as well Yes I think the impeller might be heavy and and out of balance even if you got till the vibrations you could have used forgot the name of it thin veneer plywood with a foam interior sandwich it would be good I don't know if it is on your impeller to make the impeller slightly narrower on the outside inlet than the inside that increase the vacuum just a couple millimetres narrower. Yes that sounds about right a low pressure maybe as you say static build-up because it's plastic PVC try some copper tape around it Earth

I wish our refuse service was as sensible. Buy a 'pre-paid' bag from them for a reasonable price. Then when you have more trash, you have a solution ready and waiting.

I went back and watched the building of your dust collectors. I can answer the question of where the cracks in the housing came from; Ebay. Your motor came pre-cracked.

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

in canada we cover the bag and than lift the bin up side down and slowly pull out....just joke.

Wow. Your post this time is fully packed. Lots of ideas for us to see. Thank you.

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.

I am wondering what your profession is? You can’t do full time on RU-vid or live of your shop?

I'm wondering if there's a way to make a dust collector that compresses the waste into fire logs. Especially one that fits under the cnc machine. You can use them in fires or sell them.

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?

Do you have a video showing how you made your CNC dust collector, the smaller one? I'd love to see how it actually works. It appears that you put the impeller above a cyclone tube, which makes the system more compact. But if I'm seeing it correctly, you could locate the impeller and motor assembly across the room and still use the dust collector, as the impeller isn't actually acting like a centrifuge correct?

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

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

1:10 - Archeology for woodworkers! Also, if the airtightness of OSB is a concern, paint is an easy way to improve that. :)

That charging station is really cool. Super compact.

Always a great & informative video Marius. Thanks, again, for sharing....

Looks like you need to enlarge your workspace for such a big dust collector system

To minimise the dust sticking to the plastic pieces, would it be possible to use earthing strips to remove the static?

Marius - I love your brilliant mind and wonderful projects/masterful videos, but I wish you were more green-minded w/ your woodworking, disposing your sawdust/shavings into COMPOST. I put mine in the garden, sometimes mulch plants with it, and sometimes burn it in cardboard boxes in the fire/woodstove like Matthias Wandel.

Too bad those red trash bags aren't big enough to fit over the outside of the dust bucket for the smaller dust collector.

At the art academy where I work we have a machine that compresses the wooddust into circular packets like hockey pucks. Really awesome to see.

Do you make a living working in your shop other than youtube and patreon?

Plastic teflon coat all the different pieces man.. Will make less noise and attract less particles..

Maybe covering fins with some sort of air collector that wraps airflow around the motor heatsink can help cooling it at lower speeds.

if you put a vacuum port at the bottom and outside the bag will it hold the bag open in the box?

Nice video. Good to get updates. Mahalo for sharing! : )

Why not putting a 120liter bag in it? (dust case)

When I empty my dust collector, I take a 30gal bag, slip it over the collector's bag, flip the whole thing, and slide the collector's bag out. Works pretty well.

You may use lazy susan for motor mounts. It removes the load on the motor shaft.

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

the clap 9:17, reminds of a video of a guy closing his hatch onto his ladder and shattering the glass.

11 fins? Only for that reason or why not 10? 13? :) But yes, it would be very interesting =) Any pros and cons regarding the 0.8 and 3 mm poly.. uh, plastic? 0.8 is not available here and no real translation for road glass that makes sense!

Well the similarities between your dust collector and that company's is too coincidental. They got a great deal out of your research testing and engineering ingenuity. RU-vid has it's disadvantages. Sure, they quickly copyright strike music and such, but how about some company obviously "stealing" ideas? hmmmm.
