It's been a long time ago that I added it. On the newer one, I had a board in there all along.

try finding a clear plastic bucket!

I liked that, too :D I woulda been tempted to put an RGB LED one in there! Green for Halloween :P Look like something from Tommyknockers :D

Matthias Waldel A cheap champagne bucket ; )

Matthias Wandel Exactly. So I would've tried to fabricate it by thermoforming clear sheet plastic, which would've taken many extra hours of work, only to (re)discover that clear plastics tend to be weaker than translucent HDPE or PP. One good chunk of wood smacks it just right, and it'd get a crack that starts spitting dust and all that extra effort would've been wasted, as strip by strip the whole thing gets covered in duct-tape.

welcome to Australia where out bearings seaze from the heat

Toby Wenman Welcome to Detroit where the Motor gets stolen by a crackhead for the copper.

welcome to singapore where we get china motors and bearings engineered to fail within a month or two

Welcome to India where we get 65% discount on list price of motors

Welcome in germany. The motor just runs.

I was thinking more of a Roomba :D

No kidding. No point in dust collection if you breathe it all at once.

No design is perfect, designs are in a constant state of transition. They is why CAD was invented, no drawing is perfect, drawings are in a constant state of transition.

But he definitely can analyze and learn of his mistakes. That's why he is as great as he is.

Oh no, here we go again.

I actually intended the comment to be humorous. I'm pretty sure, considering the videos Matthias has done on dust particles and collection within the shop that he of all people would know that and see the irony. When I commented, few others had commented so I figured it was a perfect time for the most obvious one.

have used bent wood. Would be tricky for the housing, especially with the hole in the side. building it up in sgments was something that I knew would work for sure.

Universal motors aren't really suitable. And top loding washer motors run at 1750 rpm, too slow.

Paul Smyers What about cooling your pc desktop?

what about drying paint?

Fjolfrin the Silk Beard loool

Felix Modellbusse I had the same idea.

paul loper yes, and I think if you know the big tablesaws in workshops their dust collectors sounds like they start rotating with out building a vacuum I think.

Felix Modellbusse Maybe he made the hole a little too big. This way there is not enough resistance.

Grease would be too thick

Have you tried lithium grease?

Then go back to the other video before commenting. How difficult would that be?

held the can on the output and noticed it got quieter

@@matthiaswandel was that the first thing you tried for your ghetto harmonic balancer?

Not at all. A full can did nothing whatsoever!

Christopher Silvia what i came to the comments to learn

Look up a closed-end air column. Basically the sound wave will enter the tube and bounce off the closed end. Depending on the wavelength of the sound and the length of the tube the reflected wave will be "inverted" but with equal amplitude. When this happens the incoming and outgoing waves will cancel at the mouth of the can. This doesn't work with all frequencies that his machine produces. But because machines typically only produce a hand full of frequencies that are actually loud, he can "tune" his can to eliminate some of them. In his case it sounds like it eliminates the high pitched whiny frequencies.

he explains it in the build videos

Good explanation! I hope there was a resonator to eliminate all the high pitched whiny KZfaq commenters :D

Put giant coffee cans over their heads.

Feldspato Quak take a look at the last video he posted....

Feldspato Quak He has a playlist on making a 16 inch bandsaw on his channel, as well as plans on his website.

Thank You!

I'm checking this out on his website

Chance discovery. I was trying to figure out ways to reduce the noise, nothing really worked, but I noticed a plastic container held near the exhaust reduced it slightly, so then went to figure out the best size of container.

very smart. Usually, if you put something infront of the air outlet, especially in an angle, it makes noise. Many musical instruments works that way. It's very surprising your tin can actually reduce noise. Great job!

Are there any inverter drives that step up the voltage? The ones I know just rectify the input voltage and use it to feed the inverter, so the output voltage cannot be higher than the input voltage.

Here's an example: www.automationdirect.com/adc/Overview/Catalog/Drives/GS1_(120_-z-_230_VAC_V-z-Hz_Control)

Bigger ones are available from other manufacturers, but the maximum horsepower is subject to the limitation of 15 or 20 A max from a household circuit.

bigger is better if you need bigger.

Matthias Wandel I am a mature beginner but bought a cheep plastic cyclone and attached it to a plastic paint bucket lid and household vac.I do not know much about motors but have a kitchen cooker extractor which I have ideas about.Shall have fun experimenting with it Maybe I should leave the bucket half full of paint and when it set with sawdust I would produce moulded stepping stones

He who cleans the vacuum cleaner BECOMES the vacuum cleaner.

this makes no sense. Each cyclone has a lot of pressure drop - and the separation ability is to a large extent a function of pressure drop. Just make your first cyclone spin faster.

Matthias Wandel, I actually made a two stage cyclone and need no filters at the end. The trick is to make many smaller cyclones in stage two that will separate the fine dust but still allow full air throughput. it's built and working and I'm very happy with it. My small basement cave is nicely clean after having used it for 6 months. I believe cyclones and filters are enemies. I have made a rather boring video about it.

+Henrik Larsen It seems to be interesting, it looks a bit like a dyson. Was this the idea to make it similar or how did you come to this concept?

moninum it was dyson that showed me that the fine dust must be extracted at very high g forces. I then designed this to aim for that. And it worked.

You will still need a filter after the cyclone.

Paulo De Oliveira I have been thinking of doing that in the last two days great minds think alike lol I have also been thinking of water as the final filter using an old wet and dry vac

Paulo De Oliveira ps great videos very inspiring thanks a million

Water isn't great filter, you need to renew water every few days or it will get very lively :) I prefer any cheapest car air filters for that kind of thing. Also, winding 2-3 layers of paper towels around it helps a lot. Doesn't really affect airflow, but makes cleaning much easier and filter will last longer. If you need to filter really tiny dust, you could use 3M filters for toner or some analog, about 10-13$ each.

Thanks for that what about a lot of salt in the water

He probably salvaged it from some old tool. In most cases you can get away with using a regular light switch.

Yes, from the old tool

The first filter becomes the most efficient simply by dust buildup on it.

Matthias Wandel frigging genius man!
